Don't most things you'd want to use this with come with remote control mechanisms? Chromecast, Apple TV, whatever you run on your raspberry pi, etc.

TL;DR:

- If you want a certain display tech (qled, oled, ...), you don't need this guide.

- otherwise: there is no difference. pick whatever screen has the size and ports you care about.

I expected something like distance (several m for tv, .5m for monitor), but that goes unmentioned. I guess size+resolution already cover this.
