    LG's UltraFine 5K Display returned to the market earlier this month after LG made some changes to the display's shielding following the discovery that the original design left the display vulnerable to interference from Wi-Fi routers and other electronics. The issue was a bit of a black eye for Apple, considering the company recently elected to exit the display market and instead partnered with LG on the new 27-inch UltraFine 5K and its smaller sibling, the 21.5-inch UltraFine 4K.

    We purchased one of the original UltraFine 5K units back in December, with our model carrying a manufacturing month of November 2016 based on its serial number. LG has now provided us with a unit manufactured last month after the design revisions were put in place, and we've had a few days to compare the performance of the two units in the presence of Wi-Fi routers.

    In day-to-day usage, we failed to see any issues with the original model, even with an AirPort Time Capsule located just three feet from the display, inside the two-meter radius LG recommended users should keep as a minimum once the company discovered the issue.

    We were, however, able to induce the issue in the unit by bringing another Time Capsule into very close proximity with the rear of the display, causing it to flicker and disconnect from the host computer. The display sometimes reconnected to the computer on its own once the interference was removed, but other times it required that the Thunderbolt 3 cable be briefly unplugged or even the entire UltraFine 5K be power cycled before it would reconnect.

    With the revised UltraFine 5K Display in hand, we've been able to subject both displays to side-by-side testing that confirms the issue has been successfully addressed. While the issue is easily reproducible on the original model as long as the Wi-Fi router is in close enough proximity, we were unable to recreate the issue on the revised model despite extensive efforts.


    With Apple once again shipping the UltraFine 5K Display, new orders are currently showing in-stock availability in Apple's U.S. online store, although Personal Pickup remains unavailable.

    Apple's discounted pricing on the display of $974 is scheduled to run through the end of this month, at which time the display will return to its normal $1299.95 price. Apple already extended its discounted pricing on USB-C and Thunderbolt 3 accessories once and it's possible the promotion could again be extended, but for those who want to make sure they receive the discounted pricing, they should be sure to order by March 31.

    Customers purchasing the UltraFine 5K Display, regardless of what vendor they use, should make sure they are receiving revised units to ensure they are protected from the Wi-Fi interference issue. The first three digits of the display's serial number (visible on the exterior of the box) correspond to the last digit of the year and the two-digit month of manufacture, so buyers should look for serial numbers starting with 702 or 703.

    Those who purchased earlier units may be eligible for repairs if their units are exhibiting the interference issue, and affected customers should contact LG or Apple for information on repair procedures.

    We've arranged for a repair of our affected unit through the live chat option. Once the repair request is initiated it can take a day or two to receive a shipping label and repair details, and LG tells us it can take up to 7-10 business days for the actual repair once the display has been received at the service facility.

    It would be nice if Apple and LG could now work together to fix the USB hub connectivity issues :-(

    Even though it was a botch job, it is commendable they owned it and addressed it instead of hiding in secrecy/being in denial.

    Still an awful mess of a display. Should have nothing to do with the Apple brand whatsoever. Completely off brand.

    I’d pay 25% more for this display, in an Apple enclosure. LG does make excellent panels, and my 65” OLED LG TV is in an arguably very attractive enclosure (even nearly Apple worthy), so I’m sure how this montior got out of the industrial design room.

    It would be ironic if the new production models didn't fix the issue.

    Apple didn't really have much choice. It wasn't working properly. It had to be addressed. That's as botched as it can possibly get. Apple should be more upfront with defective MacBooks sometime. That would truly be refreshing and open. Macbook issues seem to be more hush, hush, deny, deny, before getting fixed.

    The bolded part hit the nail on the head.

    LG is not an off brand. As LG Display is the only manufacturer of OLED panels in the highest end tv's, going into tv's from LG, Panasonic outside of US, and now Sony, I would beg to differ

    ACD branding would be better, but tons of iMacs and I think retina iMacs are LG display.

    Their panels can be quite nice and the most color rich, on LED front too, is my point

    I'm still bummed that Apple never made its own 5k Cinema Display. Wish they didn't abandon it. Would be nice to have the same quality external screen to match my Apple MacBook Pro. Oh well.

    My first Mac was a G5 and bought the matching Apple monitor. Even that was better looking than the LG one. How do users find the performance of the LG monitor?

    I think the biggest gripe against the LG 5K display, is its plasticky design. I don't think they're too many complaints against the actual display itself, it's more so the design and overall cheaper construction. Overall, I think the LG 5K display is really sharp monitor.

    I just don't like the look of the display. I'm sure it's nice, but it doesn't have that Apple fancy I'm used to. It looks plain and boring.

    Same. My PowerBook G7 really doesn't look great with this LG 5K display.

    Great, so glad this is now sorted. Now how about a modern standalone Mac desktop computer that can actually drive a 5K display?

    Honestly, I think plenty of us would be fine with an updated Mac Mini using some of the guts from the new Macbook.

    The new monitor's performance is superb, especially given its price! The Wifi interference issue doesn't affect me so I'm not even going to bother sending mine in for repairs. It's just too much hassle for something with a really easy fix if you have a little space to play with.

    That said, I've got some minor complaints about the monitor, but nothing that makes me regret getting it and I'm still amazed at how relatively inexpensive it was. I had a 30" ACD purchased in 2006 and I paid around $2500 US for it.

    I thought the lackluster design might bug me more, but really that's a nothingburger, especially when the display is on. That big top bezel? I don't notice it unless I'm looking for it.

    And in regards to that big top bezel... has anyone else noticed that the new MBP's top bezel is about the same proportion as the LG 5K's? It's surprising that nobody's complained about that given how much of a roar there was about the 5K's bezels.

    I had one of these monitors shipped back to LG due to the flickering issues. Upon receiving our fixed monitor, after about 10 minutes it started flickering again on and off, just as it did before we sent it off. We also see in the notes that they did apply the fix, so who knows. From my perspective it's just a bad 1st gen monitor, and will be returning to Apple.

    Could you go into more detail regarding what you are experiencing. I noticed for my client that upon plugging in the TB3 cable, her USB keyboard and mouse were not recognized and I had to unplug and plug back in the USB cable to get it working. Curious if what you are describing is the same issue.

    Just sent one of my two units in. Hoping they fix the buggy USB-C connections on the back. Occasionally those ports would stop working unless I unplug and re-plug whatever device I have in there (Ethernet adapter, External drive, or even lightning cable).

    Exactly. When I replug the thunderbolt cable, the devices connected at the back of the screen through the "hub" are not recognised. It seems to be a quite common issue:

    still can't figure out for the life of me why apple would go along with a 3rd party acting as the only solution to the monitor attached to the pro and mini?

    We just recieved our fixed one back and that's when I first noticed the USB-C issues, so my guess is there is no fix for that and yours will not be fixed.

    Then you would have been bitching about the price.

    They can make it the same size as the Apple TV while they're at it!

    Agree. Isn't it just superb how even some of Apple's decade old devices are still much more attractive than today's competitor devices. Just lovely.
