LG UltraFine 5K review: It's good, but it's not Apple

UPDATE: Wi-Fi routers caused disruption of early LG UltraFine 5K displays when placed in close proximity. LG has since fixed the issue and current models should be fine.

When Apple debuted the latest generation MacBook Pro back in October, 2016, they debuted a new 27-inch 5K display along with it. It wasn't just high-density "Retina" quality either, it was wide color, able to show the same DCI-P3 gamut that digital cinema uses. It was everything everyone waiting on a new Mac display had been waiting for. Except for one thing — it was LG designed and branded, not Apple.

That's not to say Apple didn't have a lot to do with the engineering — everything that makes it work so well with a MacBook Pro using just one Thunderbolt 3 cable. But the outside, what we look at, is nothing like Apple.

There are also compromises here. That gorgeous image and convenient charging all in one cable comes at a price — there's precious little bandwidth left for other ports and peripherals.

So, is the display good enough that we shouldn't judge it by its branding, or are the lack of design and expandability deal-breakers? Let's take a look!

About this review

I didn't get a review unit for the LG UltraFine 5K display. Instead, I ordered two of them the moment they became available. I wanted two so that, initially, I could test the double display set up on my 15-inch MacBook Pro 2016 review unit. Long term, though, I'm looking to simplify my computing experience. So, instead of a MacBook or MacBook Pro to travel with and an iMac in my studio, I want to go with a single new MacBook Pro that I plug into an LG UltraFine 5K display on the standing desk in my studio and, for off-hours, into the second display at the standing desk in my living room.

Over the last week I've tested both setups, the latter with both the 13-inch MacBook Pro 2016 with traditional function key row (MacBook "Escape") and the 13-inch MacBook Pro 2016 with Touch Bar and Touch ID. I made sure I attached everything I needed, including USB cameras, microphones, and drives, and Ethernet networking. I also tested it on the 13-inch MacBook Pro 2014, which can only drive it at 4K.

Yes, all with the requisite replacement cables or dongles.

For people who want:

  • A 5K external display for MacBook Pro.
  • DCI-P3 wide color gamut.
  • Single cable for display and charge.
  • USB-C expansion ports.

Not for people who want:

  • An Apple-designed external display
  • Ultra-wide aspect ratio.
  • Larger than 27-inch display.
  • Legacy Ports.

In brief

The LG UltraFine 5K display is a gorgeous, high density, wide gamut panel enclosed in a somewhat drab, utilitarian case. It can transit 5K at 60 Hz and power all over a single Thunderbolt cable but that leaves only three 5 Gbps USB-C ports for peripherals. In other words, this is not the display Apple aficionados have been waiting for. It's a compromise. Technical limitations means there's not much we can do about the lack of ports but wait for future chipsets. The design, however, was entirely avoidable. It's simply not up to Apple standards.

It does offer a few features Apple wouldn't have, including a stand that can be raised or lowered vertically, not just tilted to adjust angle. LG also includes a VESA mount in the box. Kudos on that. But the stand does not feel as solid as the old Thunderbolt one, nor the tilting mechanism as smooth. It also doesn't match the finish on Apple's current Retina displays.

For those who dislike or simply don't care about Apple's sensibilities, all of the above might be seen as a positive. Most Apple customers, though, do care.

I bought the LG UltraFine 5K display because there simply is no other option from Apple. If there had been, though, I would have bought it in a heartbeat.

LG UlraFine 5K Unboxing

The LG 5K box is thicker than the tapered box Apple uses for the iMac with 5K Retina display. It's more like the boxes LG uses for their television sets, which makes total sense. But it also made for some annoyance.

Opening it up, I found a lot of loose styrofoam, which was annoying because it got everywhere and I had to break out the vacuum cleaner to fully Ghostbuster it back to the hell from which it came.

The display was also covered in what looked like 1960s science fair inspired silver wrapping. It slipped off with only slightly more effort than Apple's typical translucent wrapper. Horrifyingly, to reveal a sticker on the top right corner of the display itself. It was an EnergyStar certification sticker and it came off easily enough. I appreciate the sentiment but, seriously, putting a sticker on a display? Don't. Just. Don't.

Also included in the box was a manual and a VESA mount. That's a great addition by LG, notably because it was something you had to pick exclusively, and prior to purchase, from Apple. There's also a power cable for the display and a Thunderbolt 3 cable for connecting to your MacBook Pro.

All in all, it wasn't an Apple unboxing experience but it was easy enough to unpack and set up.

LG UltraFine 5K Compatibility

Apple announced the LG UltraFine 5K alongside the new, 2016 MacBook Pro, and that's really what it's designed for. Using the 13-inch MacBook Pro 2016, you can drive one 27-inch LG UltraFine display at its full 5K resolution at 60 Hz. Using the 15-inch, you can drive one on each side for a total of two.

You can also use it with an older MacBook Pro but with a few of caveats:

  • You can only drive it at 4K, not the full 5K.
  • You only get sRGB color space, not DCI-P3.
  • You need a Thunderbolt 3 to Thunderbolt 2 adapter and a Thunderbolt 2 cable for the connection.
  • You won't get a charge from that cable, so you'll need to plug in power separately.

I tested with that set up using my old 13-inch MacBook Pro 2014 and it worked fine and looked great. It just wasn't as clean or as dense as using it with the new MacBook Pro 2016.

Here's Apple official compatibility list:

5120 x 2880 @ 60Hz

  • MacBook Pro (15-inch, 2016)
  • MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports)
  • MacBook Pro (13-inch, 2016, Two Thunderbolt 3 Ports)

3840 x 2160 @ 60Hz

  • Mac Pro (Late 2013)*
  • MacBook Pro (Retina, 15-inch, Mid 2014) and later
  • MacBook Pro (Retina, 13-inch, Mid 2014) and later
  • iMac (Retina, 27-inch, Late 2014) and later
  • iMac (Retina, 21.5-inch, Late 2015)
  • iMac (21.5-inch, Late 2015)
  • MacBook Air (13-inch, Early 2015)
  • MacBook Air (11-inch, Early 2015)

3200 x 1800 @ 60Hz

  • Mac mini (Late 2014)*

That asterisk is Apple recommending you not use the LG display as the primary display on a Mac mini or Mac Pro, since it may not light up until after you boot, rendering pre-boot options unusable. Sadness.

Ultimately, it's only worth driving the LG UltraFine 5K off an older Mac if you plan on updating to a new, Thunderbolt 3 Mac fairly soon. Otherwise there are a lot of good alternative displays out there.

LG UltraFine 5K Design

The LG 5K UltraFine Display in many ways is the next-generation Apple Retina 5K Display. Apple worked extensively with LG on the product engineering in order to make sure it "just worked" when you plugged it in. The design, though, is pure LG.

And it's not great. It's bland and boxy and looks like any of dozens of the other displays crapped onto Best Buy shelves every year. What's especially galling is that LG is capable of much better design than this. Some of their 4K OLED televisions are gorgeous. Not Apple at all, but still incredibly attractive.

That Apple didn't fight for a better design is bedeviling. That LG didn't have enough pride to do it anyway, shameful. Yes, it would have cost more, but Mac displays are a premium product and great design is something people are willing to pay a premium for. Especially when Apple announces it on stage. Leave bland and boxy for the discount displays that inevitably follow along later.

It probably all came down to a business decision on the part of Apple not to design their own display and LG not to better design this display. And that's too bad. The display is the interface to the computer. It's what most of us look at and allowing that critical relationship to fall under LG's flag, and such a utilitarian flag at that, is risky. Halo effects take years of investment in full ranges of products to build. Horn effects take only a few critical missteps to lose.

Of course, some people won't care. Once the display lights up, the big black bezels disappear into the background and all you see is the image on the screens.

It's not all you'll feel, though. The stand does raise and lower, which is something Apple's Thunderbolt displays never did. But the hinge for the tilt just isn't as smooth as Apple's. Likewise, while the stand is satisfyingly heavy, the structure isn't as solid or rigid as Apples.

There's a reason Apple uses bead-blasted aluminum unibodies and glass, after all. And LG didn't use either. They used black plastic and you can both see and feel the difference.

It's not a deal-breaker for me, obviously, but if there had been an Apple alternative, I'd have bought it instead without a moment's hesitation.

LG UltraFine 5K Display

Rumor has it the LG UltraFine 5K display uses the same if not a very similar panel to the iMac with Retina 5K display. To my eyes, though, it isn't as glossy. That'll please those who prefer more matte displays. Personally, though, I find the slight difference distracting and would have preferred if LG had finished it to match the MacBook Pro exactly. It's especially noticeable when looking at both the MacBook Pro and the LG display at an angle.

If I'm only looking at the LG display, though, I don't notice it at all. I'm absolutely lost, the same way I was in the original iMac 5K display. There's just something about that size. It fills enough of your field of vision, at such a close distance, that it feels like IMAX. Especially when the density is high and the color is deep. It almost feels supra-real.

Since 5K at 27-inches is the same density and size as Apple's iMac, the Retina story remains the same now as it did in late 2015. For comparison's sake, here's what the pixel counts look like for 42mm and 38mm Apple Watch on the left; iPhone 7 Plus, iPhone 7, and iPhone SE; iPad 12.9 and iPad 9.7/iPad 7.9 (same pixel counts), MacBook; MacBook Pro 15-inch and 13-inch; and iMac 27-inch and 21.5-inch on the right:

Specific to the 2016 MacBook Pro, here's a side-by-side of the 13-inch, 15-inch, and 27-inch displays:

That covers the resolution, now for the gamut. If you're not familiar with DCI-P3, it gives greater breadth than the older sRGB standard, which means brighter reds, deeper greens, and more luscious oranges and purples.

These days the 9.7-inch iPad Pro, Retina 5K iMac, iPhone 7 and iPhone 7 Plus, and the new MacBooks Pro all have P3 displays, and if you have any of them, you'll know it's hard to go back. Once you stare at a P3 display for a while, sRGB just looks... duller.

Some people have complained that their LG UltraFine 5K displays came incorrectly calibrated and had to recalibrate them themselves. I didn't have that problem. I know Apple individually calibrates most of their displays these days before they ever leave the factory but I'm not sure if LG does that or not. The two I bought are identically calibrated, though, and to my eyes match the colors of my MacBook Pro.

It's easy to see, because I've got everything running on my studio desk right now. So. Many. Pixels. But the size, density, and color depth are incredible to behold. It's like a high-dynamic range honeymoon that I never want to end.

It's especially great if, like me, you're shooting with iPhone 7 or iPhone 7 Plus. That way, when your photos sync back to the Mac, you get to see them on the big screen in the same spectacular colors you saw them on the small screen.

Speaking of sizes, I know some people would have liked a bigger display. Something along the lines of 30-inches or more. I personally don't like having to move my head or neck around that much when I'm so close, nor do I find the size trade-off worth the loss of density. I just really don't want to see pixels any more.

So, for me, 27-inches is the sweet spot. At normal working distance I can take almost all of it in at a glance and it's dense enough that it crossed the "Retina" barrier and looks like real life.

Of course, there are already 32-inch 8K panels being shown off at CES 2017, so...

Ports and peripherals

The LG UltraFine 5K display appears to have four identical ports on the back. If you look closely, though, there's a difference in how they'r'e labeled. The one on the right has a Thunderbolt 3 icon, and it'll pull 5K at 60 Hz from your MacBook Pro while simultaneously pushing back 85 watts of power. The three ports on the left, though, have USB-C icons, and they're only rated for 5 Gbps.

Getting the display and power through a single cable is a remarkable achievement, especially considering Intel keeps pushing DisplayPort 1,3 — never mind 1,4 — further and further out to the future. But it comes at the expense of other peripherals. You're not getting 4x Thunderbolt 3. You're getting 1x, dedicated to the Mac, and 3x USB-C for the rest.

I'm mostly using USB peripherals so it's not a big deal for me. If you really need higher-performance peripherals, though, you'll need to plug them directly into the Thunderbolt 3 ports on the MacBook Pro itself. And that defeats some of the convenience of having an external display-as-hub.

That's what I'm doing with my podcast headphones, since there's no 3.5mm headphone jack on the LG UltraFine 5K display either. It's a pain, since I was used to just leaving them plugged into my iMac and, before that, Thunderbolt Display. Ideally I'd just use AirPods or Bose QC35 and kiss the wires goodbye, but I'm still Galactica paranoid when it comes to hardlines for video or audio production.

That's why I also use Ethernet. I've got the Belkin USB-C to Ethernet adapter on order but it hasn't come in yet so I'm currently daisy-chaining an old Ethernet adapter to a new USB-C adapter, for the dongle double-down. It's ugly but it works.

I'm also using Apple's USB-A to USB-C adapters for my Logitech web cam and for the USB interface for my Heil XLR microphone. The LG UltraFine 5K display includes a built-in web cam and mic and they're fine for FaceTime or Skype, but not anything I'd use on a podcast or broadcast.

I've used a lot of dongles before. My old Mac Pro had display port extenders, HDMI adapters, FireWire adapters, and who can remember what else. It takes slightly longer and feels slightly sillier setting up, but once it''s done you forget about it.

But you see and enjoy that display every damn day.

LG UltraFine 5K Conclusion

I tried the LG 5K UltraFine Display at the Apple event back in October and liked it enough that, when they went on sale in December — and at a discount thanks to Apple's price cuts on all Thunderbolt 3 accessories! – I snapped up two of them.

Short term, I wanted to test how well my 15-inch MacBook Pro review unit could drive both displays at the same time. And the answer is: just fine. I've noticed no obvious slowdown, tearing, stutter, or freezing. It really does just work.

Longer term, I'm going to be living with one at the standing desk in my living room, where I work off-hours, and the other my studio, where I podcast and otherwise work from. Then, the idea is I'll switch my personal 13-inch MacBook Pro between them. I'm hoping that'll once again let me simplify my computing experience, since it's light enough to travel with and powerful enough to do full-on production.

So far, that's worked out just as well. I did have some trouble with the 13-inch MacBook Pro with traditional function key row at first but once I ran software update, it worked fine. The 13-inch MacBook Pro worked fine from the very first time. (I'd already updated it.)

I don't like the LG UltraFine 5K as much as I do the iMac with Retina 5K display. Apple's design is better in many, many ways. I do like that I can easily adjust the vertical height, though. Previously I had to buy and improvise risers.

Ultimately, though, the LG UltraFine 5K is the external display we have, not the one we deserve. The one we deserve would require Apple take back control of the complete experience.

  • "So, to me, yes, it matters. I would greatly prefer if this display was in an Apple casing with an Apple logo. But, it not a deal-breaker for me. Obviously." Sure that's not just your vanity being set off?
    How about the White House? What are your feelings about that? :-) "Personally, though, I find the slight difference distracting and would have preferred if LG had finished it to match the MacBook Pro exactly." I could see why YOU would prefer that, but this display will also be used with other brands and models of computers. Last I checked, it's still something like 9:1 when it comes to Mac against the world. In the spirit of the season, let me be generous and say its 8:2. That does not change the point.
  • I'm not sure the ratio of Macs to whatever really has any baring on one's personal preference of the finish of a monitor. He didn't say it should match MacBook Pros, he "Personally" "preferred" a match. Give a guy a break.
  • Just pointing out some of the obstacles to achieving his desires. LG is not Apple, they play with everyone, so they can only accommodate so much.
    Match Apple's finish, HP complains, match HP's, Dell complains. Actually, they likely wouldn't complain. They're not at Apple's level or flavor of narcissism (though they would serve us all better if, in part, they were). "There will be no swimming today, Carlo is using the ocean!" ;-)
    (A true humorous story about Carlo Rubbia, Nobel Prize winning physicist)
  • The LG UltraFine displays are designed to be used exclusively for the Mac. See the packaging and product page on LG's site. So with that said, wishing it took on a more Apple like design is certainly warranted.
  • Okay. Fair enough. Also fair enough that I wouldn't buy it though it would most likely work, unless it's intentionally crippled. Why would LG not want to sell non-Apple users this monitor?
  • "I could see why YOU would prefer that, but this display will also be used with other brands and models of computers." Actually, last I was aware, there is no built-in display interface. It was designed to be used with Mac only, as the Mac has the drivers to adjust brightness etc.
  • Under their software downloads the only thing Mac specific is the screen manager software. The interface is TB3, which several PCs have, including my Dell XPS 13, or can be adapted. This does not seem to be an Apple only minitor. What sense would that make for LG?
  • Oh boy. Between all those dongles hanging off the back, and the thick black bezels, this is definitely not an Apple-like experience anymore. However, if you need a screen with these specs, I guess this is what you have to put up with. Would definitely like to see a comparison with the iMac, because this might be a better way to go if you plan to do a lot of work at your desk.
  • I was thinking, okay, that would make a good second monitor for my iMac... then I saw the price. I could almost have a second iMac for that price! I think I'll wait for the competition to start. Samsung?
  • Here's a list of 5k competitors: https://en.wikipedia.org/wiki/5K_resolution#Monitors They are all priced about the same or higher than this LG. The well-reviewed DELL UP2715K is over $1,500.
  • none of those have P3 color, though. ...It would seem they do not use the LG panel. ...and, I didn't check, but, I don't think any of them have one connection, but, two cables required to drive the 5K resolution, only the LG uses TB3 so it can do everything in one cable (5K resolution/P3 color/audio/mic/camera/charging all go through the one cable).
  • Good points. I was actually arguing the case FOR the LG monitor being a good value. I was solely focused on the 5K-ness of the monitor, not the connectors, but your notes make the LG only look better. Thanks.
  • oh, I knew that, I just wanted to point out the differences. Apple always prefers simplicity/minimalism, one cable that does it all is preferred, even if it means not backward compatible, and that's what they worked on with LG. ...For those other monitors one would need to use two display port connections, so your computer would need two DP outputs to use those monitors at 5K resolution. (or maybe 2 HDMI 2 ports with "not included" cables.) ...They probably didn't even think of using TB3 to drive their monitors.
  • ...those 5K monitors use 2 DisplayPort connections. ...The HP includes 2 DisplayPort cables.
  • Thought it might be worth mentioning this to the group... I have the 4K LG, connected to a MacBook. Have found with much trial-and-error that when connecting or disconnecting the monitor, the MacBook needs to be awake with the lid open. Initially, I would leave the MacBook closed and just plug-in or unplug the USB cable to the monitor and drop the laptop into it's stand. The display on either the monitor or the laptop would be black, and stay black. All that would show thru the black was my dock icons and the mouse cursor. After a few minutes, it'd go back to normal. An Apple tech confirmed his suggestion is to always wake the laptop before connecting an external. Love the monitor by the way , although the MacBook is an expected performance dog :)
  • Mine worked for less then 5 minutes then died. I had a 4K display before that and it wouldn't work when plugged on one side of my late 2016 MBP. Returning the 5K and getting a new unit but I'm not very hopeful at this point. I can't believe Apple left the display business to LG. Such a horrible experience. I guess this is the new Apple under Cook. Profits before user experience.
  • That's horrible! Both of mine have been working fine since I got them.
  • Wouldn't this work with any computer supporting USB C displays? Posted from my Nexus 6P
  • No. "System Requirements
    Operating System: macOS Sierra 10.12.1 or later
    Connection: Thunderbolt 3–enabled Mac"
  • Are you sure? I'm not talking about what's on the box. Does it really not work? If that is correct, it's intentionally crippled. Why not be able to use it on any computer you own with the correct interface. In this case it's TB3. Still, it should work with the correct adapter. Not for charging mind you, but as a monitor.
  • I don't know about other computers but older macs can connect via adapter, but only able to use it at 4K resolution: http://www.macrumors.com/2016/12/20/lg-5k-display-works-with-older-macs/
  • The OP asked about "...computers that support USB-C displays". That's an odd and unclear phrase, but I took it to mean that the OP wants to connect via USB-C. That is not possible since this is a TB3 display. Your comment is valid however, the "macOS Sierra 10.12.1 or later" requirement is suspect. Why wouldn't this monitor work with any TB3-equipped machine?
  • From what I understand, this monitor has no physical buttons and relies on the controls built into the Mac OS. While it may respond to a video signal coming off a TB3 equipped Windows machine, you may have issues actually trying to use it. I would pick one or more of these up if it was guaranteed to work with my desktop but until that's confirmed I'll wait for something brand agnostic.
  • I can't see why not, it's a monitor at the end of the day
  • "Why not four Thunderbolt 3 / USB-C ports at full 40 Gbps bandwidth?" Thunderbolt has always been daisy-chain only. That's why every single thunderbolt hub on the market only has two TB ports (one for in and one for out). In a roundabout way, you do pose a good question though. TB3 supports USB speeds at 10/Gbs. Why are the USB-C ports on this monitor only 5/Gbs?! It's like hooking your firewire 800 drive up to a firewire 400 port.
  • Running the 5K display at 60Hz with 10-bits per subpixel is taking almost 25Gb/sec of bandwidth before you add in peripherals. The 5Gb/sec seems to be to give each the same amount of bandwidth from the remaining 15Gb/sec left on the TB3 connection.
  • Twice you compare P3 to "sRGP" — do you mean sRGB? I've never heard of sRGP as a standard, though maybe I am just out of the loop on technologies in Apple displays. Also, is this information verified:
    The reality is this: Apple helped engineer this display to such an extent that LG wrapping and labeling it probably came down to nothing more or less than a business decision. Internally, it's the same or highly similar to the panel in the iMac with Retina 5K and P3 display introduced in October of 2015. Given that LG has a huge display business and expertise, and how closely Apple holds its technologies to its vest, I'm guessing the opposite is true. Apple didn't want to design/sell its own monitors anymore, but didn't want pro users to freak out, so they decided to pay lip service to a partner's product. I doubt it's much more than that. If Apple labored over every detail of the internals, do you really think they'd allow LG to slap their name and a cheap plastic shell on it?
  • Apple is upping the ante with P3 color gamut on all of it's new devices. (P3 color gamut is currently used in movie theaters and is newly available with the new UHD standards for 4K home theater devices). ...I think apple wanted to give their users the same experience as on their products, but, save $ (and keep the price down for us), by working with LG, who makes their displays for the iMac. They also wanted one-cable connection, which is not possible without DisplayPort 1.3, which, has been delayed due to the need for Intel's next gen. CPUs to drive such. So, Apple is bypassing DisplayPort and using the TB3 data path to drive the 5K resolution, since TB3 has 40G available whereas DP1.2 has only 18G available (max. 4K res.).
  • Yes, I'm verifying that Apple expended considerable engineering resources in the development of this display with LG. I would, and I think many at Apple would, have preferred they go the whole way with the design too.
  • Buy the monitor that suits you, its an investment you'll own for as long as your devices will cast video to it. Invest in a good monitor, keyboard, mouse, and audio. Save money elsewhere.
  • Two DisplayPort streams are required to send the full 5K resolution over a single cable. Each stream contains half the display signal and the system merges them into a single image. If a PC can perform the same signal splitting and combining then it will work with the display.
  • Almost got it, for PCs, they have to use two DP cables to drive a 5K monitor for the reason you stated (however, that is not possible in this case, as no way to connect that way). DisplayPort is used to drive up to 4K resolution, as, this iteration of TB3 includes DisplayPort 1.2, DP 1.3 has not been implemented yet, I think it's coming with next generation intel CPUs. Apple has implemented this differently, not sure if it's proprietary, but to use the single TB3 cable connection they are actually using TB3 data signal to drive the 5K LG monitor, (which would explain why no TB3 hub, as it is also the one connection utilizing the built in speakers, camera, mic and USB-C hub, along with providing charging power for the MBP). ...This is why the new MBP 13" w/2 TB3 ports can only drive one 5K or two 4K displays, MPB 13" & 15" w/4 TB3 ports can drive two 5K (one off either side of the MBP) or four 4K displays.
  • Intel pushed DisplayPort 1.3 out to at least Coffee Lake, maybe Cannon Lake. Basically, I'll believe it when they ship it. And, of course, DisplayPort 1.4 is the latest standard, so we'll see if that takes its place or is just further away...
  • (typo: sRGP instead of sRGB) ...you mention needing dongles, however, you didn't really explain that: With the one TB3 cable connection you get 5K resolution, you can use the built-in camera & mic, audio (speakers are built in to the monitor), up to 85W charging for the connected device, AND the USB-C hub on the monitor. Also, there are other options than using dongles (if at a desk or parked w/power available), here are just two examples: USB-C dock (gives you USB A ports, ethernet and much more): https://www.imore.com/e?link=https2F2Fclick-100048... TB3 dock (pre-order) (gives you USB A ports, ethernet, TB3 hub and much more):
  • Thanks, fixed. The docks are certainly an option, as is replacing the cables. I prefer the directness of the latter, but the utility of the former will no doubt appeal to many. Cheers!
  • Happy New Year. I would be interested to know how the 5K performs as an external monitor for the latest iMac. My understanding is that: 1) it works; 2) it displays only 4K. Could you tell us what those 4K look like?
  • You can connect it by using a Thunderbolt 3 to Thunderbolt 2 adapter and Thunderbolt 2 cable, and it will indeed work at 4K. It looks fine, just not as dense as 5K.
  • Rene, would you mind commenting on the performance of the 13 inch? Was it acceptable to you at all times? I have a 13 3.3/16/512 now and a 5k on order and want to make sure the performance seemed good to you with the Iris Pro vs the dedicated graphics of your 15 inch review unit. Thanks.
  • I've been using the 13-inch i5 the most and it's been fine for me, even with Final Cut Pro. I'm valuing battery life higher than absolute performance though, so that's the best balance for me.
  • Rene, could you please specify specs of your 13'' MBP? Processor speed? RAM? I'm thinking of getting the base Touchbar 13'' MBP with 2.9GHz/8GB RAM and want to be sure that it will works well with the UltraFine 5K. Thanks.
  • Maybe I missed it, but did you test with the lid closed on the Macbook Pro? I'm having some issues where I'll leave it plugged in when I go to bed, come in the next day and the display won't wake up. I have to open the lid to the Macbook Pro then the display comes on, then I close the lid again. Sometimes that will work. Other times I need to completely unhook everything and start over. Also, I have to plug in my ethernet to usb-c directly to my laptop to get the full speed out of it. I'm guessing something about the 5 GB connections on the back is limiting it somehow :( I'm thoroughly unimpressed with this monitor now. I do like the display but there are so many inconveniences so far that I'm seriously considering taking it back. But then I'm stuck with: What do I replace it with? Do I adapt a display port to usb-c and use up another port to power my mac with it's power brick? Yeah this is a mess Mr Cook. And if I weren't using it for iOS development I'd seriously consider getting a PC to run some Linux variant on it!
  • I did test it that way but I don't recommend anyone use it that way. Modern thermals are such that the more heat you can radiate out — which means keeping it open — the better. What speed are you getting over Ethernet to the display? The advantage for me is stability and removing points of failure. I don't think I've ever saturated it.
  • Wow, ok I never knew that and I've been doing this for a while! I'll try leaving it open and see how that goes. As far as the speedtest, I'm getting 203 down/ 455 up connected to the back of the monitor. Connected to my laptop direct, I'm getting: 758 down/500 up. It's odd that it's not symmetrical down/up given this AT&T Fiber. I've gotten as high as 900 down on the direct connection to the laptop.
  • Hi Robert, I just purchased and connected two LG 5K displays to my new MacBook Pro. I also like to keep the lid closed at all time and am not experiencing any problems with it. when I get up in the morning, I simply move my wireless mouse and both monitors come on. Not sure what settings may have caused it to work right but you I set up energy saver on my MacBook Pro to "prevent computer from sleeping automatically when the display is off". I also set up to "never turn off display when in Power Adapter mode". Hope this helps.
  • How about a 32" version? ;)
  • How do you think using the LG Ultrafine 5k with an old MacBook Pro compares with using a 4k display e.g. Dell P2715Q? Does the fact that the LG is not running at native resolution make a difference?
  • Good review. I really do not like the design at all. I think it is a bad move for Apple to abandon monitors and wifi routers. They don't sell as much as iPhones, buts its very important for reasons that you know. Apple may have to learn the lesson the hard way, which is unfortunate and unnecessary.
  • Thank you for testing the LG with an older MBP! I'm very curious about this, in order to figure out, if it's smarter to get a Dell P2715q for my mid 2014 15" MBP until I upgrade to the 2016/2017 MBP later or get the LG now in preparation for the upgrade and meanwhile run it in 4k mode. Do you have more info on the possible limitations of running the LG with older (but according to Apple compatible) MBPs via the Thunderbolt 2 adapter? I wonder about the following things... Is the sound working? Can the display still be adjusted (brightness, etc.) via the keyboard? Are the USB-C ports functional, i.e. is it possible to plug in the ethernet dongle and get an ethernet port and a USB-C dongle to plugin a blueray drive or memory stick? How does the upscaled 4k picture compare to a native 4k picture? Any information bits on would be greatly appreciated! Thanks!
  • I'm wondering the same thing. Some in depth infos about how the picture looks like on the old equipment would be EXTREMELY appreciated. Is it comparable to a 2715Q scaled to 1440p? (In regards of the crispness). Or is it worse? Is it usable as a main display, without compromise?
  • Thanks for the in-depth review! Pretty wild that the 15inch mbp can run both displays at 5k 60hz, makes me wonder why people were lamenting the end of "pro" apple devices. AND wonder why anyone would by a current Mac Pro vs this new laptop.
  • I bought this to run along side originally a late 2014 iMac and now on a late 2015 i7 4.0 32GC 4 GB video. the LG screen flashes off for about a second every 1-3 minutes. Enough to be very annoying. Is this happening to anyone else?
  • Mine flickers once in a while, not as often as you mention. I notice the laptop's display does the same. Not sure the issue with the LG display.
  • Has anyone who owns this monitor noticed an issue with audio volume? I received my LG 5K monitor yesterday to use with a 2016 13" MacBook Pro w/ Touchbar. When I am on the lowest volume setting (1 bar), the volume is *way* too soft. But when I select the second to-lowest setting (2 bars), it is much too loud. And anything beyond 2 bars is super loud - too loud for an office environment (I have a closed-door office, not a cubicle). I have a colleague with exactly the same laptop/monitor setup - and he has experienced the same issue with volume. So that confirms that it is not an issue with my particular monitor or laptop. Has anyone else experienced this? Or more importantly, found a resolution? Thanks!
  • I have the same problem (same laptop). No resolution. I'll reply if I find anything.
  • I called LG yesterday and they said that they had "multiple reports," and so are looking into this volume issue. Hopefully it can be resolved through a firmware update.
  • Just got one. Similar setup (2016 15" MBP w/ Touchbar), same issue.
  • It's funny, after using it for just over a week, my take on the UltraFine monitor is quite different from Rene's. I'm absolutely fine with the aesthetics. It's the parts of the monitor that are so very Apple, that _scream_ "Apple", that are making me seriously consider returning it. I've owned a few Apple displays. The last one I bought had a CRT. After that monitor—which was awesome with the computer it worked with, and unusable with anything else—I swore I'd never buy another Apple display. After a bit of a wander, I started buying Dell displays, and have been generally-to-very happy with them. The three year old 27" Dell that the new UltraFine displaced is, even today, an outstanding display. So good I might just go back to it. The sticking point is, I have a personal MacBook Pro (brand new 15" TouchBar) and a work MacBook Pro (2.5 year old 15" retina), and the UltraFine has just one input. The whole promise of connecting the new Thunderbolt 3-based Mac to exactly one cable gets blown out of the water when I have to unplug that cable _from the back of the display_ whenever I want to earn a living. (Because the older, Thunderbolt 2-based laptop can't use the new USB-C cable; it uses the Thunderbolt 3-to-2 adapter, and an existing Thunderbolt 2 cable.) That's usually two+ cable swaps a day. And here's the kicker. My work laptop is due for replacement. Indeed, it's been eligible for replacement for six months. But the rollout of the new TouchBar MacBooks is going very slowly at large enterprises, mine included. (Reasons: mostly supply, a 20K-employee organization has to be able to buy hundreds of laptops at a time, and the new models are still constrained. But also, the new models are ~$200-500 more expensive to provision, between the mild price increase of the units themselves, and the cost of the dongles you need to give everyone who gets one. Multiply that by hundreds or thousands, and it's a non-trivial chunk of change.) I won't be able to get a TouchBar MacBook for, probably, another three-to-six months. Or longer! The UltraFine is certainly gorgeous, even when driven by the older machine. But the prospect of another three+ months of physically swapping cables is **** irritating. Especially when the displaced Dell display had _four_ usable inputs, and could swap between them with the press of a button on the face. And, except for not being retina / 5K, has a **** fine picture. No Apple display in my memory has had multiple inputs. I suppose I'm an edge case in finding them valuable. But, ****, when your use case can use them, you really, really, really want them.
  • Thanks for the review! I was leaning towards the 4K LG monitor, but am a professional photographer and think the 27" 5K version would be best for me and my 2016 15" MacBook Pro. Looking at the the text on the monitor at the Apple Store, it is noticeably smaller than on the 4K. Is there a way to increase it on the 5K without losing image quality or should I just get used to it? P.S. I just stumbled on iMore when looking for monitor reviews. What a great site! I will definitely add it to the list of Apple websites I visit every day :-)
  • Buyer Beware (check out the comments at apple's website for this unit)
    These units have multiple defects. I bought two of them. One no problems the other had sound problems. Working with LG support is a nightmare. Sent it back already once to get it fixed and it was not. Also they don't wake from sleep consistently. I also had flickering problems but that went away when I uninstalled LG monitor management software. LG Does not Support this Product Buyer Beware I purchases two of the units. One the sound was fine the other has a tinny ringing sound on certain songs. I asked LG for a replacement but they said they only provide return repair. So I sent it back and two weeks later it was returned but not repaired. No communication from the repair ship (which is a third party not LG). No notes no ability to amend a repair ticket. No way to communicate with the repair tech. After several hours on the phone talking to a supervisor who insisted that the only option was to send it back in again. I asked him what possibly would be done differently. He referred to the technician notes which he had access too (but not me) and said they replaced some shielding which has been problematic of these units. But it did not fix it. So I asked him what more could they do to repair it. He said it didn't know. etc etc. He said that it might not be repairable but only the repair shop could say that. So my only option is to send it in again and wait another 2 weeks and hope that something different happens this time. I talked to apple support who tried really hard to see if they could get replacement from Apple but because it was outside the 14 day window that was not possible. LG's support ticket system does not allow the user to add or append additional information. It does not allow the repair technician to amend are request additional information from the customer. Its one and done. I even called LG to ask them after I sent it back how it was going and could a send more information to the repair technician with a test to verify that it was fixed before they sent it back and LG's response was that they could not send any more information to the repair facility. They they had no way of communicating with them and that there was not way to amend a ticket. So If you can find a monitor from someplace other than LG that works for you. Get it as LG does not understand how to support the Apple market. Apple made a bad strategic decision going with LG as a partner making these displays.
