A: Typically this type of setting is provided by the graphics driver, and Windows usually provides the driver with the most basic functionality for the graphics card. You can find the relevant settings in the graphics driver. If there are no related settings, it may indicate that the video card does not support this feature.

In addition, if you use the IE9 browser or the Chrome browser, you can control whether the graphics hardware acceleration is enabled in the browser settings.
