CHAPTER 6: Troubleshooting Help For more information about Windows Media Center, click Start, then click Help and Support. Type the phrase Media Center in the Search Help box, then press ENTER. The Media Center video display looks bad on your TV Many factors, such as the display type, quality of the video source, type of connection used, quality of video cables, display device screen resolution, size of TV, age of the TV, or the type of TV (interlaced or progressive scan), can affect the video quality significantly: • Display type-The Media Center is best viewed on computer displays. Other types of display devices, including retail TVs, may provide lower quality video. If you did not order a display device when you purchased your computer, a progressive scan display device with a VGA input is the best choice. • Quality of video source-The quality of the video signal coming into the computer has an affect on the video quality. The video displayed from Media Center is only as good as the source video signal. Cable, digital cable, and satellite usually provide better quality than an antenna. • Type of connection used-You can connect the computer video output to a TV. However, the connection type has an affect on the video quality. The Media Center has two video outputs: • VGA-If your TV includes a VGA port, connect the VGA cable from the computer's VGA (monitor) port to the TV's VGA In port for the best quality. Many TVs do not have a VGA port. • S-Video-If your TV does not have a VGA port, but includes an S-Video port, connect the S-Video cable from the computer's 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 computer 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 www.uk.gateway.com. Important Cable connections must be made correctly for optimal video quality. A loose cable connection can lower video quality. 88

CHAPTER

: Troubleshooting

The Media Center video display looks bad on your TV

Many factors, such as the display type, quality of the video

source, type of connection used, quality of video cables,

display device screen resolution, size of TV, age of the TV, or

the type of TV (interlaced or progressive scan), can affect the

video quality significantly:

•

Display type

—The Media Center is best viewed on

computer displays. Other types of display devices,

including retail TVs, may provide lower quality video. If

you did not order a display device when you purchased

your computer, a progressive scan display device with

a VGA input is the best choice.

•

Quality of video source

—The quality of the video

signal coming into the computer has an affect on the

video quality. The video displayed from Media Center is

only as good as the source video signal. Cable, digital

cable, and satellite usually provide better quality than

an antenna.

•

Type of connection used

—You can connect the

computer video output to a TV. However, the

connection type has an affect on the video quality.

The

Media Center has two video outputs:

•

VGA

—If your TV includes a VGA port, connect the

VGA cable from the computer’s VGA (monitor) port

to the TV’s VGA In port for the best quality. Many

TVs do not have a VGA port.

•

S-Video

—If your TV does not have a VGA port, but

includes an S-Video port, connect the S-Video cable

from the computer’s 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

computer 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
