LG’s UltraFine 5K Display Can Exhibit Issues When Placed Near a Wireless Router 9to5mac.com

Heads-up, LG UltraFine 5K owners: if you’re seeing strange video quality issues, try moving your display farther away from your wireless router. Zac Hall of 9to5Mac explains:

Right out of the box, UltraFine 5K Display was hardly usable as it would consistently disconnect and even freeze my MacBook Pro which made it unusable for work on Thursday and Friday. Connecting it to my MacBook Pro consistently resulted in needing to reboot my machine to continue working.


Support responded by recommending I use the monitor away from a router as they can cause performance issues with this monitor.

I’ve never heard of this affecting the 27-inch Retina iMac, the panel of which is likely shared with the UltraFine display. My guess is that LG’s display is inadequately shielded, and the resulting problems could be a deal breaker for anyone living in a smaller apartment or working in an office with an inflexible layout.

Update: The reviews of this display aren’t good, with some users reporting issues with their wireless keyboards, various video problems, and lots of kernel panics. For a thousand-dollar display ostensibly designed in tandem with Apple, that’s pretty dreadful.

Worse still is that support is via LG, not Apple, so you can’t simply bring this display into your local Apple Store.
