9.12 IBM XGA; Configuring Color and Resolution Windows Setup will automatically configure an IBM XGA for 16-color, 640x480 resolution. If your monitor can support 256 colors or higher resolutions, you can configure your XGA to use the color and resolution settings you want. To do this, run Windows Setup from the Main group, and then select one of the following drivers from the list of Display options: . XGA (640x480, 16 colors) This is the default setting and should not be changed if you are using the plasma screen on the PS/2 model 75. . XGA (640x480, 256 colors) . XGA (Small fonts) . XGA (Large fonts) Both the Small and Large fonts settings configure the XGA for 1024x786 resolution and 256 colors, if your monitor supports it. Otherwise these settings configure your display for 640x480 resolution. Select Small Fonts if you have a large monitor (at least 16 inches) or want to fit more information on your screen. Select Large Fonts if you want to improve the readability of text. Make sure that your monitor supports the XGA configuration you select. If it doesn't, you will be returned to the MS-DOS prompt when you try to start Windows. For more information on using Setup after you have installed Windows, see Chapter 15, "Maintaining Windows with Setup," in the Microsoft Windows User's Guide. .
