Are you doing all this over the air (OTA) and using the TV tuner? If so, your remote will be much simpler if you use different brands. This is a non-trivial set of switching as well, if you want any one of the three to provide audio and want any source on any TV. There are things called matrix switches that can do this, but it might be better to say one of the boxes is for the XBOX, one is for the internet and one is primarily TV.
You will run into the same issue if you are using cable boxes for the various TVs. They will all use the same remote code. You can play games by having one feed from a TIVO with cablecard. You might find the whole thing simpler with a DISH or DirecTV receiver with extender box (Joey).
Thank you for your response.
My sources will be either a DirecTV or AT&T receiver, Xbox one, PS4 or a Desktop computer. If all the TVs are Vizio, is there a way to control the 3 TV's independently (for instance, powering one on without the other two also turning on)? Is there a universal remote that will handle that? I have very briefly looked into the iRule & Roomie, but it doesn't look like they work with Vizio?
Thank for the Matrix idea, I was not familiar with them. After looking at them I think that will solve a lot of problems input wise. However in looking at them, the ones I see max out at 3820x2160 at 30fps. If I am gaming on a computer, I am guessing that will limit my fps. Would it also effect the lag time? One of the reasons (besides the price) that I am going with P series Vizios is because of the fast response time for gaming, so I would hate to negate that feature by using a matrix switch.
If I go with DirecTV and get a dedicated receive and an extender, will the remotes for each control both at the same time, like a vizio remote would control all 3 tvs?
