Just finished upgrading my 9700k platform to 13600k / z790 Aorus Elite AX / DDR5.
Initially, on default BIOS settings and 2 monitors (Samsung G9 49" / 17" pos for discord) connected to 3080 ti, I got no video output whatsoever.
I later found that if I connected ONLY the old VGA monitor to the integrated graphics on the mobo, I was able to see BIOS and windows load normally. Further, once windows had loaded I could also hot swap the old VGA monitor from the motherboard IGP output over to the GPU and all was well.
In the case where I plugged one monitor to mobo and one to GPU I also got no video output to either monitor at boot. For some reason having the G9 and VGA monitor both connected to GPU at boot causes no signal on either monitor.
Since messing around a bit I have noticed that if setting IGP in BIOS to OFF, I receive no signal period from my GPU no matter which monitor or both is plugged in to GPU.
Setting the IGP setting in BIOS to AUTO, I have discovered a workaround. Once set to AUTO, if I plug ONLY the old VGA monitor to the GPU and let windows boot to desktop, I can then connect my G9 monitor to GPU and all is well. Everything is working perfectly until next boot. At that time I must unplug the G9 before boot or I will have no signal on either monitor.
There are no issues flagged in device manager, I have the latest GPU driver installed, and I have reset the CMOS several times (only setting I am changing after reset CMOS is to ensure that integrated graphics is set to AUTO) I have not yet updated the mobo bios. Previously, I have had 0 issues with the EVGA FTW3 3080ti.
Such a frustrating problem and at this point I am pretty much above my pay grade. Any ideas or suggestions would be very helpful.
