I hate doing this stuff i want to get it right from the get go.. I know if i mess something up ill be stuck all weekend trying to figure it out..
once i get this going then ill come back and ask what else i need to check off on the vertex to convert my uhd hdr10 disc with my oppo to DV..
Make sure you connect the TX0 HDMI output connector from the Diva to the RS640. the TX1 output is 1080P only.
On the Diva EDID tab of its UI, you can either...
- Select the CUSTOM radio button and choose EDID 5 (Sony A1 LLDV) or EDID 8 (LG65C8 LLDV). I would suggest trying with EDID 5 first.
- Or select the AUTOMIX radio button and...
Mark the FULL Audio Flag check box
Mark the DV FORCE LLDV check box
Clear all of the other AUTOMIX check boxes. None of them are needed and may cause issues if enabled. The only other check box you might have use for is if you have an HLG source such as Directv 4K as I believe the RS640 supports HLG input.
CUSTOM and AUTOMIX are independent of each other. It is an either or choice. Options set under CUSTOM don't affect AUTOMIX, and options set under AUTOMIX don't affect CUSTOM.
I can see no difference between Automix/Force LLDV, Custom EDID 5, and Custom EDID 8. I thought I did at one time but I think it was either the content or my bloodshot eyes. I am pretty sure that HDfury uses the same Dolby Vision identification string for all three cases, and based them all on the Sony LLDV EDID 5.
As long as your Oppo is also connected to your AVR, you don't have to change anything else in the Diva (not sure why you still want to use the Vertex?) to get LLDV from Oppo disc playback. The same Diva LLDV settings work for both ATV4K and Oppo.
In the Oppo, go to Setup...Video Output Setup...HDR Setting...
For HDR option, choose Dolby Vision
For Dolby Vision Processing option, choose Player-led
That's all. I can almost guarantee you will be much more pleased with the ATV4K LLDV result on your JVC than you will with the Oppo LLDV output.
Do note that the ATV4K can be very finicky about its Dolby Vision setting. If you make any changes in your AVR or Diva that affects the EDID information that the ATV4K receives, the ATV will make you test Dolby Vision capability all over again before it will let you set it to Dolby Vision.
I leave my ATV4K at
4K60 Dolby Vision
Match Frame Rate ON as most of the content is 23Hz and can result in judder if output at 59Hz.
Match Dynamic Range OFF to convert everything to Dolby Vision.
But I will set Match Dynamic Range to ON if I don't like what some SDR content looks like when converted to Dolby Vision.
Since almost all HDR content on the ATV4K is encoded in Dolby Vision you don't have to be concerned about it having to convert HDR10 to Dolby Vision and output as LLDV. I think this is one reason I like the LLDV from the ATV better. It doesn't have to do any conversion from HDR10, just output the Dolby Vision content as LLDV which is what it was designed to do automatically when connected to Sony Dolby Vision TVs.
