Screen comes on at windows login

[dsl10007]

Hi

I have an Intel ARC 770 card, connected to a Samsung 49" CRG screen

When i boot the computer i get no video signal at first, very seldom do i see the BIOS screen.

Usually i have to wait until the computer booted all the way to the login screen, then it will show the login screen and the computer will work normally.

This is using HDMI, if i use DP, i will usually have to reset the computer multiple times before it will even get to the login screen.

Is this a known problem or not. I just updated to the latest drivers, and it seemingly also flashed the card BIOS, this made no diference.

Have had this problem for a while, at first i thought the computer would not boot at all, but that was because it stopped at the Bitlocker screen but did not turn on the video signal, i disabled bitlocker for other reasons and found out that on HDMI it will boot fine every time, but 9/10 times it only shows video when getting to the login screen of windows 11.

Hello dsl10007

Thank you for posting on the Intel® ARC™ Graphics Communities.

I would like to get a log file from the Intel® System Support Utility so we can get you hardware configurations and driver details and make sure everything is ok. also, if possible share a short video showing this problem so we can get a better understating of what is going on.

In addition, please make sure that CSM compatibility module is disabled on your system, this is known to sometimes cause boot issues when is enabled in the BIOS.
