  5. Does it have control center? If so go to advanced and set it to automatically detect the monitor on startup.
  6. I set to automaticaly detect but no change...

    After reboot adapter properties show 1680x1050 but the real resolution detected of monitor is 1440x900

    I change this resolution to any else >>> appear the screen :

    "Do you want the keep this settings" >> I say: NO >> now the resolution becomes good ( 1680x1050 )


    Is error of video card, monitor or software ???
