Describe your problem. List any error messages and symptoms. Be descriptive.

AOC Monitor has random black screen flashing when using Freesync on 75Hz.

List anything you've done in attempt to diagnose or fix the problem.

Changing my refresh rate to 60Hz fixes the problem but I want to use 75Hz. I've tried upgrading and downgrading drivers for the AOC monitor and my GPU and have tried different DisplayPort cables but still get the same problem.

Could my monitor or GPU be defective? I've tried looking all over for people with similar problems and have tried every solution I could find to no avail. Am I drawing too much power from my power supply? Would having my other 2 monitors at 60Hz be why? I didn't think Freesync and this monitor would be such a hassle!

Thank you for any feedback! :)
