Need help with design/dimensions

[sulaimn2]

I have the following equipment with me

a 12 x 12 inch two way mirror (Vanity vision, 1/4inch thick)
a 13.1 x 8.2 inch screen

What’s the best way of going about this? I have a glass cutting tool and I am thinking of cutting the mirror down to 12 x 8.2 inches. But when it comes to the frame, I would need something that would fit a 13.1 by 8.2 inch screen. I don’t have access to too many hardware tools so making a custom frame is going to be difficult if I want to fit the 13.1x8.2inch screen. For those who made pretty looking frameless mirrors, how did you guys do it? Or basically how did you make it mountable on a wall?

The other option would be for me to get a 12x12inch shadow box that can fit the mirror easily, and buy a smaller screen like this

which is a 9 x 5.8 inch screen and I can fit everything inside the box.
