LG UltraFine 5K Monitor Plagued by Rookie Design Flaw

[btarunr]

There's "big" trouble for LG, which scored exclusivity on Apple Store for its UltraFine 5K monitor. A critical flaw in the monitor's design makes it intolerant to electromagnetic interference from devices as inconspicuous as home Wi-Fi routers. Apparently, the designers of the display forgot to give proper EM (electromagnetic) shielding for its electronics. When placed within 2 meters of a Wi-Fi router, the display begins to flicker, and when brought closer, the display even blanks out.

As an immediate workaround, LG advised customers to keep the display at least 2 meters away from a Wi-Fi router. Something like this could be tricky in a postmodern workspace such as a studio, where multiple MacPro workstations wired to such 5K displays are connected to the Internet over commercial Wi-Fi, with powerful >9 dBi antennae designed to spread signal to the far reaches of the office. LG maintains in a statement that this issue does not affect its other monitors.

Well at least you will know you're getting a text when your screen starts flashing XD

It's a feature.

The Apple customer reviews are worth a read too:

Such a fail.

Gee LG, how many engineers were needed to come with this ingenious workaround.

Reminds me of the iPhone Antennagate...

Tin foil hat would help here...

But... seriously... such an error? It's bonkers... especially considering the price...

 

[Caring1]

Sounds like they will have to recall all the monitors already distributed and retro fit EMS to them

I was thinking you get a free roll of aluminum foil with every monitor purchase.

Its a LG monitor, they always sell crap for expensive monitors and cut corners in design. Would much rather get an Asus ProArt or Dell Ultrasharp monitor using that same LG panel over LG badged crap.

so when can I get my 5k monitor Faraday Cage cover?

 

[EarthDog]

Oops...

How about a recall...?

Mwahaha, blaming the monitor for MacBook resets, cursor and other graphics glitches. Yup, those are genuine Mac users.

Two. One to suggest the workaround and the second to mock the first for actually making such a derp derp workaround.

For a $1,000 monitor, it is kind of sad that they couldn't spend the extra $1 per monitor on proper EM shielding.

The way that Macs interface with displays, I can actually believe the display is causing the computer to lock up. They talk to each other a lot more than the old VGA days where you just put out s video signal and hoped the monitor would display it.

I fully appreciate how they all stroke their egos with shit anyone can buy. "My 13 inch macbook PRO with touch bar" why not tell everyone what homeopathic BS you shoved up your arse after your coffee cleanse and slimming wrap session.

Macfags. Just tie their hands so they can't talk.

Most PC monitors are merely junks. They never put their best stuff in them. All the goodies are only found in TVs. Good thing HDMI 2.1 is coming so good riddance overpriced pc monitors.

One could argue that having this communication fail resulting in a complete computer failure is a design fault of the Mac. It could also be that since the electronics are having trouble to output the picture its not unthinkable that it also might do the communication to the mac out of spec causing the problem.

I'd be really surprised if the MacBook talks anything but DisplayPort. Probably HDMI, too, but not at 5k res.

How in the world is something like that missed during manufacturing? Or did the engineers miss it? WTF...

Mediocre testing and quality check. Seems to be a recent trend to cut corners for Korean manufacturers.
