5160 video problems

  Have new 5160. had monitor problems , contacted dell, after doing checks sent unit to dell depot for repair. only took 2 days to send off, repair and return with new lcd monitor. ( my problem ) first boot up everything seemed fine. Upon checking desplay/ settings they showed one monitor numbered no2 whith resolution at 1p x 1p. hit identify button and lcd screen had no responce. (notice) current settings display drive can not be used, was written for previous version of windows, not able to use with this version. sys started with default vga driver. there is no other moniter on this sys so the lcd is the only one.

 

  By useing fun f8 i then change monitors and the correct setings displayed in display/ settings window showing 2 monitors with no1 moniter being identified with lcd. by rebooting and using f12 i then tried to run test on lcd monitor with only plank screen during test try. hitihg esc bruoght my screen back. test for svga vga all showed they passedwith all test showing on lcd. when shuting down with all setings correct it boots up  without proper setings. my grafic card is 32mb xgi xp5

 

  this is the first laptop i have owned, though i have had and have more that 6 dell desktops with no problems, allmost lol. In sys/monitor display i have 3 default monitors listed is this normal. tried earlier post but did not see it, if duplacting please accept my appoligy.  Thankyou all for your time
