#Fail: LG’s UltraFine 5K Display Is Useless When It’s Within 2M Of Router

You have to wonder if anyone QA’s their products these days. I say that because this story from 9to5Mac details how the LG UltraFine 5K Display which is Apple’s recommended monitor for their new MacBook Pro notebooks is pretty much useless when it is within 2M (about 6 feet) of a wireless router:

The problem is UltraFine 5K Display becomes unusable when positioned within 6.6-feet of a router. I discovered this issue after purchasing my own UltraFine 5K Display last week and thinking something was defective with my hardware.

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.


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.

Since moving the router to another room, UltraFine 5K Display has remained connected without issue.

I’d bet that other products besides routers will trigger this behavior. Nobody has stumbled upon them yet.

Given the amount of money and time poured into these products, you’d think they’d have done proper EMI susceptibility testing at some point. It’s moderately expensive, but easy enough for LG to afford. But clearly they didn’t do that, and now it’s an issue. If I owned one of these, I’d have to be pushing for them to take it back. Plus, Apple must have some egg on their faces as well seeing as they’ve recommended this monitor as they’re out of the monitor business. Perhaps they should choose their partners more carefully?
