Re: Same story as with 4k video displays
When I finally bought our first 1080p TV, during the initial 'critical viewing' phase that goes with a newly purchased TV, I noticed quite a bit of diffraction on some of the high contrast scenes. It was very annoying, and it took me a few days to find the cause.
After I trimmed my eyelashes a bit, the picture quality snapped into sharp, diffraction-free focus.
There's a lesson in there somewhere.
