Windows XP will not accept 1600x900 Res for new monitor

Just installed a new monitor on an older Dell Optiplex PC, 20", native res is 1600x900.  I installed the drivers and rebooted, that resolution is not given as an option.  I installed power strip, created the custom res, rebooted and it is still not there as an option.  What else can I do?

What drivers did you update? The monitor or the video card? if you don't have the option it may be either the video card or the monitor or both causing the issue.

I installed the Monitor drivers and verified that the video card had the most current drivers as well.

video card most likely doesn't support the resolution. look for updated firmware and drivers.

Is the monitor listed explicitly by name or is it listed in some generic fashion (e.g. Default Monitor, Plug-and-Play Monitor, etc.)?

>>> older Dell Optiplex   <--- The video card probably does not support this resolution (as also noted by Rad_Tech).  So new drivers on the old card will not help.

whats the model/make on the monitor ?

Are  you sure the monitor can handle that resolution?

The monitors native res is 1600x900.

I thought maybe the PC was old, but it offers res's like 1600x1200 which is higher than what the monitor can take.  It used to have a 19" 4:3 monitor and it took a larger res than 1600x900.
What resolutions ARE available when you slide the resolution slider?

The video card does not support widescreen resolutions unfortunately. The older video cards can support high resolutions but not widescreen. I have an old Dell desktop from 2001 and ran into the same problem when I hooked up a new widescreen lcd. You may be able to find a low power PCI video card that you can install into an empty slot. Check, etc. You'd have to make sure it's compatible, and that the power supply could handle another card. That's the only work around I can think of.
