> Would a bit of Post-It Note (for minimal adhesion) damage the screen coating if left on most of the time?

Possible, I have one IPS monitor with a spot on screen where the color is pale. I had a post-it note there and I guess something bad happened when I tore it off.

I used electrical pvc tape for many years on my macbooks, no damage but I got tired of them leaving glue residue. Switched to post-its about 10 years ago, works perfectly.

I've never tried them on a matte or coated screen though.

I use painter’s tape for a similar effect.
