Force displayresolution on Dell Latitude D620

Force displayresolution on Dell Latitude D620

Hi

I wonder if someone has a clue how to force resolution on a computer. My problem is in an installation environment I get the 800x600 resolution when the install is done and the first person logs in. It is the right driver that gets installed but as I say the wrong resolution.

It is a Dell Latitude D620 with Mobile Intel 945 GM/GU Express Chipset Family

Thank in advance

Kjell,

According to your monitor, it wants 1280x800. Use the following DTD registry entry in your .INF file (see the Wiki at http://isnwiki.jot.com/WikiHome/Articles/111111431for details).

BC,1B,00,A0,50,20,17,30,30,20,36,00,30,BE,10,00,00,18,37,01

On a reboot, this should show up as a new resolution for you. If not, it's possible that the BIOS is locking that resolution out,in which case we can tweak the resolution down to 1278x800 or something like that and get around it.
