Quick Help

Once you have installed your XGA device driver, the Windows Control Panel will

allow you to change the XGA display setup within the Windows environment.

1)  While running Windows, double click on the Windows 3.1 Control Panel icon.

    Now execute XGA Setup by double clicking on the XGA Setup icon.

2)  If you have more than one XGA or the display listed is incorrect, click on

    the Display... button to bring up the XGA Desktop Display Selection window.

    Select from the display pulldown list your appropriate display or the

    appropriate setting for your display. If you have multiple XGAs in your

    system, then select the appropriate display connected to each XGA. Select

    the slot with the XGA you want to use for the Windows desktop (primary

    display). Slot 0 indicates an XGA on the system board. Press the OK button

    to return to the XGA Setup window.

3)  Select the desired resolution for Windows 3.1. You will be presented with

    all the valid resolutions for your display type and XGA hardware.

    Resolutions other than 640x480 and 1024x768 are available on XGA-2 Display

    Adapter only. (Note: An incorrect display selection above can produce

    resolutions which your display can not physically support.)

4)  Select the desired number of colors for the Windows desktop. You will be

    presented with all the valid number of colors for the selected resolution.

    A grayed-out number of colors option means that this particular selection

    is possible for the current display but a different (lower) resolution

    must be selected first. The 64K color option is only available with an XGA-2

    Display Adapter.

5)  Select the desired font size for the Windows desktop. The default is

    small size font at resolutions of 800x600 and lower and large size font

    at resolutions above 800x600.

6)  If for some reason you want to change the frame rate (vertical refresh

    rate), push the Advanced... button which appears on the right-hand side of

    the XGA Setup window. It is not recommended that you use this option

    unless you have a specific requirement in mind. You will be presented with

    all the valid frame rates depending upon the selected resolution. Selecting

    a different frame rate could possibly change the number of colors. The

    initial default frame rate is the highest refresh rate available for the

    selected number of colors and resolution. A higher frame rate will result

    in less display flicker.

7)  Click the OK button to save any changes. If changes were made, then a prompt

    will appear. Select Yes to restart Windows to have the XGA settings take

    effect immediately or select No to have the XGA settings take effect the

    next time you startup Windows 3.1.

    Click the Cancel button to discard any changes made within XGA Setup.

Note:  When changing displays, first follow the above steps, and then connect

a new display.  If your Windows display comes up out of sync, first try

deleting the file XGASETUP.PRO in your XGA$DMQS directory.  If you still have a

problem, run Windows setup.exe and select the IBM XGA V2.10.  Then you

can follow the above steps to configure your display.

Setup Version
XGA Setup Version

This help file was written for XGA Setup Version 2.10. The XGA Setup Version 2.10 utility was written for IBM's XGA Windows 3.1 device driver which appears on the XGA Version 2.10 device driver diskette.


Display Setup
XGA Desktop Display Selection Dialog

This selection allows you to override your display type and to select your primary Windows startup desktop.

If you have an IBM PS/2 display, it will automatically be recognized and used to its best capability. If you do not have an IBM PS/2 display, this function will allow you to utilize the resolution capabilities of the IBM ValuePoint 63xx displays andmostnon-IBM displays. Most of these non-IBM PS/2 displays respond as an IBM 8514 display when queried by the software supplied with the XGA-2 graphics subsystem. As a result, IBM 8514 non-interlaced resolutions and refresh rates are used as default.

Changing Colors
Changing Display Mode Number of Colors

All of the number of colors for the currently selected resolution appear as a radio button in the box titled Colors. The currently selected number of colors will have its radio button filled. A radio button will be grayed out if this particular configuration does not support this number of colors with the currently selected frame rate. A radio button will not appear at all if the currently selected resolution doesn't support this number of colors.

To change the current number of colors:

1. select the radio button next to the corresponding desired number of colors

2. make any other display characteristic changes

3. select the OK push button to record the changes

Note: the number of supported colors will vary depending upon the selected resolution and selected frame rate. To possibly get more colors, select a lower number frame rate. The frame rate list box will appear when the Advanced... button has been pressed.


Changing Font Size

All of the font sizes will appear next to a radio button in the box with the Font Size heading. The currently selected font size will have its radio button filled.

To change the current font size:

1. select the radio button next to the corresponding font size

2. make any other display characteristic changes

3. select the OK push button to record the changes

Note: the different font size selection is independent of resolution, number of colors, and frame rate. Therefore, it can be changed without regard to your other selections.


Changing Frame Rate

Warning: Overriding the default with a resolution that does not meet or exceeds the supported resolution, can yield unpredictable results. Some multisync displays might appear to function correctly; however, damage might occur over time.

The IBM XGA-2 graphics subsystem and certain IBM displays have been certified to meet the International Organization for Standardization (ISO) standard 9241/2. IBM cannot guarantee that all original equipment manufacturer (OEM) displays attached to the XGA-2 subsystem will provide acceptable display quality or meet other health and safety standards.
