Recently I bought a Dune HD base 3D media player. I connected it to my Denon 3808 through HDMI and image quality was good, but not as good as my Denon dbt 3313.
I have found that Dune has deep color settings. Mine was 8 bit default, so I changed it to 10 bit and the image improved a lot. Then I tried 12 bit but Denon 3808 seems not to accept this setting. The image appears and disappears constantly. Reading the manual, somewhere is said that Denon 3808 supports 12 bit deep color. Connecting Dune direct to the TV I can use 12 bit deep color without any issues. Anyone knows how to solve this? Thanks.
