So, I choosing my first gaming monitor (QHD, IPS, and better Hz, mid/low price)
Right now testing on Acer Nitro XV322QUKVbmiiphzx
And after doing UFO tests i find monitor is softly flickering while it on same resolution and update rate, and i'm not sure if its still flick after switching to another resolution/rate, but its back as I switch resolution/rate back.
Flickering dissaper after some time, about 10-20 minutes.
Monitor power restart, or PC restart seems don't fix it.

I found it after pretty short time of "Flicker" and after "PWM" (fat lines).

And its not like just "burn-in", its exactly flicker.

I almost shit my pant, guys!

What do say about that ?

Explanation; see viewtopic.php?t=7539

Some models are more unusually sensitive to LCD inversion artifacts -- and patterns that keeps flickering is one kind of LCD inversion artifact.

TL;DR: This will occur with any software giving you flicker patterns, including 3D software and black frame insertion.
And the fix is, run some solid images for a few minutes.
