Intel Arc Displayport problem

[FanHi]

Hi,

I'm having a few different problems with my Intel Arc A770 LE, but today I got a new one which I would like to report / get your help with.

I have been using the 4499 beta driver since it got released and experienced the usual (I'll add a summary below) problems.

Today the card crashed, as it randomly does ever other day, but after I restarted the PC, the display stayed black.

I have been using this exact display with this exact cable since I got my card, half a year ago.

It is a Samsung C27HG70 with the latest firmware and I had connected it with a Displayport-cable.

After todays crash, the monitor won't work with the exact cable that had been working all this time. A different monitor, with the same cable, works just fine. The Samsung monitor also does work when plugged in with HDMI - but now the really weird thing: the ArcControl software shows the display as beeing connected via Displayport. (see screenshot)
In the meantime, I have updated the Intel Arc driver to the latest stable 4502 (ddu before that). The mainboard (B550 AORUS ELITE V2) has the latest bios and above 4G decoding and ReBAR are enabled.
The OS is Windows 11 and all updates are installed.

Now for sake of completeness, a summary of the issues I've had over the last weeks:

The screen shows visual artifacts (random colored blocks and streaks or partially black or flickering screen) after some time. I can't reproduce the issue consistently, but I have a feeling, it happens when using 3D-games or apps at the same time with certain websites that use animations or have videos embedded. The issue persists for a few minutes and then the card crashes to a black screen after which the system has to be restarted.
Sometimes Win+Ctrl+Shift+B improves it a bit, sometimes it doesnt.

The bug where the Windows screen capture tools won't work anymore. I've noticed this issue for months now, and can't reproduce it reliably. I've read in other threads, that the issue seems to have to do something with the systems uptime and will only appear after several days - but since I'm having another problem with my PC (might or might not be related to the gpu - i did not have this problem with my old nvidia card, however), where the PC consistently wakes from sleep after one minute, I restart my PC several times per day and I still experience this bug.

The screen randomly turns black and the PC has to be reset.

Sometimes, games and apps report "no compatible video card detected".

Idle power consumption is 40W when using 144Hz. Drops to 11W when using 120Hz or below.  (Workaround applied)

Sry for this wall of text! Hopefully someone has suggestions on how to fix these problems or can tell me if this is likely a software problem that will be fixed soon or if the card itself is faulty.

Also, if any of the intel engineers that work on these problems, need any additional informations for debugging and fixing the problems - i will gladly try to help!

Thank you!
