Good day team!
Noticed after watching a movie that was HDR seemed very dark and also had the same movie with no HDR and was quite different (brighter)
Same movie, similar file size (~30gb) one is HDR one is not. Both appear to be 10bit.
HDR file is very grey and flat, non-hdr file much more colorful and bright.,
I have a Sony XBR75X900E & Denon AVR-X2300W
Adjust Refresh rate is set to Always, and gui is at 1080p
I know in the last year there were a lot of improvements done with this on the Vero 4k, so if there are issues like this, are we thinking it might be due to poor encoding?
I have a bunch of comparison info i did on both files, as well as my equipment which is 4K and HDR compliant and new 2.0 hdmi cables.
