It’s to bad I can edit my post (reason: Error - You are only allowed to edit posts for 2 hour(s) 26 minute(s) after posting)
Otherways I could check if you/I need to specify the pixel height and width.

Not sure if this is the correct location on the forum to ask this, but I give it a try.
I have recently build a Mirror for my own and with great pleasure. Even better is that there are other people making add-ons/plugins/remote etc.
The thing is that that I’m not sure if I have choice the correct monitor and glass. Can you let me know: how did you selected your monitor/glass, how the finished result looked to you and what you think about my visibility off my mirror?

Monitor was: Mirai 419w210 with 6mm glass (from the Netherlands)
English spec and Dutch specificatie.
