How to use

Ensure cable lengths and quality match the desired resolution (for 4K use shorter or higher-quality cables, up to 25 m recommended). No external power is required; once connected the device will pass the HDMI signal and EDID/HDCP information between source and display.

Recommendations

For reliable 4K performance, use high-quality HDMI cables and keep individual cable runs to 25 meters or less. For extensions up to 40 meters at lower resolutions, verify cable quality and test the setup before final installation.
