AW2723DF, random black screen with gsync on

[sew333]

Hi. I plugged this pc and formatted disk in uefi.
13900K stock
2x16 GB DDR5 GSKILL 6800
Rtx 4090 Gigabyte Gaming
Aorus Elite Z790 AX
SSD KINGSTON 2TB
Seasonic 1300W PX ATX 3.0 PCIE 5.

My monitor is Alienware AW2723DF 1440P


I have a G-Sync compatible monitor, and if G-Sync is enabled my monitor will go black for about a second if I open a store page in STEAM and scroll the video out of view. It will then go black again if I scroll it into view. The video plays fine and otherwise Steam itself works normally, but if the video enters or exits the visible area of the screen the display loses sync for a short while 1 second. It doesn't do it if G-Sync is off. No other application on my system causes this.

Go to Steam settings -> turn off hardware acceleration -> try again.

Maybe this resolves the issue.
