i bought the Club 3D CAC-1010 Adapter DisplayPort > DVI-D in December. It worked great and i finally could use the benq xl2411z again and turn to 144 hz . But today it just shows 60 hz in the nvidia control panel. Not even 120 hz. I dont know what happend. I had no problems with the cable yet. Is it broken? or am i doing something wrong? I didnt change anything i even went back to older nvidia drivers but it wont change anything in the Herz menu.
