How does down resolution work? (1 Viewer)

[Dave>h]

Hi,

I recently purchased Heavy Metal 4k UHD.

I have an LG 4k player connected to a Yamaha RXV 1083 which is further connnected via HDMI to a Benq W1070 1080p projector. Additionally, I have an xbox one connected via HDMI to the same Yamaha amplifier going to the same projector.

In doing a side by side comparison, I noticed the while the sound seemed to be a significant upgrade from the Bluray (Atmos vs 5.1), the picture quality on the downres ed 4K disk vs the blu ray was underwhelming. In fact, the bluray looked quite a bit better.

Why would that be? Does anyone know? Where in the signal path does the down resolution occur? Within the LG or at the Yamaha level?

Just feeding my personal curiousity and any help is greatly appreciated.

Regards,

Kip

Without having anything else configured to do it, it's probably being done by the player, since it would automatically sense an HD display. The better the player, the better job it will do. The bigger issue is how it's handling HDR.

There are actually several variables at play.

Stephen,

Thanks for that. I figure there are actually quite a few variables at play. I am just curious why the downresed 4k would look worse than the standard 1080p. What would do that and why would it be that way? I would have thought, at the very least it would be on par with the Blu Ray picture although I kind of figured somehow it would be better, what with more data to work with. Seems kind of strange that it looks worse. And it is not just Heavy Metal, Aliens and True Lies also looked worse.

Thanks for the info but I guess I need to keep searching!
