HDMI split switch

[JayI]

Hi
I have 4 television actually one projector 3 televiaiona and they are currently split to X1 Comcast box
Problem is downscaling
one out of 4 is 720p
Would an automatic switcher work instead and if so any recommendations
All ttelevisions 3D 1080p with one exception the 720p

A simple HDMI switch won't work in reverse. A 4x4 matrix would allow you to select which TVs were connected. When the 720p TV is not selected your would get 1080p.

Not sure it is worth the bother unless Comcast has 1080p channels. Usually they are 1080i or 720p. 720p is better than 1080i for anything with motion so I set my cable box to output 720p.
