Higher resolution displays make it harder to pixel peep because 100% pixel view covers a smaller area of the screen.
Exactly!
If you had a 36MP FF image on a 33MP 8K screen, hitting 100% would only enlarge the image a few percent. If you hit 100% on a 36MP image on a 2MP 1080p screen, it enlarges the pixels several hundred percent.
I think there are cognitive dissonances because way too many people are hitting the 100% button on high megapixel images while using 2 MP 1080p screens. I have a 14" 4K laptop. And several 24" 1920x1080p monitors on my desktop machine. Many images that look horrible at 100% on a 24" 1080p monitor look perfectly fine at 100% on my 4K laptop. (I'm shaking out Topaz A.I. Gigapixel and now have images up to 96 megapixels to dissect.)
I also detect cognitive dissonance when I use "PPI" when posting about monitors.
I hope 8K monitors are more reasonable when I update my Win 7 desktop to a new Win 10 machine. I feel constrained because my highest resolution monitor (my 4K laptop) is only 8 megapixels. It is 320 PPI though.
