[SOLVED] My monitor won't stop cutting in and out when set to 165hz

My graphic card drivers are all up to date and whenever I switch to 165hz from windows settings the monitor goes black then normal over and over and doesn't stop. It seems like the monitor or computer can't handle it but the monitor advertised that it could and I build my first ever PC so it may be my fault. But my PC has Ryzen 5 3600 and the GTX 1660 SUPER and runs very fast so it should be powerful enough. And I easily get over 200fps in Fortnite, so that should be easily powerful enough.

I am using the one shipped with it. Should I try to buy another and see if that helps? In the meantime, if that didn't work, what else might you suggest?
