How to use

Connect the VE811 transmitter to the HDMI output of your source device and the receiver to the display's HDMI input. Use a single Cat5e/6/6a cable (or ATEN 2L-2910 Cat 6) between transmitter and receiver. For 4K transmission, ensure cable quality and keep the cable length within 100 m; enable Long Reach Mode if you need 1080p extension up to 150 m. Power both transmitter and receiver according to the supplied power adapters and verify EDID/CEC settings on connected devices as required.

Recommendations

For best results with 4K signals, use Cat6a or high-quality Cat6 cable and keep runs under 100 m. When extending 1080p at maximum distance, enable Long Reach Mode and use shielded Cat5e/Cat6 where possible to reduce interference. Test source and display EDID settings after installation to ensure correct resolution and audio passthrough.
