Hi........i have an HP laptop with windows vista...my screen has been damaged and i hooked an old monitor from an old computer to the laptop and i hit the fn and the f4 button and the monitor worked fine. I purchased a new flat screen monitor today and hooked it up and there came a setting on the screen that said change the appearance of you display. I foolishly was tinkering and clicked on show different parts of my desktop on each display or the one that said duplicate my desktop on all displays....im not sure which one i clicked on. The problem is now the fn and f4 button will not work. It will come up on my new monitor in safe mode but i can't find how to change this setting back in my safe mode. Does anyone know what i can do to fix this problem? I tried to backup to a restore point and it restarted and all i got was my wallpaper background with no desktop or no pointing device or anything. It will only let me start up properly in safe mode. grrrrr thanks in advance for anyone that can help me
