Intel Arc A750 Black Screen

[genegx]

I have a new setup, ASUS ROG Strix B760-A Gaming WIFI motherboard, Intel I5-13400 CPU and an Intel ARC A750 video card.

Have had this system up and running for about a month. This week (first week of March 2023) I have had this problem two days in a row.

The first time was within an hour of turning on the computer. Suddenly the monitor went black, and displayed a no signal message.  I tried plugging in a different monitor, same thing, black screen, no signal. I switched from HDMI to Display Port cable, and tried in more than one port. No luck.

I shut the computer down and left for a while. When I came back I removed the A750 card, and plugged in the monitor to Display Port on computer back panel for the integrated graphics. Turned on, all was fine. Checked for any issues and saw none. Shutdown the PC and put the A750 card back in. Changed the monitor cable to the A750 card, booted the computer and it worked fine, was OK rest of day.

Second time, computer had been on most of the day, and in the early evening same thing happened, monitor went to a black screen. No noticeable glitches or anything, just suddenly the screen goes totally black. Tried swapping the monitor cable to the back panel input for the integrated graphics. Nothing. Shutdown the computer, and a few minutes later booted again and it came on fine with the integrated graphics. Shutdown for the day.

Again started up fine with the integrated graphics.  I just now switched the DP cable back to the A750 with no problems.

Event viewer shows no hardware event for these times. So no clue whats going on. ARC drivers updated to latest January release. I frequently use the overlay when gaming to check usage, temps, etc, and all look fine.

Anyone have any ideas what could be going on here?

Thia has not happened again. I think it may have been fixed by the update you released around that time. I also had a problem with the screen not waking up after the monitor went to sleep. I'm not sure if that is fixed, as I just set my PC to never sleep the display(s).

I very much appreciate your quick responses to these issues.
