When I connect my 3080ti to qn90b via HDMI 2.1, my 3080ti to soundbar via passive displayport to HDMI adapter and my qn90b to soundbar via HDMI ARC, the screen is blank till it reaches the windows login screen with no motherboard POST so I cannot get to the bios. When I disconnect HDMI ARC between qn90b and soundbar and boot my system, the motherboard POST shows and I can get to the bios.
When I plug my 3080ti to qn90b via active displayport to HDMI adapter (supports DSC), my 3080ti to soundbar using a passive displayport to HDMI adapter and my qn90b soundbar via HDMI ARC, the screen is not blank and I am able to see the motherboard POST screen and I can get to the bios here.
I would prefer to use the first method since I can get VRR. I cannot for the life of me figure out why I cannot get the POST when I boot up my system with the HDMI, passive displayport and HDMI ARC all connected.
I cave updated the 3080ti firmware to update the displayID but that does not affect HDMI does it?
