People that have a 4K player can still play 4K/UHD on their non-4K display and receiver. (1 Viewer)

You are multiple revisions of the HDMI standard behind and it’s definitely time to upgrade those cables when upgrading equipment.

Now, until you upgrade your AVR to one that’s 4K capable, it won’t matter as much. But those older cables will limit a 4K player’s output to HD only. But then again, so will your receiver.

Hey Josh (or anyone else who might know), Regarding this comment, I have a 4k player (cheap LG 4k player) connected via HDMI to my Yamaha amp (RXV 1083 which does 4k passthrough) which is then connected to my 1080p Projector (Benq W1070). I am using an older HDMI cable from the amplifier to projector and just bought a new HDMI cable that is 4K compatible for a future projector purchase (I am sloooowly working to 4k) but I haven't installed it yet because I fugured there was no difference - digital being digital.

Are you saying there is actually a difference and that upgrading the cable to the projector would actually improve the picture quality I am currently getting from the 4K down conversion? Currently, my player or amp is doing some sort of down conversion from 4k to 1080p. I am not entirely sure where that down conversion occurs actually.

What about sound quality? I am thinking the sound is coming from the feed from the 4k LG to the Yamaha amp and is not being down converted (so I am getting true Dolby Atmos sound from the 4k disk) but maybe I am incorrect. If the 4k player sees a 1080P "marker" (for lack of a more technical explanation) or limiter, does it then downconvert the entire signal, audio and video, before it even gets to the amplifier?

Sorry this is a bit of a book... I am sure I am not the only person confused by how all the signal processing works in this situation.

Thanks for any insight,

Kip

Check the player's settings. My LG BR player will do this but it can be turned off in the device settings menus.

I have the LG player set to "Off" to stop auto shut down but it makes no difference to some 4K discs which after I pause playing for a few minutes, go back to the beginning of the disc. It's only some labels/studios affected such as Paramount and Universal. Doesn't affect 4K discs from Warner Bros, Kino and others, which resume from pause or stop..

There should be no A/V quality diff.

Dolby Vision will not allow 4k discs to display on a 1080p screen at 24hz

it will force the output to 1080p60hz

annoying but that’s dolby

I bought my first 4K UHD discs and a Panasonic 820 player in 2019. In 2024, I finally replaced my Samsung plasma with a 77" Oled and then I had about 350 4K UHD releases.

OK, thanks for the input. HDMI 2.0 vs 3.0 or whatever it is doesn't effect quality of signal then. Good to know.
