About what 1 pixes do you say?
Area of magenta pixels from the top of screen (I'm looking at 90 degrees, not from a side), waiting for replacement, and for testing of next unit by the shop, before sending it to me.
Background light from both sides is really bad, looks like a little dark strips. (similar to CRT-effect)
Black color is not really black one, it is a dirty-gray.
From all the defects apart from magenta area on the dark backgrounds
I could suffer, they are not so critical.
But apart from these defects monitor is simply super.
FreeSync works fine, adds extra ~10 fps, stable 2k 70 fps in the games with RX480 nitro+ 8gb, really, no glow effect, no input lag, I kill more enemies now with this screen, and picture looks fantastic.
Colors are fantastic, has good predefined profiles.
I bought it for both: gaming and development, for both purposes it is fine, but good unit is needed.
In the case of second bad unit I'm going to take Asus mg279Q. I do not need it's 90\144 Hz, and it is from 2015, but there is no choice from this kind of monitors in our stores.
Who had mg279Q - please let me know...
I simply cannot believe now that supplier can provide a good unit of this monitor, will let you know if yes.
Verdict: If you have any Freesync RX4..\5... card - this monitor is for you, but check it good in the shop and don't buy it from the Internet !!!
And I agree with other guys from this forum, overall quality of big IPS screens is awful, not enough competition, Chinese brands, where you are?
Today got replacement, 1 dead black pixel, but with this I can live.
