Here I am. After 6 returned monitors (dead pixels, physical damages, color banding), I finally put my hands on 2x LG 27GL850. Ultra happy. Outstanding colors, godly response times. Huge ips glow and a bit of lightbleeding on both, but I am on my 7th attempt for a good monitor so I was like "FML, I am too tired for this, I can probably live with that". 20 minutes looking at the screen and I noticed my eyes are getting drier than usual... "hmmm," I am thinking "maybe it's from that s*tty IPS Dell monitor that I use at the office."
My eyes were gettin more sore with every minute spent in front of the screen. I calibrate it, did research, lowered my brightness to around 25, tweaked settings, created some ambient light, used them during the daylight, tried every freaking possible setting. I got to the point where yesterday, I've played Apex for like 6 hours, and today at work I couldn't even concentrate anymore. Almost blurry vision, migraine, extremely dry eyes, turning a bit red.
This happened after a whole week after telling myself that it's going to get better. It doesn't. I don't understand. Never had such problems. Did 2 visits at the optometrist in the last 4 months. My vision is almost 20/20. I don't even wear glasses. I don't have sight problems. I've used IPS before and had no problems. I had an ASUS TUF VG27AQ that gave me no headaches (had 2 dead pixels and damaged frame). Could it be from the type on panel LG is using? My friend also searched on korean forums saying that a lot of koreans are using the monitor, but nobody is complaining about the headaches. I've seen some people here on Reddit also complaining about it. What in the earth could be going on? On Wednesday my screen protection glasses should arrive, but I am expecting no miracles.
I might have to return them.
Edit: Thank you very much for all the suggestions. I am going to try them out and hopefully things will settle. 6 months ago, before starting building my actual PC, I was told that buying the monitor is the hardest part. Couldn't agree more.
