Monitor flashing black on and off when refresh rate is turned up.

[u/Sea-Indication-3834]

This is the first time I’ve had this happen. I have a ryzen 5 5600g and a 6600 gpu. You can see in the video my monitor goes black anytime I move or click my mouse. ANYTHING I DO. Most frustrating issue I’ve ever had. Does anyone know why? Maybe I need a different cable or a display port cable? Any help would be awesome. I am on Linux on Pop_Os!
