The Atlona passive VGA transmitter unit allows sending a perfect video signal over 1 x CAT5/6/7 cable up to the distance of 330ft with resolutions up to 1280x1024. These extenders can be mixed and matched with each other. The wall plate transmitter can be matched with "box" receiver and the other way around and of course, the wall plate transmitter will perfectly work with wall plate receiver and "box" transmitter with "box" receiver.
Plug and Play, no drivers or software needed, user will not even notice the difference when using an extender versus a direct connection. The extenders require no external power.
