These already exist and they work at a distance. The screen display is 
produced by a string of bytes sent to it serially by the video card. 
Because it repeats at a known frequency it is easy to pick out from all 
the other random electronic noise. It is a simple matter to detect the 
signal and redisplay this string of bytes to see exactly what is on the 
screen.
