Try boot to Safe mode, Select LKGC or Last Known Good Configuration. This should restore the resolution that work before you changed it. i_XpUser

boot into VGA mode and set the correct resolution AND frequency supported by your monitor ... 60 Hz i'd say, but reading the manual doesn't hurt ;-) Today's subliminal thought is: 'Calm down ... it's only ones and zeros.'
