SYMPTOMS

After you install or upgrade to Windows 2000, you may lose the capability to use high resolution screen settings in your Display properties.

CAUSE

This issue may occur because of an effect called mode pruning.

RESOLUTION

To work around this issue, verify that the monitor selected is the correct monitor you are using with your computer. To do this:
  1. Click the Start menu, point to Settings, point to Control Panel, and then click Properties.
  2. Click the Settings tab.
  3. Click the Advanced button.
  4. Click the Monitor tab.
  5. The monitor selected for your computer is displayed in the Monitor Type section.
If the monitor displayed in the Monitor Type section is not the monitor you are currently using:
  1. Perform the steps above, and then click Properties.
  2. Click the Driver tab.
  3. Click the Update Drivers button.
  4. Click Next after the Upgrade Device Drive Wizard starts.
  5. Click the Display a list of the known drivers radio button, and then click Next.
  6. Click the Show all hardware of this device class radio button. This provides a list of monitor manufacturers and models.
  7. Select the manufacturer of your monitor, and then select the model from the left-side pane.
If your monitor is not listed, you may want to select a (Standard monitor type) from the top left-side pane. Then choose from the right-side pane the most compatible setting to match your monitor.

NOTE: Incorect settings can damage your monitor. Please refer to the documentation included with your monitor if choosing the (Standard monitor type) setting.

You may also want to verify that the video card driver was correctly identified. To do this:
  1. Click Start, point to Settings, point to Control Panel, and then click Display.
  2. Click the Settings tab.
  3. Click the Advanced button.
  4. Click the Adapter tab.
  5. The video card selected is displayed in the Adapter Type section.
When you click the 'List All modes' button, a list of what functionality is inlcuded with this video card is displayed.

Different video cards use the same video chipset, and the video adapter manufacture adds extra features to the cards. For more information about updates to your video card and new driver information, contact your video card's manufacturer.

STATUS

Microsoft has confirmed that this is a problem in Microsoft Windows 2000.

MORE INFORMATION

Mode pruning is a method by which a list of supported capabilities of a video card is reconciled with a list of capabilities of the monitor.

For example, if a video card supports many display modes (for example, width, height, color depth, and refresh frequency), but the connected monitor is not able to display all of these modes, the operating system queries the capabilities of the monitor. The returned mode capability list from the monitor is applied to the mode capability list generated from the video card and is then pruned to include modes correctly supported by the monitor.
