I followed a guide to set up a HP Pavilion DV6000 laptop with a Samsung SyncMaster 712N monitor via VGA as dual monitors side by side. Both resolutions are set to 1024 x 768 (ratio 4:3), but the laptop's screen has a black border on the sides. I would like to have the image on the whole screen.
The laptop's native resolution is 1280x800 (ratio 16:10) and the external's monitor native resolution is 1280x1024 (ratio 4:3).
