Tripp Lite B130-202A allows you to extend two 1024x768 VGA video signals + stereo audio up to 500 ft., over ordinary Cat5e cable, from a single VGA+Audio source. The transmitter / receiver kit also features two local VGA HD15 ports, supporting a total of four VGA monitors. Compatibility issues can occur when EDID information is not properly communicated between the source and the display.
