[RTX 3080 TI SUPRIM X] MSI users with issues with displayport connection to a monitor - black, artifacts boot

[baneslayerr]

Hello,

Any 3080 ti user with errors connecting to a monitor?
Error meaning:
> Black screen until windows
> No capability to enter bios
> Black screen with artifacts until windows pops up

As reported in this thread https://forums.evga.com/RTX-3080-TI-FTW-ULTRA-Cant-see-BIOS-post-screen-w-DP-port-m3410892-p3.aspx, the issue happens with CSM disabled (essential to have reSize Bar) and a displayport connection.

My setup:
CSM disabled, reSize enabled
ASUS XG258q (HDMI 1.4, HDMI 2.0, Displayport 1.2

Results:
HDMI 1.4 120hz - works flawless without errors during boot, BIOS accessible
HDMI 2.0 240hz - works flawless without errors during boot, BIOS accessible
DISPLAYPORT 1.2 240hz - fails (black screen with artifacts) until windows loads and then everything is perfect

Nvidia provided multiple fixes to monitors (1.2 DP and 14 D.P) and that solved some of the issues.

and also

Also, brands like EVGA and ASUS created specific vBIOS versions to avoid this issue.
None of these helped my case.

This happens with old and new monitors. Example from the EVGA thread above:
"Same problem. RTX 3080 TI FTW3 Ultra with an MSI MPG X570 Gaming Edge Wifi mobo (both latest BIOS) and Samsung G9 Odyssey 49" ultrawide.
Some observations:
Monitor at 240Hz, Displayport 1.4, no boot.
Monitor at 120Hz, Displayport 1.4, boots, no UEFI splash screen. Screen comes on when Windows has booted.
Monitor at 60Hz, Displayport 1.2, boots with UEFI splash screen.
If I enable CSM, PC will boot at 240Hz but that causes other issues (such as resizable bar turning off). I almost RMA'd my GPU because of this. "

Just want to understand the experience of the users here, specifically MSI SUPRIM X users. DO you have the standard bios? the default one?
Have you got any update from MSI center or support?

Thanks in advance.

My vBios:
94.02.71.40.15 - GAMING mode
94.02.71.40.13 - SILENT mode
(aka the "Default" ones)
