I just bought a DP to HDMI adapter from best buy and I got home plugged my HDMI cable to the adapter and my end of the graphics card, plugged the displayport into my monitor. At first I was getting no signal at all from anything. So I connected my Blue weird cable to my monitor and my pc. After that I got stuck in unknown resolution cause my display settings don't show anything, all of the boxes are greyed out. When I go to my amd control center it says it is in 1080p running 120hz. But it is clearly not. Ive tried re-plugging cables and messing around with the settings but I'm stuck in this resolution and my adapter doesn't work, All I wanted was 144hz because my graphics card does not have a display port. How Do I go back to 1080p with 144hz?
