AW3225QF, stuck on Pixel Refresh?

Yesterday, I made a post mentioning that my AW3225QF monitor had started going black intermittently. This prompted me to investigate the behavior more closely.

The monitor functions normally for a few seconds, then the screen goes completely dark—so dark that not even the OSD appears when pressing the joystick. However, the monitor remains powered on, as the LEDs stay lit, and Windows still recognizes it as an active display. I can even move windows to the monitor (though obviously, I can’t see anything since the screen is black).

The only way to get a few seconds of use is to turn the monitor off and then back on. It works fine for about 10 seconds, then the screen goes black again—almost as if a Pixel or Panel Refresh had been triggered.

What led me to this conclusion is that, during one of those brief usable moments, I manually triggered the Panel Refresh. The screen went black, and after the process finished, it displayed the usual color calibration lines. Then the monitor shut off, requiring me to turn it back on manually. After doing so, the same behavior repeated: it worked briefly, then went black again after about 10 seconds. This behavior led me to believe that the monitor is looping some sort of "Pixel refresh" and that's why is putting my display completely black.

I hope this information is helpful to anyone experiencing the same issue.
