Hi ,
Yes, it is doable. I added a sample video as reference.
The easiest way to add videos is to go to Library > Material > Videos.
Add the 'Video sample' material to your TV screen.
Then, in the material detail change the video from the viewport.
Repeat the same action into your second screen and add a different video file.
I hope this helps, if you have any further questions please let me know.
Cheers,
Francesco
