Before I installed UltraMon, hardware acceleration worked fine on both the primary and secondary displays. After installing it, however, hardware acceleration/Direct3D is no longer supported on the primary display, but only on the secondary. When I disable the secondary display, Direct3D and HA come back for the primary.
For completeness, I'm running UltraMon 2.7.1 on Win2K, on a GeForce Ti4200, with the DVI out as the primary and the d-sub as the secondary.

Might be related to the mirror driver used by UltraMon's mirroring feature, please try if the problem goes away if you uninstall the mirroring feature.
To do this, go to Control Panel > Add or Remove Programs, select UltraMon from the list, click on Change, then deselect the mirroring feature on the Customize Installation screen. You'll need to reboot the system after making the change.
