When you try to change the Desktop Area setting in properties for Display,some options that the video adapter is capable of providing may not beavailable. For example, a video adapter that can display 1024 x 768 x 256resolution may offer only 640 x 480 x 256 and 800 x 600 x 16 as theresolution options.
Missing display options can occur when one or more of the followingconditions exists:
The computer is a PCI system and the Monitor Timing settings in the system BIOS are set incorrectly. The Monitor Timing settings should match the capabilities of the display monitor (screen). Check your monitor documentation for the maximum resolution supported by your monitor. Refer to the documentation for your computer system to obtain information about how to make the necessary changes to the Monitor Timing settings.
The Monitor Type is incorrect on the Change Display Settings property sheet. (You can access this setting by clicking the right [secondary] mouse button on the display, clicking the Settings tab, and then clicking the Change Display Type button.) The Monitor Type should match the monitor brand and model that you are using. If your monitor is not listed, you can select the Generic setting that corresponds to the capabilities of your monitor.
The Windows display driver doesn't support the display mode you are trying to use. If you are confident that the display and video adapter is capable of a higher resolution, try setting the Adapter Type to one of the high-resolution generic (Super VGA) modes. NOTE: This may or may not function correctly depending on your configuration.
You are using a Windows version 3.1 display driver. If you use a Windows 3.1 display driver, the Desktop Area and Color Palette settings are not changeable in Properties for Display. To change the resolution, you must click the Change Display Type button and change the Adapter Type to the Windows 3.1 display driver you want to use.
