Post screen skipping on startup

[Air_iq_]

I've had an interesting problem I think that revolves around Displayport with my 1080 Ti. When I start up my PC the post screen allowing you to get into the BIOS is skipped it's a black screen and it just goes into Windows not that it matters. However it's just with my 1080 Ti that this happens my Vega 56 that I've tested does not have this issue so I can get into it on the monitor. I've reset the CMOS and BIOS multiple times and updating the actual motherboard BIOS and even going to a previous one I'm still encountering this issue unless there could be something with my card's VBIOS.This doesn't happen over HDMI however so I'm uncertain of that and am wondering what it might be given I've used this card on several systems and not encountered this issue unless it's a long term use issue. It's quite a niche and nitpicky problem to be having especially since I'm planning on upgrading my GPU down the line but I do like having easy access to my BIOS on startup that's not thrilling.

this has to do with a combination of how long the card's bootup sequence takes to get to checking each output and the sequence the motherboard checks PCIe connectors. Your card probably starts with HDMI and then DP1, 2 etc. which is why the post screen is done before your display output is active. your bios should have a "quickboot" or "rapidboot" fastboot etc kind of setting which skips a few steps of the post to speed up booting. it usually skips things like checking every USB device, sata header, ethernet connector etc and uses windows to detect things like usb drives instead of the bios. 

 

if you mash the del key when you power up you can still get into the bios settings, it just wont display the post screen until the graphics card has finished it's internal checks.
