Here’s a Temporary Fix for Your LG UltraFine 5K Monitor if It Continues to Give You Problems


Earlier, LG’s UltraFine 5K display was suffering from numerous issues while it was connected to the 2016 MacBook Pro’s Thunderbolt 3 port. It was later found out that the monitor was suffering from this because it was in close proximity of a router. Though the following isn’t the most practical of solutions, here is one way how you can continue using the 5K display in the same room.

LG’s UltraFine 5K Lacks EMI Shielding and Must Be Kept 2 Meters Away From Routers to Work Flawlessly

While there was no teardown initiated, it looks like part of the problem why the LG UltraFine 5K display is unable to function is due to lack of EMI shielding. Another reason according to Ars Technica is that a part of the monitor is probably oscillating at a harmonic of Wi-Fi (2.4GHz or 5GHz) radiation and the likely culprit is a faulty Thunderbolt 3 cable that’s bundled with the monitor. It is possible that both Apple and LG work tirelessly to ensure that the next batch of 5K monitors do not suffer from this issue, but so far, we have heard nothing from them.

So what exactly is the solution? If you cannot move your current workspace that comprises up of the 2016 MacBook Pro and the high-resolution display, then your only other option would be to maintain a distance of 2 meters from the router and the monitor. While this is not the most practical of solutions as stated above, a better idea would be that instead of moving the entire workstation, you can position the router in an area where the signals do not interfere with the display’s normal workings of the day.

In this way, the surrounding area will also be bombarded with wireless networking signals and you are free to carry out your extended screen real estate as you had intended to do so earlier.
