E.4 SOFTWARE SUPPORT INFORMATION
The NVIDIA Quadro2 MXR graphics card is fully compatible with software written for legacy
video modes (VGA, EGA, CGA) and needs no driver support for those modes.
Drivers are provided with or available for the card to provide extended mode support for the
current operating systems and programming environments such as:
♦ Windows 3.1, 95, 98, 2000, ME
♦ Windows NT 4.0, 3.51
♦ Whistler
♦ Linux
♦ OS/2
♦ Quick Draw
♦ MS Direct Draw and Direct X
♦ Direct 3D
♦ OpenGL
E.5 POWER MANAGEMENT AND CONSUMPTION
This controller provides monitor power control for monitors that conform to the VESA display
power management signaling (DPMS) protocol. This protocol defines different power
consumption conditions and uses the HSYNC and VSYNC signals to select a monitor’s power
condition. Table E-2 lists the monitor power conditions.

Table E-2.
Monitor Power Management Conditions
HSYNC VSYNC Power Mode Description
Active Active On Monitor is completely powered up. If activated, the inactivity
counter counts down during system inactivity and if allowed to
timeout, generates an SMI to initiate the Suspend mode.
Active Inactive Suspend Monitor’s high voltage section is turned off and CRT heater
(filament) voltage is reduced from 6.6 to 4.4 VDC. The Off mode
inactivity timer counts down from the preset value and if allowed
to timeout, another SMI is generated and serviced, resulting in
the monitor being placed into the Off mode. Wake up from
Suspend mode is typically a few seconds.
Inactive Inactive Off Monitor’s high voltage section and heater circuitry is turned off.
Wake up from Off mode is a little longer than from Suspend.
