Monitor's native resolution not showing up in Display properties

chernavsky used Ask the Experts™
I have a flat-panel Dell monitor (model E198WFpv) with a native resolution of 1440 x 900.  I have it connected to a Dell Optiplex 210L desktop computer with Windows XP Pro SP3.  There is no additional video card -- I'm just using the stock hardware that came with the computer.  The adapter shows up as Intel(R) 82915G/GV/910GL Express Chipset Family.

Everything worked fine until I temporarily swapped out the flat-panel for an old CRT monitor.  I adjusted-down the resolution when I used the old monitor.  Now that I've re-connected the flat-panel to the PC, I can't set the display settings to the monitor's native resolution -- 1440 x 900 doesn't appear as one of the choices.  I've tried re-booting.  I've tried scanning my hardware for plug-and-play devices. I also downloaded and installed Dell's driver, which seemed to have no effect whatsoever.

I've also tried Display -> Settings -> Advanced -> Monitor -> List all modes.  It's not in the list.

What am I doing wrong, here?  And how do I fix it?

I recommend you uninstall and reinstall your video driver.

Go to Device manager and delete the Monitor and restart your PC. You don't have to restart the PC since you can just refresh the hardware list, but I always restart the PC.
I agree with Thalarctos.  Weird it would do that, but that's what I would try first.

You need to "tweak" the static settings for the 910GL

Not sure what worked -- I kept tweaking everything, rebooting endlessly, until I solved it.  It's back to normal now.  Thanks go out to everyone.
