Question cannot run games higher than 60hz

[JoshGonePc]

Hello, I am having issues when playing games higher than 60hz which causes black screens and black screen flickering. I have a alienware 240hz compatible monitor so this shouldn’t be happening. I have tried 3 hdmi cables and everynow and then i get a message from my monitor saying to change audio format to pulse code modulation but when i go into settings I cannot find it
