valuable system resources and results in better playback performance.

color properties to 16-bit color, as follows:
1. Right-click on a blank area of the computer desktop, and then select Screen resolution.
2. Select Advanced Settings > Monitor tab.
3. Click High Color (16 bit), if this setting is not already selected.
4. Click OK.
