I got 2 computers right with their own monitors, but at the same time the computers are plugged into a TV up front above the TVs, i want the TV to display on a button push or something one of those computer screens at a time sorta cloning one of the displays and on button push switches to the other computer. Can you think of a way? it has been boggling my mind. trying to set it up for computer room.

[recovering disk space, attachment deleted by admin]An A B video signal box comes to mind...How are these displays CONNECTED up?  DVI, HDMI, VGA.etc?

Lets just say you are using HDMI for simplicity.  You could then use an HDMI splitter cable on each PC with one cable going to the monitor and the other (one cable from each PC) going to an HDMI switch box which in turn connects to the MAIN display with a single HDMI cable - You would then switch the HDMI switch to pick what display gets fed to the big display.  There would also be similar splitters and switches for other types of connection.

Just BEAR in mind that if these screens are different resolutions then the display will be set to the highest resolution both monitors support so you may end up running one of the monitors at a non-optimal resolution. Quote from: camerongray on July 10, 2014, 09:37:30 AM
