degen Yea, I tried the Benq XL2411P but it wasn't ok for me. Anyway, I think it's not just a monitor problem but a combination of display, OS and GPU drivers. Because now I have some problems also with my Alienware 240hz display.. next week I will do a clean install of Windows 1709 and I will see if my problem will be fixed.
This is the list of the monitor I tried two years ago:
BenQ V2400W: It was my first full HD monitor and i think it's a CCFL monitor. I bought it over 10 years ago. No issue with it, I want to try to use it with my actual setup and windows 10 1909 and see if it's still ok or not. Next week I'll try it.
LG 27UD68 4K 27" IPS LED. With this monitor, I had the first symptoms. Redness in the eyes, headache, etc.
AOC I2481FXH FULL HD 24" IPS LED. Same symptoms.
Asus MG248Q FULL HD 24" TN 144hz. It was ok but I didn't like the monitor itself. Really bad colors.
