That $1300 5K LG Monitor Apple Sells is 'Unusable' Near WiFi Routers

LG Ultrafine 5k Display

Sporting a modern design, the LG UltraFine 5K features a IPS panel with a resolution of 5120 x 2880, packing a whopping 14.7 million pixels into the 27-inch display. The company claimed the monitor was especially made for connecting the new MacBook Pro laptops to a bigger display. For some Mac loyalists, the new monitor is the closest thing they can get to a Thunderbolt Display alternative.

However, it turns out that the LG display shares Apple's philosophy about networking and playing nice with other. The UltraFine 5K appears to be a fine monitor, as far as it goes, but it suffers from one critical problem - it dies if you put it near a router. Apparently the UltraFine 5K Display will flicker, disconnect, or freeze computers due to electromagnetic interference.

I moved my router from the office to the living room and tested UltraFine 5K Display with my MacBook Pro on my desk and found that it stayed connected in this spot for the first time.

Taking a quick look at customer reviews for this monitor on Apple's website reveals that quite a few people with this monitor bought it with the intention of using it in close proximity to a wireless router.




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.

There's no word whether the problem can be solved and LG has stated that this is an issue exclusively for the 5K UltraFine. Without ample proliferation of 5K Displays on the market, it's hard to test whether this is an overarching problem tied to all 5K displays, or just LG's hardware mishap.

A support rep for LG Electronics confirmed that the 5K monitor can be adversely affected by a nearby wireless router, and said that the issue doesn't affect any other LG monitors.

Until then, if you have a malfunctioning UltraFine 5K Display, consider moving the router away and see if it functions properly afterward.
