Question Pioneer vsx 923 4K pass through

[Shiftynagasaki]

hi there , I’ve had this amp for a few years and just recently upgraded my player to a 4K one, however when I connect through the amp it only displays in 1080p
I’ve gone back to the pioneer site as well as looked back at reviews and they all state that this unit has 4K pass through? Some search results have stated that it can’t actually pass through 4K surely all the reviews and pioneers own site can’t be wrong
Anyone have any ideas or can clarify
Thanks

The receiver predates HDMI version 2.0 so it will not include HDCP 2.2 compliance and its 4K passthrough capabilities will be in association with frame rates below 30Hz. Passing through 4K video will only be possible if the source isn't protected by HDCP 2.2 copyright protection and if it has a frame rate below 30Hz. Almost all commercial UHD content is protected by at least HDCP 2.2.

Its 4K passthrough abilities are for all intense purposes useless without the inclusion of HDCP 2.2 compliance.

OK I see, thanks for the explanation
