Screen resolution changes at hibernation.

[Guest]

Dell Inspiron 8200 laptop.
XP Home Edition Version 2002 SP2.

Under System Properties, Performance Options, Visual Effects, "Let Windows
choose what's best" is checked.

Under Control Panel, Display, settings, resolution is 1280x1024. Clicking
advanced shows large size DPI (125%).

My physical screen is completely filled with the normal windows desktop
screen. I close the laptop and it goes to sleep. Later I return and open
the laptop. The user select sign on screen appears. It does not fill the
screen. There is about 3/4 inch of black across the top and bottom and about
1.1/4 inches on each side that is not used. All settings described are the
same yet I have lost about 1/3 of the viewing area on the screen which makes
text very small and hard to read. The only way I have found to get out of
this situation is a restart of the computer. I do not have to change
anything, just restart and it comes up with a full screen.

I have found lots of posts concerning problems with screen resolution but
nothing quite like this. If anyone can help, I'll dance at your wedding.

Check that you have the latest video driver from dell. Uninstall and
reinstall your video card to see if it helps.

Also try fn+f7 or fn+f8,cant remember exactly which one, to fill the screen.
