AC2 Display question

[bob]

I just installed AC2 on a DS10, ATI 7500, Dell P1110 mon.
Install is fine, BUT It did not recognize my monitor, and did not give 
me a chance to select the monotor. Probably something I did.

Can someone point me to the docs on how to change the monitor setting?
or tell me what I might have missed on the install?
thanks!
