After using sensors-detect for the first time, screen's vertical rate turned to 1023 from 800. The original resolution of screen is 1280x800@60Hzt but now it is 1280x1023 and I can not change it whatever I did. I tried xrandr to revert it to original but if I choose a different rate other than 1280x1023, resolution looks horrible. It looks like its EDID was also changed. Could you help me to solve this issue?
