This HDMI over CAT6 extender lets you transmit your 4K 60Hz signal up to 165 ft. (50 m) over a single CAT6 cable, with the added benefit of a local HDMI output. The extender supports High Dynamic Range (HDR), providing high contrast images with enhanced video.

Astonishing 4K Picture Quality

This HDMI Ethernet extender supports a 4K 60Hz (3840 x 2160) resolution, providing four times the picture quality of high-definition (1080p). The extender supports HDMI 2.0 capabilities, offering 4:4:4 chroma subsampling. This ensures a crystal-clear picture that's ideal for delivering video content. With HDR support, you can enjoy increased contrast, color brightness and greater luminosity in your images.

Long-Distance Transmission

Extend an HDMI signal to up to 165 ft. (50 m) with the HDMI to CAT6 converter. Use your existing CAT6 cable infrastructure with a direct connection to the converter for an easy run through walls and ceilings, saving you on installation costs.

Compatible with HDCP 2.2 Devices

Connect your HDMI 2.0 devices and displays with confidence, knowing this extender is HDCP 2.2 compliant. This lets you harness the capabilities of HDMI-enabled devices such as Blu-ray players or online streaming devices in higher resolutions. It is also backward compatible with previous generations of HDMI and HDCP.
