GSYNC and eye-strain?
Posted: 01 Jun 2014, 21:29
I apologize in advance if this question has already been answered, but I can't seem to find a solid answer anywhere.
TLDR:
Since the GSYNC upgrade gets rid of the PWM dimming, does that mean people who suffer headaches/nausea/migraine issues using the Asus VG248QE monitor will have those issue disappear? Since the DIY kits are back in stock, I'm really wondering if I should get one.
Long version:
I hadn't realized that I never used a PWM-dimmable monitor before (nor did I know this monitor used it, or even what PWM dimming was for that matter), and I didn't really have issues with my VG248QE until I was gaming one night and it was just too bright. Turned the brightness way down, and over the next 3 hours I slowly developed issues that gave me extreme eye pain, a migraine-esque headache like I've never had before, pretty bad light sensitivity, and was sick to my stomach so bad if felt like I was being slammed by a kickboxer ever time I breathed in. Oh, and my left eye started twitching, a lot, even when closed in a dark room. Not fun.
And it came on so slowly. It wasn't until I stood up after those few hours, and prompty fell down, that I realized I had a major problem. Like a live lobster being boiled slowly, I swear. And this lasted for 3 days, without using my machine any further.
So after some research, I tried resetting the monitor and removing anything I've done that would've caused this change. But I can't shake it now. Even just sitting in Windows looking at my desktop, I have significant eye strain. I set it to strictly 100% brightness so the imperceptible flickering should be gone, but either it isn't or the brightness alone gives me headaches. I tried a bunch of things, including the LightBoost hack in case it was a sensitivity-to-blurring issue... and while it was different, it was not much better. Now I had blotchy black spots in various parts of my vision, which increased 100 fold whenever there was a significant amount of white onscreen. So I abandoned that.
Found this post, which had a solid tip to set brightness to 100%, and lower contrast and colors to get the brightness down (at a sacrifice of color quality). Even better, I turned on my CFL lamp next to my monitor as suggested and this improved things further.
But the colors are so awful now, and my eyes are still recovering. So, what I'm wondering is, has anyone with issues like these claimed significant improvement after using the GSYNC mod? I'm a fan of the tech since I read about it here on blurbusters (no stuttering, no tearing, and no input lag? sign me up!), and I already use only the displayport input anyway... but if it is going to have the same eyestrain or worse issues that may put me in the hospital... it just won't be worth it.
Any insight you guys might have would be greatly appreciated!
