    A recurring issue with the LG UltraFine 27-inch 5K display that causes glitches whenever the monitor is placed close to a router will be fixed, LG has announced.

    Recently, reports began circulating online that LG's 5K monitor - created in partnership with Apple - suffers from flickering and freezing when placed close to a wireless router, with this behavior sometimes causing connected Macs to also freeze and require a restart.


    On Wednesday, an LG support person confirmed to ArsTechnica that the issue had been reported by a number of users and that it only seemed to occur with the company's Apple-approved 5K monitors. LG has now publicly apologized for the glitch and says all new models made after February will not be susceptible to the problem.

    Speaking today to Recode, an LG spokesperson said that the company will resolve the problem by inserting additional shielding into newly manufactured models, which should protect against the electromagnetic radiation from routers that is likely causing the issues.
    According to LG, existing models will be able to be retrofitted with the same enhanced shielding, allowing the monitors to be placed near routers without playing up. Owners affected by the issue are advised to get in touch with LG support using the number (800) 243-0000, or to visit their local LG seller to arrange for a repair.

    Apple teamed up with LG to create both the 4K and 5K UltraFine Displays, specifically designed to work with the new 13-inch and 15-inch MacBook Pro. The displays are a successor to Apple's own Thunderbolt Display, which it discontinued earlier this year amid its departure from the standalone display business.

    The 5K Display is currently available for purchase at the sale price of $974 until March 31, 2017, when the price will return to $1,299.95. Apple was recently falsely accused of hiding negative feedback about the new display on its web store, when the truth was that reviews had not yet been activated for the product page.

    Whatever the reason for the initial delay, posting to the product page has been possible since January 25 and reviews have so far been mixed. LG's display currently has a 3 out of 5 star rating based on 115 reviews, but it's not entirely clear how many of them are solely affected by the router glitch.

    Current owners are advised to wrap the backside in aluminum/aluminium foil.

    Nothing like testing a product before release is there!

    A display with no sheilding? I suppose they were trying provide a low cost monitor to the consumer by cutting back on expensive materials like tin.

    Seems some engineers at LG have brains as dry as a biscuit after a voyage.

    Can you not bring them to an Apple Store? This is probably why people want an Apple branded monitor. They know where to bring it for service.

    The 4K monitors report similar symptoms this problem allegedly creates, including kernel panics on the connected MacBooks. The high number of reports are keeping me from buying any of the LG UltraFine monitors. What other Retina display USB-C options are out there?

    Shielded wallpaper rolls are being shipped as we speak.

    Maybe LG left out the shielding so that screen would be thin enough to meet Apple's standards for thinness.

    how did nobody notice this in testing? Don't people take these things home for a month to see what actually using them is like?

    LG is offering to ship an EM shield for affected users to self install. How awesome is that!

    Ahhh...$1,000 for a display that took 5-6 weeks to ship and they expect people to ship it somewhere for repair. Yea right. This should result in an extended return window at any Apple Store. Essentially a recall. And, hopefully this triggers Apple to make their own display and stop suscepting Mac users to the black plastic world of PC users.

    They **** things up just like Apple, Google, Samsung, Microsoft, Ford, Toyota, Honda, Ikea, etc. All companies make mistakes... cuz people. How they respond to the mistake is what's important.

    Bet now they wish they had built their own monitor to avoid this embarrassment...

    Whatever happened to "It just works."?

    Because this was the Apple approved version.

    Given that their own monitors can now crash connected devices, maybe it's time Apple stop showing Windows PCs on a network as CRT monitors with the blue screen of death.

    The monitor has shielding, just not enough of it (or the existing shielding isn't in all the right places).

    Almost certainly not. The UltrFine monitors are not covered by AppleCare. Just a two-year, "limited" & non-transferrable (!) Warrantee from LG. [Unlike Dell, BenQ, Phillips, etc - there is no 3-year guarantee option for LG monitors]. And apparently, there are no local drop-off locations either.

    They tried a Mac version. But you couldn't read the kernal panic on such a small icon. So they decided it should automatically appear full-screen.

    Taking things to the next level, Apple decided that we should also enjoy the full experience.

    Apple should make a brand new Thunderbolt Display 24-inch.

    All 12 owners will be inconvenienced by needing to visit an Apple Store.

    It's likely that an issue like this wouldn't have happened, because Apple would've spent more time on getting it right. But that's the problem, Apple has deemed it not worthwhile to expend their hardware engineering resource on such a small volume product.

    So, you outsource, to someone who cares less.

    On one hand, Apple would've made a better 5K standalone display, but on the other hand it'll be vapourware.

    Whilst you're certainly correct, it's nevertheless rather astonishing that this was allowed to happen, either by Apple or LG. It isn't like some fringe case that could easily have gone unnoticed until the hardware was in millions of homes. It seems incredulous that this issue slipped through the net. My view is that it's more likely the problem was known about at launch, but that production were waiting on an engineering fix to come through. But the fact that it happened to begin with shows a rushed development cycle.

    Of course, it doesn't really matter so long as their is now a fix, but it does appear unfortunately amateurish on the part of both parties, and pretty inconvenient if you're an early purchaser.
