@gbarranco Any monitor will work that has HDMI input. Here’s the trick though. if you’re gonna put it in/on a wall, use a monitor that has it’s ports pointing down, not out of the back. Make sure if you’re going to put it behind mirror glass that it’s flat - you don’t want a curve on it so it can sit flat against your external glass.

I personally use a monitor like this one: https://www.amazon.com/Dell-Ultrasharp-U2719DX-2560x1440-Resolution/dp/B07KGR784M/ref=sr_1_4?dchild=1&keywords=edge+to+edge+monitor&qid=1615315119&sr=8-4

Notice how the image is edge to edge, that way I can take off the frame and have almost all the monitor used.
