Did you connect 8+4 Pin Connector TOP Left of motherboard. I have a CH8, 3900x / 2080ti and functions on all the bios since launch (not that this helps, just saying it isn't nvidia thing, so don't need amd card to test with).

Whoops, I misspoke, sorry...yes, 1302 was the BIOS I flashed to on my final attempt.
Power connections are CPU 8-pin (didn't connect the extra 4-pin, thought it was optional), 24-pin, and 2X 8-pin for GPU.
I'm using a brand-new and good quality DP cable from Kabeldirekt. Monitor wakes, then goes back to sleep.
I'm stumped LOL.

the problem is not the DP cable.
I think, because CSM settings are disabled and this legacy only. You have to change it to enable, and make sure legacy and Uefi.

csm is not the problem .... mine is off and works fine ..... it has something to do with signaling between the card and monitor
I can trace this back now to a firmware update that Corsair iCUE did on the cooler that caused this problem and that cooler has issues on any board it's put on now

Brand-new build, doing pre-testing on my table before assembly. Same trouble, C8H fails to complete POST and hangs at Q-code 02 with a green LED.

Tried both new 2070 for this build, and a good 780 from my previous machine. I don't have an AMD card to test with. Many other troubleshooting possibilities tried. Head scratcher.
