LG fixes 5K UltraFine monitors to shield them from WiFi routers

LG's new UltraFine displays would fail when placed within 2 meters (~6 feet) of a WiFi router. LG has stated they will add additional shield to all future units to correct the problem.
Sam Medley,

When you drop $1,300 dollars on an external monitor, you’d hope it would work without a hitch. Unfortunately for customers that purchased LG’s new 5K UltraFine Display, placement matters. Earlier this week, 9to5Mac reported that placing the monitor too close to a WiFi router would result in severe screen flickering. In some cases, the screen would go completely black. Moving the router and reconnecting the monitor would fix the problem.

The root of the problem seems to be a lack of shielding in the monitor. Radio waves from the WiFi router cause interference within the monitor which results in the problems users experienced. Future routers shouldn’t have the problem. After a slew of complaints about the monitor, LG issued an apology and stated that they “are committed to delivering the best quality products possible…. All LG UltraFine 27-inch 5K displays manufactured after February 2017 will be fitted with enhanced shielding.” However, current monitors may still be susceptible to the interference. LG has said that “customers continuing to experience issues with their UltraFine displays are advised to contact their nearest LG customer center for prompt service.”

The LG 5K UltraFine is currently on sale through Apple’s site for $974 until March 31st.

After graduating college with a degree in Mathematics, I worked in finance and banking a few years before taking a job as a Systems Analyst for my local school district. I started working with Notebookcheck in October of 2016 and have enjoyed writing news articles and notebook reviews. My areas of interest include the business side of technology, retro gaming, Linux, and innovative gadgets. When I'm not hunched over an electronic device or writing code for a new database, I'm either outside with my family, playing a decade-old video game, or sitting behind a drum set.
