I'd like to recommend and excellent site that shows
full details about your screen resolution and other
technical characteristics:

https://www.mydevice.io/

It's indispensable for web app development, but it's
also quicker than going to your device's Display Settings
when you need to check things. I have it bookmarked on
my phones, tablets, PCs.

My two screens are 1920px and 1680px, and I keep forgetting
or mixing them up, so this comes handy.

By the way, this could be a possible reason for my ZTree
crashes when moving sessions around.
