So I have a 144hz Asus monitor I use for gaming, but I just recently noticed on my games settings that my refresh rate is locked at 60hz in fullscreen view, which it has never done before. I have v-sync off as well as framerate lock off, and I am pushing out 100 - 120 fps, but in the past my monitor would be able to be set to 120 or 144hz refresh rate to match what my fps would be getting. Is this because I switched from a Display Port cable to HDMI? That is the only thing that I can think of that I have changed since I first noticed this problem. Any advice/answers will be greatly appreciated. Thanks!
