Problems encountered when Mac connects to Samsung G80SD Monitor

[Rabbit_Spec]

My MacBook Pro with the M4 Max Chip connected to the G80SD via DP experiences sudden screen flickering after waking up the computer.

And after the Mac goes to sleep, the G80SD frequently wakes up on its own, prompting that DP is not connected.

After I used HDMI to connect the Mac, all issues were resolved.

My Mac's system firmware is macOS 15.3.1, and the firmware for G80SD is 1313.2.

Does anyone have any good solutions? I can confirm it's not a cable issue; this cable works perfectly with the 32GS95UE and AW3225QF. Of course, I also tried using the DP cable that comes with the G80SD, but it's still the same.

Hello! I would also recommend test the monitor with another PC if possible, this is to see if there is a specific issue with the monitor if it's a compatibility issue with the Mac. As you said that it was resolved using the HDMI cable, there could be some with the display port on the monitor. You can also try a factory reset on the monitor to resolve this issue also. As the only other step after this would be service. Depending on your warranty, you will have a few options for service. 

- If your device was recently purchased, you can check with your retailer on their return/exchange processes.
