Hi all, total noob here. I'm trying to build a new home theater. I want to connect multiple cable boxes/receivers so that one large TV can show several programs at once in a split-screen format. Like 4 football games at once, each in one corner of the TV screen.
I can't find an easy way to do this. Does it require a video mixer with hdmi inputs? I found a few online, but they are expensive, like Blackmagic ATEM or Roland systems). I was wondering if there is an easier way to do this.
Thanks in advance!
