114 CHAPTER 9: Troubleshooting • S-Video-If your TV does not have a VGA port, but includes an S-Video port, connect the S-Video cable from the notebook's optional S-Video Out port to the TV's S-Video In port. S-Video display quality is usually good for TV images. The display quality for the notebook functions, however, is not as good as VGA output. S-Video display output is not optimized for computer video display. • Quality of video cables-Poor quality or the incorrect type of video cables can cause problems and affect the video quality. Gateway recommends using high-quality video cables that can be purchased from Gateway. Important Cable connections must be made correctly for optimal video quality. A poor cable connection can lower video quality. • Screen resolution-By default, the notebook uses a screen resolution optimized for the LCD screen.

Some small display devices do not make colorful motion video look its best. Generally, video will look better on a larger display device. • Age of the TV-Newer TVs usually have more advanced features, produce a better quality picture, and support higher screen resolutions. The video display will likely be better on a newer model TV. • Type of TV (interlaced or progressive scan) Many CRT (tube) TVs use interlaced video. Interlaced video displays a video frame with two passes of alternating scan lines. The TV screen first displays the video image odd lines one at a time, sequentially from top to bottom, then it fills in the other half of the video image with the even lines. Because most TVs use this
