You can solve the problem in two ways:
1) Use an interface extender like this one . Transmitter, receiver, between them - a twisted pair. Consider that you have received a VGA cable up to 250 meters long.
2) Transmit video over an existing network. To do this, you need a streamer, like this one, which will convert the analog signal and act as a video server.
In both cases, you may need a splitter if you want to display the signal on a monitor near the computer and transmit somewhere else.
