Thank you for your reply.
So I propose to create a mirror with 2 vertical screens and 1 raspberry pi 4. There will be no message in the middle, but just on the sides.
For example weather forecast, traffic, calendar and some information on the left screen ; and Spotify, RSS feed on the right screen.
The idea is to “recycle” 2 screens of 24 inches to make a big mirror.
But the screens will not necessarily stick together, there will be space between them. If you have some examples on the method or the files to modify let me know
