Definition of: 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.
Is 4k pass through necessary?
High-speed HDMI cables can carry 4K signals. The connection in your TV or receiver is what needs a specific HDMI version, and for 4K to work you need HDMI 2.0 or 2.0a. If you’ve bought your TV and other gear within the last 2 years, you’re probably all set (and your cables will almost certainly work).
Do you need a 4k receiver to watch 4k TV?
The TV, and all your gear, will work fine presuming you don’t have a 4K source device. You can do this with an optical digital audio connection, which nearly all 4K TVs have. Or, if your TV and receiver are Audio Return Channel-compatible, you can use the same HDMI cable used for the “monitor” connection.
What’s the difference between 4k and 4k upscaling?
4K upscaling is the process where the player enhances the original input resolution. 4K native content means that the input resolution is already 3840×2160 (4K). Although both native and upscaled offer the same resolution, native 4K is better as the picture contains more detail. Using upscaling detail cannot be added.
What is HDMI pass through on a receiver?
The HDMI Pass through feature lets you output the HDMI® signal (audio/video) from a Blu-ray Disc®, cable box, satellite receiver or other source device to the TV even when the receiver is in standby mode. All of the devices used must be connected using an HDMI connection for this feature to work.
