SYMPTOMS
When Media Center is running in full-screen mode on your Microsoft Windows XP Media Center Edition 2005-based computer, the screen may go black when you take any one of the following actions:
 * You press and hold ALT, and then you press TAB several times.
 * You change from a supported screen refresh rate, such as 60 Hertz, to a non-supported screen refresh rate, such as 70 Hertz.
 * You change the screen resolution to 1152 x 900, 1152 x 870, or 832 x 624.



CAUSE
This problem may occur in the following scenarios:
 * You press and hold ALT, and then you press TAB several times when Media Center is running in full-screen mode and Media Center is the only program running on the computer. The problem does not occur when there are additional programs that are running and that appear when you press ALT+TAB.
 * The screen refresh rate, or refresh frequency, is not correct. Windows Media Center Edition uses 60 Hertz to optimize the display when in full-screen mode. This is the same screen refresh rate that is used with NSTC video. This problem may occur if the screen refresh rate is automatically changed to a higher frequency when you change the screen resolution.
 * The screen resolution has been changed to a resolution such as 1152 x 900, 1152 x 870, or 832 x 624. Note that when you change the screen resolution, the screen refresh rate may be automatically changed to a higher frequency, which may be incorrect. For more information about this, see the second bullet in this section.



WORKAROUND
To work around this problem, use one of the following methods.

Method 1: The screen goes black when you press ALT+TAB
To work around this problem and restore the screen, either press the Windows logo key, or press CTRL+ESC to open the Start menu. When the screen is restored, you can switch the screen focusback to Media Center.

Method 2: The screen goes black after you change the screen resolution or screen refresh rate
To work around this problem and restore the screen, follow these steps:

 * 2) Click the Settings tab, and then set the screen resolution to a supported resolution by moving the slider bar to the setting that you want.
 * 3) Click Advanced, and then click the Monitor tab.
 * 4) In the Screen refresh rate list, click60 Hertz, and then click OK two times to apply the changes.
