refresh rates, they are designed to make static

advanced features, produce a better quality
picture, and support higher screen resolutions.

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 notebook 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 Media Center functions.
The progressive scan picture is also brighter and
easier on your eyes.
