Hey! I've noticed some issues lately that I'm struggling to fix. Over the past few weeks, two of my monitors connected through DisplayPort have started flashing all black and then back to normal in sync. This only happens when you move your mouse; it doesn't occur when the mouse stays still. The third monitor, which uses an HDMI to DVI adapter, is working fine. Key details: the black flashes are triggered by mouse movement, not by any software or settings. I've tried updating my BIOS, refreshing the firmware on the main display, switching from Windows 10 to 11, power cycling everything, and even leaving it unplugged overnight. Powering it back up resolved the issue temporarily. It seems more frequent when the PC wakes from sleep. So far, I'm at a loss for a permanent solution. Any advice would be greatly appreciated!

PC specs: Windows 11 Education Version 24H2 64-bit
Motherboard: ASUS TUG Gaming X570-PLUS (Wifi)
Bios version: 5021
CPU: Ryzen 7 5800X3D
RAM: 4x Corsair Vengeance LPX DDR4 3600MT/S (8GB total)
GPU: ASUS TUF RTX 3070ti
PSU: SeaSonic Focus GX-1000 (1000W)
Monitors:
1. Samsung Odyssey G7 32-inch (DisplayPort cable) – affected
2. Acer GF276 (DisplayPort cable) – affected
3. Dell 1708FP-BLK (HDMI to DVI-D adapter) – unaffected
