2.0 INSTALLING THE DISPLAY DRIVERS
__________________________________
The Windows 3.1x device-driver installation program, called
INSTALL.EXE, must be run from Windows to install the new video
device drivers and utility programs. All video device drivers and
support files are copied to Windows subdirectories, and the utility
programs are copied to the drive and directory of your choice.
Messages that are displayed in this program automatically appear in
the same language that Windows appears in. For languages that are
not supported, English appears. At the end of the installation, the
WinMode utility program is run to complete the new device-driver
setup. This utility program allows you to configure your graphics
system for Windows 3.1x.
To run the installation program: first start Windows 3.1x.
1. Start Windows 3.1x and select the Main icon.
2. Click on the Windows Setup icon, click on "Options," and then
click on "Change System Settings." Under "Display," select VGA,
and then select OK. Under "Change System Settings," select
"Current," and then select "Restart Windows."
3. Insert the Windows 3.1x graphics-accelerator device-driver
installation diskette into your diskette drive.
4. From the Windows Program Manager select the Run command from
the File menu.
5. In the Run dialog box, type the diskette drive letter and
"INSTALL" (without the quotation marks) in the command line
field. For example, type a:\install.
6. Press Enter or click on OK. An hourglass icon indicates that the
program is being started. Note that driver installation must be
performed while in VGA mode of operation.
7. If an Install Program or Verify Destination dialog box is
displayed, select "Continue" or "Install."
8. In the "Select a Group" window, select OK to select the default
(VGA Utilities) Install group. Under "Installation Complete,"
click on OK.
9. A WinMode screen is displayed after the device driver is
installed. Select the monitor brand, monitor model, monitor
refresh rate, number of colors, resolution, and font size, and
then select OK.
10. If you see a "Change AUTOEXEC.BAT" dialog box, select "Make all
Modifications for you." The monitor selections you make will be
saved as the default selection for system startup.
11. Remove the installation diskette and restart Windows.
12. Select the WinMode icon that was created during installation to
change the display options.
3.0 CHANGING YOUR MONITOR CONFIGURATION
_______________________________________
The WinMode utility program configures your graphics system for
Windows 3.1x. It allows the you to change the monitor refresh
rates, resolution, number of available colors, large or normal size
fonts, and font cache size. After new options have been selected,
you can either immediately restart Windows, in which case the new
resolution takes effect immediately, or continue working in the
current resolution, in which case the new resolution is effective
the next time Windows is started. In some configurations, the
AUTOEXEC.BAT file must be modified to make the changes permanent.
WinMode assumes that the Windows device drivers have been correctly
installed and configured using the installation utility program
provided on the Windows 3.1x Drivers and Utilities Diskette. To run
WinMode, select its icon. The icon is in the group that you
specified during the installation process. When WinMode is started,
the screen may blank for up to two seconds while WinMode attempts to
determine the capabilities of the monitor. If this is successful,
you see only one choice besides the other brand and model choices in
the Monitor Brand and Monitor Model drop-down combo boxes.
The VESA Display Data Channel (DDC) protocol is supported by the
video subsystem. This device driver automatically detects DDC
monitor capabilities and sets the monitor to the maximum refresh
rate supported by the monitor.
3.1 Monitor brand and model
Select the brand of your monitor from the list provided in the
drop-down box. This changes the list of monitors in the Monitor
Model drop-down box to display only the models that are available
under the selected brand. If your monitor brand is not listed,
select "Other Brand."
3.2 Changing Color Depth
The Color buttons let you choose the number of colors that are
available to WIndows 3.1x after Windows is restarted. Some of the
choices might be unavailable, because of the amount of video memory
in your system and the resolution that you have selected.
Generally, 256-color mode is the fastest choice. If you use more
colors, there is some slowdown in graphics performance.
3.3 Monitor Refresh Rates
The drop-down list boxes let you select the monitor refresh rates
for each resolution. If you select "None" for any screen
resolution, any higher resolutions are also unavailable. This also
turns off the corresponding choices in the "Resolution" box. In
general, the higher the refresh rate, the better the display quality
and the lower the performance, because the graphics system can
perform only a fixed number of operations per second. The more time
it spends redrawing the screen, the less time it has available to
perform other operations. Refer to the manual that comes with your
monitor to determine the proper settings for these fields.
3.4 Font Size
The small fonts are intended for lower resolutions and for higher
resolutions on large monitors. With smaller monitors, the large
fonts are more readable at higher resolutions.
4.0 Reconfiguring Windows 3.1x
______________________________
If you are in Windows, run WinMode to reconfigure the Windows 3.1x
device drivers. If you are in DOS, proceed as follows to reconfigure
the Windows 3.1x drivers:
1. Ensure that Windows 3.1x and the extended resolution drivers are
already installed on your computer.
2. From your Windows directory, at the DOS prompt, type SETUP, and
press Enter to run the Windows SETUP.EXE program. Follow the
instructions on the screen. When you come to the screen that
lists the hardware and software components such as video adapter,
(such as VGA or CGA), keyboard type, and mouse type, go to the
Display selection by using the up-arrow and down-arrow keys to
move the highlighted bar. Press Enter.
3. You see the list of device drivers and their associated
resolutions.
4. Highlight the desired choice by moving the cursor to the correct
video driver, and then press Enter.
5. Setup prompts you that the driver is already in your Windows
directory and gives you a chance to replace it. Use the existing
device driver.
6. Continue with the remainder of the setup procedure, Monitor
Refresh Rates.
5.0 TURNING DDC DETECTION SUPPORT ON AND OFF
_____________________________________________
To turn the DDC detection support on or off, make the following
changes to the WINMODE.INI file.
To turn on DDC detection support:
MakeDdcCall=on
To turn off DDC detection support:
MakeDdcCall=off
6.0 POWER MANAGEMENT SCREEN SAVER
_________________________________
The Display Power Manager for Windows 3.1x provides a mechanism to
control the amount of power used by the monitor. It provides a
total of five levels of power savings. The first level is a
conventional screen saver that turns the screen black and bounces a
logo around. The black screen provides substantial power savings,
and the animation lets you know that the computer is still active.
The other four levels of power savings are:
Reduced on mode
Stand-by mode
Suspend mode
Off mode
Off mode provides the highest level of power savings, matching the
power-saving modes defined by the VESA VBE/PM standard. As you move
down from one mode to the next, the amount of power saved is
greater, but so is the amount of time that it takes for a monitor to
recover and be ready to display data.
The screen saver cycles through all of the selected power-saving
modes, one after another, until the maximum selected power-saving
mode has been reached. The number of minutes that is specified for
each level is the number of minutes since the previous mode was
enabled, not the total time elapsed.
1. Using the Windows Control Panel, select "Desktop."
2. In the Screen Saver group within the Desktop dialog box, select
the Screen Saver named Display Power Manager.
3. Select the desired delay before a power-saving mode is entered.
4. Select Setup to further configure the power saving options. The
following sections describe these options. For further
information about setting up Windows screen savers, refer to the
Windows User Guide.
Specific display types
Some of these power-saving modes are intended for specific monitor
types, so not all of them are available on all video controllers.
On some controllers, only the animated logo is available. For the
power-saving modes to have any effect beyond just blanking the
screen, the monitor being used must have specific power-saving
features.
Note: If the screen saver is in any of the power-saving modes,
moving the mouse does not wake it up. This is different from normal
screen savers and is used to keep the monitor from waking up because
of accidents such as bumping the desk that the computer is sitting
on. This is especially important if the password option is enabled,
because when the password dialog box pops up, it stays there until
the user turns it off. This is a limitation of the Windows 3.1x
screen-saver interface.
Using the Screen Saver
When the screen saver is started, it initially displays a bouncing
logo on a black background. To enable additional levels of power
savings, select them from the Screen Saver Mode section of the Setup
dialog box.
