Thanks Ron, a good point I failed to mention.

Just to expand a bit on this.

The available colour depth can also be dependent on the screen
resolution setting if there is only a small amount of video RAM
available.

For example, if your video card has only 8 mb of RAM you may only be
able to get 16 bit colour if you have the resolution at 1600 x 1200
but if you decreased the resolution to 1024 x 768 then you would get
32 bit colour available as well. This is not something that is
encountered very often today with the larger amounts of video RAM
being used but it was a concern with older systems.
