Monitor is a 19” widescreen, doesn’t quite fill the frame. There’s two approaches people seem to take either a monitor that completely fills the frame or having a monitor just as a section of the mirror.
Back picture below, it shows a pi3 in there at the moment as I was playing with some of the more processor intense plugins that tbh don’t add much so the pi0 will be going back there shortly.
There’s a good forum at the magicmirror site.
Another tip I’ve had is to use laptop screens and buy a hdmi driver and psu for it.
This would get you a 15.6” screen for around £30 and the hdmi driver for around £25
Bit more expensive and smaller but much less challenge mounting and holding the weight in the frame.
My next one is a 22” monitor which has vesa mount on the metal body itself so I will mount the monitor then build a frame around it which saves the frame having to take the weight of the monitor
