A CDE Definition
See 4K pass-through.
A feature of an A/V receiver that allows a video source to pass unaffected through the receiver to a 4K TV without any processing. For example, all 4K content from a 4K source or an upscaling 4K Blu-ray player must be passed directly to the 4K TV.
In order to transfer a 4K signal at 60 fps, receivers must be HDMI 2.0 compliant (see HDMI versions). Some receivers also include 3D pass-through for 3D content and 3D TVs. See 4K upscaling and 4K TV.
