Have you confirmed that your video card can support 16-bit colour?

If so, then you need to check that the correct drivers for the video adapter
card are installed. If you have only generic VGA drivers you will not get
16-bit colour

The solution is to find and install the correct video display adapter
drivers for your card. There may have been a CD of drivers provided with
the machine (or with the card, if you bought it as an upgrade). If not, you
may be able to download the correct drivers from the video display adapter
manufacturer's www site, or from the www site of the machine manufacturer
(if the display adapter is part of the motherboard).
Otherwise, you may be able to get a suitable driver from any of the driver
download sites, or you could use a generic driver from the www site of the
video display chipset manufacturer. Software such as Everest can detect the
type of hardware you have installed.

When you get the correct drivers, follow the manufacturer's instructions for
installing them. You should then have access to all the display modes that
your hardware supports.

Note that this problem is not a monitor or monitor driver problem - it is a
problem with the drivers for the display adapter - the device that actually
generates the video signal.
