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.

Amazing product! have to se to believe. awesome professional response.
Worked well for the first 6 months, then decided to stop displaying anything. Would not recommend this product. LG support is not helpful and will need to repair at your own expense.
The monitor seemed to have great picture quality for an IPS, but I wasn't able to find one that didn't have some kind of QC issue. Your luck may be better, and I hope it is. The only real complaint I have about this monitor is the 1080p/480hz mode. It doesn't have integer scaling, which makes no sense because 4k is an integer scalar (2x) of 1080p. The end result is a blurrier image than necessary in the 480hz high refresh mode.
Probably the best monitor I’ve ever owned. Runs a tad hot. But that was to be expected. Easy to set up. The DP 2.1 made this monitor worth the price. Running games between 150 and 300 franes per second now. Wish I had bought it earlier. Works great with my AMD rx 9070 xt oc, and my nvidia 5070 to oc 16gb
Es un muy buen monitor y muy rápido pero al las 300 horas de uso le salió un pixel congelado y 1 o 2 sub pixeles no se nota mucho ni quiere lo uso pero eso no debería pasar para un monitor de ese precio pero de ahí en adelante es uno de los mejores monitores que e probado
Really good monitor. If you’ve 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
Quality control is a major issue. My first unit had two visible lines on the right side of the screen, which were particularly noticeable against a white background. My second unit had two dead pixels right in the center of the display. It’s a shame because, technical flaws aside, the monitor offers a great balance for general office work and occasional gaming. It is definitely worth the money if you can find it on sale for under 500, but be prepared to check thoroughly for defects.
