27″ 4k monitor
If youâre looking for a 27â 4K monitor, this might be the best option out there. The picture quality is excellent and very pleasing to the eye. Colors look natural. Great for both gaming and content consumption. Iâm really happy with it.

Potentially a great monitor….but
This monitor has the potential to be the perfect work/gaming monitor for those that don’t want to worry about OLED care. I had two problems with it that ultimately made me return it. With the current firmware and Nvidia drivers, there’s some odd issues with my 5080/Windows 11 setup. The monitor would lose signal and reboot when waking from sleep or inactivity. Another person on Reddit had the exact same issue with a similar setup. This will probably be fixed with a future update, but who knows. The main reason I returned it was what I assume is a backlight uniformity issue. The bottom 20% of the screen was slightly darker than the top. The taskbar and the bottom of webpages had dull/muted colors compared to the rest of the screen. It was very obvious on dark backgrounds with white text. Other than the issues above, the monitor has great colors, great blacks (much better than a standard IPS) and HDR looked pretty good in games.

Stay Far Away
What a peice of crap, did this not even go through QA. Works fine in 1080p but I want to use it in 4k, I set it to 4k mode, turn on hdr, and if I launch a 2d game not compatible with HDR the monitor becomes FULLY unresponsive. Amazon should pull this product it literally doesn’t work.

The first of it’s kind, loving it.
Great IPS color, better blacks, clear, fast, smooth, no issues with dp1.4 on windows 10. I’ve read others have 2.1dp possible issues, but there is a setting that lets you change the dp signal inside the OSD so maybe that could be a fix? I’ve had no issues so far. I prefer IPS over OLED due to longevity and brightness, and no worries for burn-in. Loving the 480hz at 1080p even in newer titles.

Really solid 4K IPS monitor
Really good monitor. If youâve had a 4K IPS before, you know what to expect. The 480hz 1080p mode is mostly a gimmick unless you play 8/16 bit games or are super into esports at 1080p. I rarely play games below 1440 though.The monitor gets really bright and the text clarity is really nice since I also use this for work. Only negative for me is the lack of USB-C display input. Other than that it works really well

Great monitor plagued with signal loss issues
A very impressive monitor that has fantastic black levels and astonishingly low IPS glow that is unfortunately rendered almost unusable on the latest Nvidia gpus (I donât have an AMD card to test).On my RTX 5080, the monitor frequently loses signal at odd times (most consistently when trying to play games in full screen). It also has very slow/sometimes unresponsive wake times when booting back from sleep.On my older 1660ti, I seem to have no issues. If I was purely guessing at the problem, I assume it has to be something wonky with DP 2.1 DSC either on Nvidia or LGâs end – given the old display ports on the 1660ti work fine, whereas the 5080 has significant issues.Disappointing because the panel and dual mode itself is quite impressive and unique.
