Hey guys. Im trying to overclok my Philips PHL 273V7 to 75Hz. My drivers are patched but when i set refresh rate more than 68Hz, monitor goes black and says: "Cannot display this video mode. Use 1920x1080@60Hz". Somehow i managed to get 75Hz working, but after rebooting PC it has gone and now i have only 68. What did i do wrong?
