What are 4K pass-through and 4K upscaling?

    The 4K pass-through feature is High-bandwidth Digital Content Protection (HDCP) 2.2-compatible and allows data to pass through the system without quality loss. The AV receiver with the 4K pass-through feature sends 4K signals from video devices to a 4K TV or 4K projector while maintaining the 4K resolution.


    The 4K upscaling feature allows low-resolution data to be upscaled to high-resolution 4K signals. An AV receiver with the 4K upscaling feature lets you enjoy video signals input via HDMI® connection as smoother video with depth.



    • HDCP 2.2 is a content protection standard required to play copyright-protected 4K content.
    • To enjoy the 4K pass-through and 4K upscaling features, a High Speed HDMI cable is needed for the connection.
