here is official specs for this monitor:

i bought this ultrawide monitor few days ago and tbh it destroyed me much more than anything before.
biggest problem with my eyes i have when i move my head and perspective even few centimeters and it have different image and it kills my eyes so much. sometimes i have feeling like im looking at shining crystal or something like reflective stripes, weird feeling
ironically i had no problems with this screen when i was looking from huge angle like 70 degrees at screen and screen was illuminated regurarly not when i look from center and in center its darker at edges its brighter and when i move i feel huge eye pain like someone is cutting my eyes with saw

i saw article which tells a little bit about problem i have so i probably think its gamma shift problem?

question is, is it fixable or should i return it because no matter what i will no fix it and its not fixable?

here is video i took with this panel with camera from phone:

you can download for better quality because player shows only 360p

as you can see at the end camera shows vertical black stripes, does it mean its flickering? i was using there 100% brightness at monitor so its weird
and also when i move camera closer to screen it have something like black ring and when i move camera on screen this ring also moves. maybe thats what kills my eyes?

let me know and tell everything because i need so much help to understand this panel, thanks
any idea how to fix it? or maybe i have astigmatism that i dont know about? but last time when i was at optometric they said i have 0.5 and 0.5 is not necessary to wear glasses and a lot people have. i also have miopia -3 at both eyes

no idea what to do guys i need your knowledge so much
