I recently hooked up my laptop to my tv to do the multiple monitor function. It worked for a few days, no problem. NOW for whatever reason, my when i log into my windows user id, the screen is totally black and the display on the tv will not work. In other words the computer is fine, its just that i can't do anything because im workin blind. Is there a way to change the setting and disable the multiple monitor option? I just need to get in there long enoug to change that and im sure it'll fix the problem. Any advice?
