Dual-Headed Displays; Control Panel Applet - Asus 3DP-V500TX User Manual

IV. UTILITIES & DRIVERS

Dual-Headed Displays

This Release supports dual-headed displays using two ASUS 3DP-V500TX boards.
The configurations for each board must be identical. In particular they must have the
same amount of VRAM to run dual-headed simply plug in a second board. The
driver will automatically detect the presence of the second board and run dual-headed.
To switch back to single headed operation, remove the second board.
The ordering of the boards depends on the PCI slots they occupy. On startup the
Windows logo will be displayed halfway between both boards. If the left and right
displays are swapped, simply swap the monitor cables connected to both boards.
Note: In this release dual-headed support on NT 4 is not included, only avail-
able for NT3.51

Control Panel Applet

Some of the registry variables, detailed in the next section can be directly changed
by the GLINT control panel applet, accessible through the control panel. This applet
allows both boot-time and run-time control over the configuration of OpenGL and
other applications using the GLINT display driver. Options that are not applicable
to the currently installed graphics board will be disabled (greyed out). The control
panel is split into a number of groups as listed below.
Note, currently it is necessary to have Administrator privileges to run the control
panel applet. This is because it allows updates to the registry which are only allow-
able to a user with administrator privileges.
