I’m seeking the thinnest, lightest weight displays that preferably have little to no indentations. (Many screens have a backside buldge or something that doesn’t let them be perfectly flat rectangles.)

I don’t have any L x W specifications yet, just looking for the best screen possible for a smart mirror project before limiting to a specific frame size.

HDMI input is a must (because I have no idea how else to show content on a screen from a raspberry pi.)
