I want to set up a video wall at my place that can stream independent sources or combine into one image across all 4 screens. I can buy a 4x4 matrixer but the issue I think I am going to come across is remote controls. The TV remote is going to control more than 1 TV (e.g. I want to turn TV "A" off but TV "B" also turns off), and similarly if I use something like a Roku stick for the HDMI inputs on the matrixer, the Roku remote will control more than 1 stick. Any suggestions on how to approach this? CPU with 4-HDMI output and use separate windows for streams?
