Multiple Scan 720 Display: Displaying Only One Resolution

I'm using a Multiple Scan 720 Display with a Power Macintosh 9500 which only provides a 640 x 480 resolution with this display. I've reinstalled the software that came with my display and the problem remains. Is this a problem with the display or my Power Macintosh 9500.
There is a known problem with the ATI video cards which are bundled with the Power Macintosh 9500 CPUs which causes only one resolution to appear with the Multiple Scan 720 display. There is a fix in the works from ATI.

A current work around would be to use the ATI software (ATI Displays 1.2 Control Panel, ATI extension 1.1.1, and ATI Graphics Driver 1.0) which can be obtained from their technical website at "http://www.atitech.ca/". You will need to disable the Display Enabler after installing the ATI software in order to obtain all resolutions.

Another work around would be to use an Enhance Cable Technologies Sense adapter. You can reach Enhance Cable Technologies at 800-717-8757. You can order individual cable adapters through MacMall at 800-222-2808.
