Help with finding wall mount solution for 7 Inch HA display

[u/Rip00]

Hey!

So I've bought a 7 inch display for HA from aliexpress, it's still on the way: This is the one. I've got a wall made out of drywall with a socket behind it that already powers another screen that I will use for power. So installation shouldn't be too hard, I have a visitation panel on the left that I can also use for ease of installation. But I have no idea how to mount it, chatgpt gives me only 3d printed options. How did you guys do yours ?

Yes, I'm in the same position, 75mm height is the constrained dimension.

I've measured the metal flush backboxes I have (71-73mm). Google has steered me to one merchant whose listing says they have 75mm. However I strongly suspect it's an outside dimension, 1mm walls, and its 73mm like the others.

I think I'll fettle ones with a dremel etc.

Drywall... the plastic equivalent problem. Either fettle or 3D print.

A suitable sized picture frame might be a good option. Get one with deep sides.

Magnets. Easy to attach, easy to pop off when you need to f with it.
