Recipe 3.21. Troubleshooting Video Problems


Problems

  • You suffer from one of the following issues:

  • You receive the following error message:

    Display problems. This program can't continue.

  • Your display flickers or is garbled.

  • You are having a problem with the multiple-monitor feature.

  • Videos or animations do not work correctly.

  • You cannot set the video resolution above 640 x 480 or 800 x 600 with 16 colors.

Solution

Using a graphical user interface

  1. If your video display is illegible when you start Windows normally, start up your PC in Safe Mode.

  2. Click Start, navigate to Settings, and then select Control Panel.

  3. Double-click System, click Hardware, and then click Device Manager.

  4. Click the plus sign (+) to expand Display Adapters.

  5. Double-click the listing for your video adapter driver.

  6. Select the Driver tab, then click the appropriate button based on the action that you want to perform: (view) Driver Details, Update Driver, Roll Back Driver, Uninstall.

  7. Typically you will need to select Update Driver and apply the correct video driver for the specific video adapter in your system, whether it be a built-in adapter on the motherboard or a plug-in (PCI or AGP) adapter.

Discussion

If Windows auto-detected the video adapter you have, or defaulted to Standard VGA Adapter and did not install the proper driver, your display capabilities will lack many features. It is rare that one generic video adapter driver will work for all implementations of a particular video chipset. An nVidia or ATI chip built into your motherboard will have different video BIOS and features and require a different driver than the same chip used on a plug-in video adapter. The wrong driver may not be able to support all of the video memory, scan rate, or color depth features the adapter is capable of. Installing the exact drivers for your video adapter will ensure all of its features and functions are available. Another hint: if the option is available, enable the IRQ for video setting in your system BIOS setup program many video card features require an IRQ assignment to function properly.
