I have the Panasonic UB9000 $K player, attached to my JVC 9000 projector. The projector was tuned by a JVC expert and he was the one who recommend this player. I made my intimal settings and got a dramatically good picture.
Someone suggested that I watch a YOUTUBE video featuring the proper settings for the Panasonic 9000 and 820 and I did. I had two of the five or six settings aligned, but learned about several more and so I changed them
The results were spectacular. I went to what I thought was great to something greater. Better color reproduction and better detail. And better black and white.
So If you have a chance watch this video.
