I've done a bit of Googling and can't find a specific solution to my problem. I'm trying to use Display Changer to create a script that will change my resolution in XP (Dell laptop). Every time it wakes up from sleep, it goes to non-native 1280x768 and I have to manually switch it to 1280x800 via the Intel control panel (the Windows Display panel doesn't have the x800 option).

From within the command line, I can enter the following commands, and it will work perfectly:

Code:
cd "C:\Program Files\12noon Display Changer\"

dccmd.exe -width=1280 -height=800 -depth=max

and it works perfectly. But I can't get that to work as a BAT or CMD file. When I run the file, I see a command window flash quickly, but the resolution doesn't change.

Any suggestions?

I'm confused. So this isn't on a Mac? You're saying your Dell laptop doesn't automatically go to its native resolution? I think you need to figure out the cause instead of dealing with a script. Reinstall Windows or contact Dell for support.

Have you installed the latest Intel graphics drivers?
Do you know what version of integrated graphics you have? Intel have a specific driver set for widescreen monitors, where the EDID for the LCD isn't read properly, which could help you.

Moving on, open a command window first, then navigate to the location of the batch file and run it. This way you will see what the error is which is causing it to fail.

I agree that the latest video driver is essential-but go with the RIGHT driver; Dell has used a lot of different video systems on various laptops, and the one for that particular laptop could be almost anything.

I also agree with seanc about running the batch file from a command prompt after navigating to the batch file's directory. The errors (if any) should be enlightening.

And looking at this from another direction, when you go to the Display Settings (right click on the desktop to get the Properties context menu to do this), go to the Advanced button. One option on the Advanced pane is "what to do when you change settings." Choose the one for "Apply settings without restarting" instead of "Restart before applying..." or "Ask me before applying..." If you already have that selected, choose another option, and "OK" your way all the way out, then go back and reselect "Apply settings without restarting." That should get XP to actually think about the settings. It doesn't happen often with XP, but sometimes it loses track of some settings' values and needs this sort of thing to "refresh" them.

Nope, but I didn't want to join a PC forum just to be the annoying new guy asking a stupid question.

Correct.

It's a work laptop, so I can't reinstall the OS.

Yes (well, they were the latest available when I first tried solving this problem early this year).

Yes - 945GM, video BIOS 1343, driver version 6.14.10.4543

Intel have a specific driver set for widescreen monitors, where the EDID for the LCD isn't read properly, which could help you.

If I go into the "Intel(R) GMA Driver for Mobile" Control Panel, I can select 1280x800 and it works fine. If I go into the Windows "Display" control panel x800 isn't an option.

That's odd. When I drag the batch file into an open command window so that the file's path appears at the command prompt and run it, it works perfectly, but when I double click it, it doesn't work. Could this be a security feature that's preventing me from running batch files?

I went to Intel's website and their wizard said I'm running proprietary drivers. I went to Dell's website for my particular model (Latitude D620) and found its video driver, reinstalled it, and I'm restarting now.

edit: It might be fixed (Display is listing the correct resolution). It seems to be working now, but only time will tell for sure.
