It hurt my eyes. It was a personal problem, one that I'm still trying to figure out, as it was confirmed the panel did not utilize PWM (it didn't flicker). The color temp and brightness wasn't bad either. I'll probably be starting a thread on the subject to gather advice, but I have an eye doctor appointment tomorrow.
My personal stuff aside, the monitor was pretty good. It didn't look cheap, and it didn't have any outstanding issues worth mentioning. I believe seeing a tiny bit of backlight bleed, but that was about it. Input lag was good, colors were good, pixel density was obviously very good for a computer monitor of that size at the time that I purchased it, etcetcetc.
