3080TI FE on Maximus XI Extreme will not turn monitor on until Windows Log-in Screen

[Jesseinsf]

I had a similar problem. Computer will boot with DisplayPort, but not with HDMI. Tried DP to HDMI cable but still didn't work. Just now, got working with CSM enabled and everything manually set to UEFI as documented here:

https://hardforum.com/threads/pc-won...to-tv.2019052/

I have an Asus CH7 Dark Hero with BIOS 3904 (as 4201 was having both strange issues with ARGB and Clonezilla with drive identification; rolled back and was fine), and Strix 3080 OC 12GB.

Hope this continues to work...

Resizable BAR doesn't work when CSM is enabled (regardless if UEFI is chosen when CSM is enabled). Also, Windows 11 doesn't like CSM mode being enabled (regardless if UEFI is chosen when CSM is enabled).

Also, my issue is different. My PC boots, it's just my monitor will only turn on at the Windows account sign in page (which prevents me from accessing the system firmware/BIOS). This only happens during a system restart when using DP and is a toss of a coin when using HDMI. If I shut down my PC completely and then turn it back on, then all works great when using DP (HDMI will work intermittently when powering up from a complete shutdown).

Have you found a solution?
I am also with the same issue.
ASUS XG258q monitor with SUPRIM X 3080 ti.
Only difference is that HDMI works without any issue.

Displayport : screen starts and then only when it reaches windows sign in, it appears.

CSM change doesnt matter since resize bar will be disabled besides the win11 thing you were saying.

Not sure what to do.
People say flash my msi card with an asus or evga vbios that has a fix or even change the monitor.
I am not really looking to do that.

Someone else suggested a fake hdmi plug and put it on the card to "trick" it to think it's going with hdmi.

HDMI is the only way for me to reach bios.

Any options or alternatives?

I have not as Arrogant Nvidia thinks that nothing is their problem. To them, the problem is some other companies' problem. I made up an illness for this: Corporate/Fanboy Clinical Narcissism.

I had similar problem.
EVGA 3090Ti (recently purchase)
LG 27GP950.
I did not have problem with my LG monitor when it was paired with 2080 Ti. As soon as i install EVGA 3090Ti, i cant see boot screen at all until windows.
mine was fix with Nvidia Vbio Display ID bios fix.

That VBIOS fix was only for LG monitors.
