Chapter 6: Troubleshooting • 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. eMachines recommends using high-quality video cables that can be purchased from www.eMachines.com. Important Cable connections must be made correctly for optimal video quality. A loose cable connection can lower video quality. • Screen resolution-Many TVs cannot display the high resolution that your computer's video signal uses, and may shift, scramble, or scroll the picture. For a better picture on a TV display, you may need to lower the computer's screen resolution to 800 × 600 or 640 × 480. For more information about changing the screen resolution, see the "Customizing Windows" chapter in the online User Guide. • Size of display device-Small computer displays for standard computer applications are generally not optimized for motion video playback. Although they offer excellent resolutions and refresh rates, they are designed to make static white backgrounds with black text look readable. 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 Media Center video display will likely be better on a newer model TV. 84

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. eMachines recommends using

high-quality video cables that can be purchased from

www.eMachines.com

•

Screen resolution

—Many TVs cannot display the high

resolution that your computer’s video signal uses, and

may shift, scramble, or scroll the picture. For a better

picture on a TV display, you may need to lower the

computer’s screen resolution to 800

× 600 or 640 × 480.

For more information about changing the screen

resolution, see the “Customizing Windows” chapter in

the online

User Guide

•

Size of display device

—Small computer displays for

standard computer applications are generally not

optimized for motion video playback. Although they

offer excellent resolutions and refresh rates, they are

designed to make static white backgrounds with black

text look readable. 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 Media

Center video display will likely be better on a newer

model TV.

Important

Cable connections must be made correctly for optimal video

quality. A loose cable connection can lower video quality.
