Entire rig crashes on 1440p monitor

I have a really specific problem. Game runs completely fine on 1080p monitor but crashes my entire pc on 1440p (iiyama G-Master G2766HSU-B1 RedEagle 27"). Seems to only happen within breaches and "willow" map. Additionally right before the crash all temps and usages seem to be normal and not spike. I checked everything:

BIOS reset
tweaking everything in game graphics options
checking my rig for any malware
even hard format and starting form clean pc with only steam and poe2

Still game crashes on this one specific monitor and in those circumstances
pls help
