Tripp Lite B130-202 allows you to extend two 1024x768 VGA video signals up to 500 ft., over ordinary Cat5e cable, from a single VGA source. The Transmitter / Receiver kit also features two local VGA HD15 ports, supporting a total of four VGA monitors ( 2 Local and 2 Remote ). Compatibility issues can occur when EDID information is not properly communicated between the source and the display. The B130-202 includes an EDID copy feature which stores a monitor's EDID information in the transmitter and sends it to the source, ensuring optimal compatibility. Supports all operating systems, and is plug-and-play...no software or drivers required.
