I am trying to setup a secondary monitor on my computer that has a AGP Radeon 9550.
Both monitors work when both are made primary. The one that displays is directly on the D-sub port, the secondary is on a DVI to D-sub adapter.
The primary is a hitachi CM771, the other is a dell ultrascan p991.
Windows and ATI catalyst control center both detect the monitor, and when I check extend my desktop onto this monitor, it just unchecks it again. Catalyst control center won't enable the secondary monitor.
