So I got a new monitor and for some reason my graphics card won't allow me to run on 75hz. I tried using this monitor with my laptop and it worked fine using hdmi and ran on 75hz. I tried it on my cousins computer which has a 750 ti and it ran on 75hz as well. I then connected my graphics card to my cousins computer and it then didn't work even with latest drivers. I tried using both hdmi ports with no success, leaving me to the conclusion that the problem is the graphics card. I wanted to ask whether this graphics card doesn't have support for 75hz and above or something?
