Hi. My laptop Dell Latitude D630 screen has divided into 6 parts. I thinking that's the problem of hardware. The screen resolution 800x600 and its unable to increase the size. Also unable to connet with monitor and projector etc. The other hardwares are working okey. When this problem occured I turned off it and change the video source VGA to dock display in BIOS settings. Then it became okey. But few hours later it has started divide and didnt turn back to normal. Please help me. I will thank for any solutions and ideas :)
If the system has nVidia video, the chip is known to be faulty. Dell has a 1-year warranty extension on the video chip - if the system is less than two years old (or you had a 2- or 3-year warranty on it at purchase) have Dell replace the mainboard.
