I bought a couple of Dell 2009W displays for our low vision students at school here and I'd like to rotate the display so we can enlarge page views in portrait mode.

We have Dell GX260 machines with the onboard Intel 82845G video adaptor. The information everywhere on the Net talks about using the display driver and selecting the Rotate tab, etc. The latest drivers on the Dell website (2005!) and from Intel don't appear to have the tab available. I cannot find any reference to screen rotation on this computer/adaptor/driver combination.

Can anybody give me any advice on how to enable rotation? Any assistance would be greatly appreciated!
