Troubleshooting

Why doesn't my screen display a video?

❑If the display output is directed to the external display and the external display is disconnected, you cannot display a video on your computer screen. Stop video playback, change the display output to the computer screen, and then restart video playback. See Selecting Display Modes (page 69). Alternatively, you can press the Fn+F7 keys to change the display output. See Combinations and Functions with the Fn Key (page 31) for more information.

❑The video memory of your computer may be insufficient for displaying high resolution videos. In this case, lower the resolution of the LCD screen.

To change the screen resolution, follow these steps:

1 Right-click the desktop and select Personalize.

2 Click Display Settings.

3 Move the slider under Resolution to the left to reduce or to the right to increase the screen resolution.

✍

You can check the total amount of the graphics and video memory available. Right-click on the desktop, select Personalize, and click Display Settings, Advanced Settings, and the Adaptor tab. The displayed value may be different from the actual amount of memory on your computer.
