PURPOSE HDBaseT extenders typically transmit up to 40 meters (131 feet) at 4K resolution, or up to 70 meters (230 feet) at 1080p when using standard Cat6a cabling.
Ensure your source resolution is set properly (try 1080p or 4K30), set a standardized EDID using the DIP switches, and remove any patch panels or punch-down blocks from your Cat cable run. Additionally, check that your HDMI cables are verified for 4K bandwidth.
You can reach PURPOSE AV support by emailing support@purposeav.ca or by calling their toll-free number at +1-888-470-2211.
The RS232 ports on the PAV-EX40 units use a null modem pinout. Ensure that your connections match the correct Tx, Rx, and Ground terminations to pass bidirectional control signals properly between your devices.
