I want to set up a pc with dual screen, one being a monitor in the computer room, and the other being an lcd tv in the adjacent room about 40 ft (cable wise) away.....i want to be able to have a keyboard and mouse in each room and switch to either display and set of user imput devices when needed to control the main pc in the computer room. .....so basically im asking is how to get a video, keyboard, and mouse signal with 40 ft of cabling and if possible some way to switch between sets of keyboard and mice. I appreciate any input or suggestions you might have.
