  1. press windowskey +p to cycle through the output modes
  2. lappy had function button to switch display if it not automatically done...

    Try those button....

    if it not working, u mention power outage try to cold reboot first..
    If it still not working well there maybe some hardware problems....

    THANKS, seems to be working fine now. I am glad I didn't get rid of the other monitor. As you can tell I am a novice at PC's.

    thanks again
