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 image,
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 image quality for
viewing and using the computer functions. The
progressive scan picture is also brighter and easier on
your eyes.
