~105 vs ~83 PPI will make a difference no matter what.
To me the biggest difference is if you use DLSS, since it's a ratio based on the native resolution of the display. The main reason people complain about it on 1440p displays is that the render resolution of "DLSS Quality" is lower res than "DLSS Performance" on a 4K display.
But does 83 PPI vs. 105 make a noticable difference while gaming on OLED with HDR and everything enabled?
Yes, I understand the low PPI and low resolution kinda sucks for desktop use in Windows and Office work. Yes a higher res would be better on this monitor for that.
But in games, am I missing something with this 83 PPI? Games look amazing and beautiful and stunning as they are. Or would a 4k display give me even more details and a crisper image?
