The second screen displays black and then ceases to function.
My second screen experiences a brief blackout followed by normal operation, sometimes resolving quickly when I power it off and on. Occasionally it occurs every ten minutes or an hour. It wasn’t a problem until this evening at 7 PM. My PC has been with me since January 25th, and today was the first time it happened. (File: 20240226_000330.mp4)
Check if the backlight shuts down or remains active when the screen is black. Reverse the connections between the monitors and observe whether the issue shifts to the other display or continues on this one.
it's likely the cable or GPU socket is the issue. switch to a different socket on the GPU and test again; if it works, replace the cable.
