Last week, the LG UltraFine 5K Display ran into an issue that would cause its monitor to glitch when placed near a router due to a radio interference problem that would render the display useless within two feet of connectivity gear, hanging the connected MacBook Pro as a result.

LG found a solution by redesigning the UltraFine 5K monitor so that it can now manage being placed near a Wi-Fi router. Additionally, the interference problem no longer affects units produced after February since the company included enhanced shielding in the the monitor. If you previously purchased an UltraFine 5K Display, however, you must contact LG’s support team for help.

The UltraFine 5K Display is supposed to be the best companion to the 2016 MacBook Pro, but the need to equip the device with enhanced shielding seems to uncover hardware flaws in UltraFine 5K Display’s electrical system. More specifically, reports claim insufficient isolation in the monitor’s electrics.

Fixing the interference problem

After the problem cropped up last week, LG has now advised its customers to just place the monitor two feet away from a router. The solution is not practical in all instances, though. LG stated:

We have been made aware that the LG UltraFine 27-inch 5K display (model 27MD5K) may experience performance issues caused by signal interference when a Wi-Fi access point is positioned behind the display within a distance 2 feet (0.6 meter). Changing the location or positioning of either the router or the display should resolve the issue. Customers continuing to experience issues with their UltraFine displays are advised to contact their nearest LG customer center for prompt service. LG apologizes for this inconvenience and is committed to delivering the best quality products possible so all LG UltraFine 27-inch 5K displays manufactured after February 2017 will be fitted with enhanced shielding.

It remains to be seen whether the solution does fix the issue. Share your thoughts!
