Remember the LG UltraFine 5K Display that Apple says was specifically designed to work with the New MacBook Pro and as a replacement for the Thunderbolt Display? Well apparently it wasn’t designed to work next to routers. According to 9to5Mac, the 27-inch monitor is useless when it’s within two meters of a router, as the UltraFine 5K Display will flicker, disconnect, or freeze computers due to electromagnetic interference.

In emails to 9to5Mac, LG acknowledged the problem — which LG says isn’t an issue for any of its other monitors — noting that routers “may affect the performance of the monitor” and that users should “have the router placed at least two meters away from the monitor” to avoid issues.

Once the monitor was moved into a different room away from the router, 9to5Mac says the issues subsided.

Despite the fact that it’s insane to require a router to be far away from what is likely the main computer in your home, there’s been no indication that LG is working on a fix for the issue, which may be more troublesome. We’ve reached out to LG and will update if we get a response.
