Hey everybody! I have a problem with my display/monitor. I have selected different prefferences for my monitor to display and the monitor went black, and it shows me a message "Can't display this video preffs, change or cable to...." some 64Hz port, .....something like that. Sorry, I am not too much of a computer person. Can anybody help me with this? I did restart the computer, and no changes.....can't change the display to the previous settings cz ......there's nothing on the monitor except that message...
