I've read much online about the RTX 40xx series graphic cards not displaying the BIOS screen during startup.
I'm having a similar problem that I can't seem to solve.
So far I've updated the ASUS Mobo Bios, Updated the Intel ME, Installed all of the latest Nvidia Graphics Drivers,
and performed the Nvidia "FIX" that supposedly solves the blank display problem during startup.
However, none of the above solved the blank screen issue during bootup on my 4K monitor using display port or HDMI.
The BIOS will display on an HD monitor using display port just fine.
I can't think of much more to do regarding this issue and was looking for additional suggestions from the community.
Thanks in advance for any input !
