Forums -> Multiple monitors -> Dualhead cards and true multi-monitor support on Windows 2000

hi!

unfortunately I have to stick to the detonator 12.60 driver for some strange openGL problems with any other version when using the "enable advanced multimon" feature.
does anybody know if there is a workaround to get true multimonitor support with this driver?
thanks

>Dualhead cards and true multi-monitor support on Windows 2000
Due to a limitation in Windows 2000, dualhead cards that use a single chipset to drive both monitors require special workarounds in the driver to be properly recognized by the system. If these workarounds are not implemented, Windows 2000 sees a single large monitor instead of two.

This causes the following problems:

using different resolutions for each monitor is not possible
windows are maximized to the desktop instead of the monitor they are on, and dialog boxes appear centered on the desktop, split across monitors. Software included with the card may be used to work around these problems though
taskbar is extended across both monitors instead of only a single one
multi-monitor software will not work properly
The latest drivers from Appian, Matrox and Nvidia have full Windows 2000 multi-monitor support for the following dualhead cards:

Appian Hurricane
Matrox G400/G450/G550
Nvidia dualhead cards (with Nvidia driver version 28.32 or later)
The following cards don't have drivers which implement the necessary workarounds, and so exhibit the problems mentioned above:

Appian Gemini
ATI RADEON dualhead cards

or has anyone maybe successfully added the "enable advanced multimon" registry key in a newer version of the detonator driver?
