What people are saying

Rated 5 out of 5 by from Telework Dream Bought this fantastic monitor 2 days before being sent home for telework during the COVID Calamity. Couldn't be happier or more productive! We even use the USB charging ports for phones and headsets (nice unexpected touch LG!). You can set it for a variety of split screen configurations so your windows snap into place easily like three across evenly, or one big and one small etc. We have two laptops and a desktop attached that we easily switch between with a little hidden joystick on the bottom rim of the monitor. All great useful stuff. Honestly can't think of a thing we don't like about this beauty and wouldn't hesitate to recommend to a friend or to buy another one if we needed it.

Rated 5 out of 5 by from Outstanding Monitor for any laptop Bought this to have more real estate for doing software development and was floored how easy the setup was and picture quality. I downloaded the driver and clicked on menu to configure the screen. I spent more time trying to decide which screen pattern I liked. The speakers are nice with good sound quality.

I have been using this monitor for a few months now and absolutely love it. I am interested in putting it on an adjustable arm mount that clamps to my desk. Is this possible and if so, what arm mounts is/isn't it compatible with?

Asked by: HanB
Yes. I have 2 of these monitors on Ergotron LX Desk Monitor Arms. They are easy to mount and hold up well. That said, I have one monitor on a big, corner style desk which requires the arm to be fully extended and I notice the monitor shakes a little when I'm aggressively typing ;) Otherwise, for standard use, it works great.

The past 3 days my LG Monitor has no sound after windows update. After each update my LG monitor is not listed as a sound device. After system restore I have sound & it is listed again. When I run driver update it says I have the most update. How do I fix

Asked by: AJMa
Hello AJMa, that doesn't sound right. Please give us a call at 1-800-243-0000 when you are with the unit. ^AC

Can I set quad screen and assign hdmi 1 to the screen 1, hdmi 2 to the screen 2 ? Works that way?

Asked by: Josias
I apologize, but no; according to the chart on page 25 of your owner’s manual, it is not possible to use both HDMI ports, at the same time, for the Picture By Picture (PBP) functions.
