Review on LG 27GN800 B Ultragear: Response Compatible 2560X1440P, Flicker-Free, Adaptive Sync, HDR, Anti-Glare Screen | Review & Buying Guide by John Bayramdurdiyev

Basically, I'm happy with the monitor. I don't feel like my IPS transmittance is that bad compared to other monitors I've had. For resolution and frame rate I use it. But my goodness, the anti-reflective coating is a maintenance nightmare. It is an absolute oil magnet. So if you try to scrape off a stain and hit it with your knuckle, you'll end up with another stain. DO NOT USE GLASS CLEANER OR 99% Isoalcohol. It leaves horrible residue (I wouldn't use any harsher product at all). It will rub off. But use the purest water you can. I've learned to clean mine with deionized water and lens paper. I randomly get a notification that the monitor is going to sleep because it doesn't detect any input or the VGA MOBO LED is on. But in fact it causes no problems and has no problems.
