  First, ensure that all devices (source, extender set, and display) are powered on. Then, check the LED indicators on the transmitter and receiver to verify they are normal according to the user manual. Confirm that the picture displays correctly when connecting the source directly to the display. Try unplugging and plugging in the HDMI/Cat X cable, or use a different cable. Ensure the cable length is within the specified transmission range for the resolution you're using. It's recommended to use Cat 5e/6/6a/7 cable, not Cat 5, and ensure both connectors of the Cat X cable follow the same standard (EIA/TIA 568B). Finally, test with other source and display devices to rule out compatibility issues.
