Beautiful Screen for Gaming - This is an amazing monitor for 4K gaming, especially paired with a PC with a good graphics card. Paired it with a RTX NVIDIA 5080 and it can easily handle 4K game resolutions with high refresh rates. I had the same LG monitor model with 3440x1440 resolution prior to this, and that one is amazing also, but since it can't handle 4K at full resolution, I decided to upgrade with this one, and I'm more than happy I did.

Just do it - I have owned this for at least a year and so far have not had a problem with it. It runs HDR through a 5080 oc like hot butter. Smooth. It has tilt feature and can lower it or raise it. I have never had any problems with balancing it, the stand is solid. I can play anything easily at full resolution and rarely use the DP side because the HDMI is so smooth and good looking.

Beast of a monitor - If you have the desk space and want high refresh rates at high resolution you'll love it. I've heard complaints of bloat ware but haven't experienced it myself.

Zero Picture Quality - I arrived home so excited to set up and use my new LG monitor. I set it up and wow did she look great. Plug it in and nothing. I check everything and its the monitor i does not work. Talk about a let down. So I packnit up and head back to Best Buy to return the monitor. Surprisingly it was fast and easy. But they didnt have any left so they upsold me another LG that cost an additional 700 dollars. I was chasing the excitement at this point hoping i would be able to be excited again. Unfortunately this is were all the problmes began.
