now I am getting 2160p with Netflix AND Dolby Atmos is now working on both Netflix and UHD discs.
and re Claw's suggestion of 4.4.4, somehow every time I choose that setting, the screen went blank for a long while and it reverts back to 4.2.0??!
it has never allowed me to do 4.4.4 from day one.
once i fix this I am happy!
is there something I need to do with the Denon 6500H or JVC RS2000/N7??? I would think my equipment is 4.4.4 capable?

We don't know if your cables are 4:4:4 capable. 4:4:4 requires much more bandwidth, so is much more taxing on cables. Both cables in the chain should be premium certified. Any cable longer than 25' will probably need to be fibre.
When you switch to 4:4:4 the player sends a test screen to your display asking if you see the 4:4:4 image. It gives you a certain amount of time to reply yes with the remote. If it doesn't receive this confirmation, it reverts back to 4:2:0.
This is almost always caused by an insufficient HDMI cable. However, with the JVC projectors, it might be another problem: The JVCs can take so long to re-sync from 4:2:0 to 4:4:4 that the test image times out; so you never see it, never confirm yes, and the player goes back to 4:2:0.
If you have another 4K display, you can test this using the same cables. If it doesn't work, you need a better cable or cables. If it works, leave the Panny set that way, then reconnect to the JVC. You should be getting 4:4:4 then.
Denon only supports up to 4K60 4:2:0 8-bit when the 4K Signal Format
option is set to its default value Standard
. Make sure it is set to Enhanced
In the UB820...
4K60p Output must be set to 4:4:4.
Advanced...Color Mode must be set to Auto
Before attempting to change the 4K60 Output setting put your JVC into an SDR picture mode; one that does not use the BT2020 Color Profile. This will reduce the HDMI sync time since the JVC doesn't have to turn OFF the filter when it gets the SDR signal.
Also try a couple of times if the UB820 times out while waiting for an OK. On the second attempt I usually get around 3-4 seconds to click the OK button when it appears.
If you don't ever see the 4:4:4 confirmation screen before it reverts to 4:2:0, it is possible your HDMI cables don't support 18Gbps signals.
If you have the 4K60 Billy Lynn Halftime UHD disc and it plays for you then your HDMI cable is good. If you get 4K HDR from Amazon Prime Video the cable should be good. Because I know that my cable is good, I will sometimes not wait for the 4:4:4 OK screen to display and just click the UP and OK buttons after a few seconds.
