LG’s UltraFine 5K Display might be a 27-inch monitor with a massive 5,120 x 2,880 resolution – and a honking price tag to match – but it’s suffering from a serious bugbear after going on sale last month. Namely, the fact that it doesn’t get along well with nearby Wi-Fi routers.
If the router happens to be within 2 meters distance of the display, then the monitor isn’t so “ultra-fine. ” In fact, things aren’t remotely fine, and the peripheral becomes effectively “unusable”, as 9 to 5 Mac reports.
Apparently, users can experience nasty flickering which can turn into a black screen as the router is moved closer, with the tech site noting that the display would keep disconnecting itself from the MacBook Pro it was hooked up to – even causing the laptop to freeze up at times.
LG’s technical support acknowledged the problem, advising to check whether the monitor is near a router, and saying that this could affect the performance of the display.
