Help me get RGB color PC > Dr HDMI 4k > Sony Z9D

When it is in 4k60 YCbCr420 is it 8 or 10-Bit in the nvdia panel?  ... as if you try to force nvidia on HDMI2.0a to 10bit 4K60 it will push you from RGB to 4:2:0. 

It may also be something about Windows trying to use the onboard intel graphics, not finding the attached display and defaulting.  Try turning off the iGPU in the BIOS for testing.

8 bit. Control panel won't allow anything but YCbCr color.

Hmm windows finds the correct gpu when Dr HDMI is set to 4k60-420-8b-300M-HDR-BT2020-3D-FULLAUDIO, but I can try disabling on board gpu for testing.

So hot plugging "fixs" it, but is that hot plugging the Dr HDMI into the HTPC or the cable that goes into the DR HDMI from the Denon or something else.  If the Dr HDMI is "working correctly" you should be able to plug in/out anything after the DR HDMI without Windows noticing a thing.  If Windows does notice something, then the DR HDMI is not doing it's job.  If it is between the HTPC and the Dr HDMI then it is doing it's job, but for some reason windows is not seeing the EDID info after a reboot (did you try a cold boot?). 

tzr916:
Hotplug just means, all the physical connections are in place (PC > Dr HDMI >  Tv only or Tv+AVR only) while pressing buttons on Dr HDMI to change between EDID tables. So, if I press buttons to change from the current working EDID table to one that HDFuryhelp says should work, I see the picture on the tv flicker/black out then come back On. The desktop may come back as 4k, or it may come back 1024x786. If it does pop up as 4k, when I reboot the PC, it reverts to 1024x768.

Yes, cold booted (leave Tv+AVR On):
-PC On using the current working EDID table
-power PC OFF
-disconnect Dr HDMI (input and output)
-disconnect other monitors
-change Dr HDMI from working EDID table to one that HDFuryhelp says should work
-reconnect Dr HDMI
-do not connect other monitors
-power PC On
-boots up and is 1024x768

And I have Factory Reset the Dr HDMI 4k twice, connected it via USB to my laptop to verify current firmware, view and upload a few different MonInfo EDID tables, etc.

jmone:
I'm out of ideas.  You may want to test the Dr HDMI with the laptop as the source to see if it is faulty.
