Monitor – Windows 10 Driver Issue



Blank Screen, No Video, Flashing Screen

Topic overview icon  Abstract

Further to upgrading their CPU to Windows 10 Operating System some customers have been experiencing difficulties getting their LG monitor from working properly. Surfing the Internet seeking answers to this unfortunate situation we have noticed many third party sites recommending downloading latest driver from monitor manufacturer.

Most LG monitors are Plug’n’Play… which means they do not require any driver! As long as they do not get categorized as “Generic PnP monitor” by a Windows 10 PC. If it is your case, scroll down to the Device Manager screenshots below where an expert assistance LINK is provided.

Should your LG monitor defy conventional native resolution such as LG UltraWide models, some boasting 2560 x 1080p resolution, others 3440 x 1440p, all offered in 21:9 aspect ratio, driver updates will be required from time to time to allow proper communication between CPU and the screen. These driver updates are located in the Support section of LGECI website under respective model’s page.
