Well, that could be either the memory or color depth.  Looking at the
Dell site, that monitor setting should be OK.

It's in /etc/X11/xorg.conf, in the "Device" section.  Add a line in
the section about your video card:

	VideoRam  RAM-size-in-kilobytes

Again, based on the Dell site, you can have 32M, 64M or 128M of video
RAM.  Select one of these lines to stuff in there:

	VideoRam   32768
	VideoRam   65536
	VideoRam   131072

You may also need to change the "Screen" section and either change or
add the "DefaultDepth" parameter.  It specifies the number of bits used
for each color on the screen and is usually a value of 16 (thousands of
colors) or 24 (millions of colors).
