With HDCP 2.2 compliance and support for HDR formats, this extender is ideal for conference rooms, classrooms, digital signage, and home theater systems that require reliable long-distance HDMI distribution.

Supports 4K UHD with HDR and HDCP 2.2

This HDMI over CAT extender supports 4K/UHD resolutions at 24, 25, and 30Hz with 4:4:4 chroma subsampling, as well as 4K/UHD at 60Hz with 4:2:0. It is HDCP 2.2 compliant, ensuring compatibility with protected 4K content sources such as streaming devices, media players, and Blu-ray players. HDR and 3D formats are also supported, delivering enhanced contrast and immersive visuals across extended distances.

Extended Transmission up to 150 Feet

Using HDBaseT technology, the KD-X222PO transmits high-resolution video and audio signals up to 150 feet with a compatible shielded Cat6a cable. When using standard Cat5e or Cat6 cable, it supports distances up to 125 feet. This capability makes it suitable for large rooms, commercial spaces, and installations where source equipment is located remotely from displays.

Advanced EDID Control for System Compatibility

Integrated EDID management allows installers to control and optimize communication between the source and display. This helps ensure stable handshakes and proper resolution matching in complex AV systems. EDID control is especially valuable in professional environments where multiple displays and sources must operate seamlessly.

Integrated IR and High Resolution Audio Support

The extender includes IR sensor support, allowing remote control signals to pass between source and display locations. It also supports advanced audio formats including Dolby TrueHD, Dolby Digital Plus, and Dolby Atmos. This ensures high-quality audio performance alongside 4K video transmission for home theater and commercial AV applications.
