Are you routing via Cat5 yet? Well, if not, give this a try: Extron Electronics announced that the MTP R 15HD RSA D is now shipping. The new Decora mount twisted pair receiver accepts VGA, RS-232 control signals, and mono audio over a single UTP cable. It is compatible with resolutions up to 1920×1200, and will support cable runs of 600 feet (185 meters) or more with XGA signals, and 450 feet (135 meters) or more with UXGA signals. It also offers separate continuously variable level and peaking controls to compensate for signal loss over long cable runs.
Extron specifies that the RGB bandwidth is 350 MHz (-3dB). It’s also got selectable gain and peaking, and active PC audio buffering. Selectable stereo or dual mono audio output allows for a choice of stereo audio or actively summed L+R mono audio on both outputs.
