LG admits its new 5K monitor has performance issues

Electronics giant LG has confirmed that its new premium-priced computer displays experience “performance issues” when placed near a wi-fi router. The LG Ultrafine 5K monitor costs almost 900 pounds and is promoted as an external display for Mac devices.

But customers noticed the display flickered or switched off when placed near a wi-fi router and some users posted negative reviews on Apple’s website.

LG has told the BBC that customers should change the location of their display.

“Monitor arrived today and the picture flickered on or off when using with a brand new Macbook Pro,” wrote one reviewer.

Another affected user added, “The device is not properly shielded from wi-fi radiation, so you can’t have a wi-fi router within two metres of this display or it will go black.”

In a statement, LG apologised for any “inconvenience” caused to the customers.

“Changing the location or positioning of either the router or the display should resolve the issue,” it said.

It also added that any Ultrafine 5K monitor manufactured from February 2017 will have “enhanced shielding” to protect the device from electromagnetic interference, while customers experiencing persistent problems should contact LG.
