What people are saying
Rated 5 out of 5 by from Works great Monitor is great. Nice appearance. Great performance. Very satisfied.
Date published: 2019-05-02
Rated 5 out of 5 by from Life changing monitor I have been using this for a couple of weeks now. I can't believe how much more efficient this is than having two large monitors. Being able to work "in the middle" and use the sides for additional space is really a game changer. I have no idea where the speakers are, but they too are great and allowed me to eliminate the speakers off my desk. Finally the resolution and refresh make this monitor very easy on the eyes. My only criticism is that the instructions are less than optimal. An online video on how to set up and use the monitor would be great. I think I've figured it all out, but there may be an even better way. Not sure how I would find out.

Rated 5 out of 5 by from Amazing monitor!!! I have used 2 monitors forever and was a bit leary to go down to one, but now I'm kicking myself for waiting so long! Well actually, I think waiting gave me a much better product! I truly love my 34 inch ultra wide display from LG. I reviewed a bunch from all the usual vendors and decided on this one. Amazing quality and I think an amazing price for the quality as well. Wouldn't go back for anything now! If you're still holding onto 2 monitors or was considering a smaller UHD version, consider this ultrawide model. Muliple windows for Windows is a snap. Graphics are awesome. I'm not a gamer, but an old IT guy and this is GREAT on the eyes.

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.

As Jordan said, You can only overclock monitor above 60 with AMD. If you do with Nvidia, there will be frameskipping.
