You did not say which version, so I will assume it to be 11. Also, it would have been helpful to know what the monitor, the video card, and the drivers.



To adjust the video settings:



1. Click the Now Playing Tab along the top of the Window.



2. On the View menu, point to Enhancements, and then click Video Settings.



3. In the Enhancements pane, move the Hue, Saturation, Brightness, and Contrast sliders to the settings that you want to use.



Note:

---------

To hide the video settings, click the Close button in the Enhancements pane.
