About the System’s Video Display
When you start your system for the first time, it uses the Windows NT
Workstation VGA display driver to run the video display. To enable your
system to use its installed GLZ video display adapter, you must configure the
video display to use the Intergraph GL video display driver. This driver is
installed on the system’s hard disk, and is also delivered on a backup
diskette.
The Intergraph GLZ video display adapter is a 3D graphics accelerator.
GLZ provides a number of advanced graphics features, including hardware
acceleration of OpenGL and Windows NT graphics operations. GLZ is
available in several configurations, as follows:
♦
GLZ1 -- 12 MB of frame buffer memory, resolutions up to 1 megapixel
(1152 x 864).
♦
GLZ1T -- same features as GLZ1, with support for texture mapping.
♦
GLZ2 -- 24 MB of frame buffer memory, resolutions up to 1600 x 1280.
♦
GLZ3 -- same features as GLZ1, with support for geometry acceleration.
♦
GLZ4 -- same features as GLZ2, with support for geometry acceleration.
♦
GLZ5 -- same features as GLZ3, with support for texture mapping.
♦
GLZ6 -- 34 MB of frame buffer memory, hardware-accelerated support
for texture mapping and geometry acceleration, resolutions up to 1600 x
1280.
If your system is set up for dual-screen display, the video display driver
treats the combined display area of the dual screens as a single canvas that
covers both screens. In this Full Canvas style, windows centered on the
canvas are split between the two screens. This includes most system dialog
boxes.
When the system is running Windows NT Workstation 3.5 (or later), the
video display driver can treat the left or top monitor as the primary screen,
while the full desktop extends across both screens. This Primary Left/Top
style results in different windowing behaviors than those displayed by
default, including the following:
