RE: 7680x4320 detailed 8k resolution
"Windows 10 Pro OS build 19041.630" across the lot of computers.

diff of the W1650 and W1050 export files (csv & bin) from CRU are the same.
diff of the S1050 and W1650 export files (csv & bin) from CRU are the same.
I presume this is the PnP data passed to the computer from the TV, and saved in the Registry; CRU then allows for reading / editing of this data. If that is the case, then it is a mystery to me why the NVidia Control Panel does not offer the same options using the same 1050 card and Samsung TV.

I did a clean install of the latest nVidia drivers on W1650 (same work computer using the 1650 card), this time I used the DCH (Studio Drivers) for stability with a clean install, instead of the GRD (Game Ready Drivers). No success

DDU cleaned work computer and installed latest GRD on W1650. That took a while, but no success.

To add insult to injury, and to even further taunt me, my laptop with old 419.72 drivers and a nVidia 970M chip has no problems with the option and setting of the 7680x4320 resolution on the Samsung TV.

There also seems to be higher bandwidth options with the 4k settings on all the systems that can display 8k. The W1650 is missing expected options in the "PC" section of the nVidia Control Panel. From the nVidia Control Panel:
L970M @ 3840x2160 offers only 120Hz and 100Hz Refresh rates with only 4:2:0
L970M @ 4k x 2k (native) offers 60Hz down to 23Hz, with all 4 color formats
NOTE: 4:2:0 is only an option for 60Hz with 4k x 2k.
W1650 has the same "4k x 2k (native)" options as the L970M, but the "7680 x 4320" and the "3840 x 2160" options in the PC section are missing.

Other thoughts:
  • 1650 nVidia card should support G-Sync, according to online specs
  • nVidia 3060 cards (w/ hdmi 2.1?) are suspected to be released on Dec. 2nd for ~$450
  • I bought a Radeon RX 550 card to test
  • Samsung TV has a firmware update from 1402 to 1403, installed and removed SAM7040 with CRU to get updated PnP data if any. I can't find the details about what is in the update, but this may have been an update for G Sync.
