I've had this problem for the past few weeks, where my ASUS TUF VG27BQ monitor on startup, after putting my PC to sleep, goes dark and flashes white for a split second at constant intervals of about 5 seconds and then after 10-15 minutes of doing so the screen goes white and starts to almost "render in" in real time all the pixels on the screen until it starts to function again, which has been frustrating to say the least. I have videos of the problem which I have "Streamable" links for below (valid for 2 days). I have also identified that the problem is not my graphics card or its wire, seems to be the monitor or the AC adapter block with its wires for the monitor DCIN input.
