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.

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
interlaced method to display the picture on the screen,
a standard interlaced analog TV will most likely flicker
when displaying thin lines and small text. An interlaced
video display device will produce a lower quality
display, especially when viewing and using the
computer functions.
Progressive scan video displays a video frame with one
pass of sequential scan lines. A progressive scan TV
displays the entire picture, drawn sequentially from top
to bottom, without the odd/even interlacing. This
results in a fuller, sharper picture and better display
quality for viewing and using the computer functions.
The progressive scan picture is also brighter and easier
on your eyes.

Your computer detects whether you are using a VGA or
an S-Video display device and automatically changes
the display settings for the type of display device you
are using. For more information, see the Gateway
