modulator to Channel 3 or 4. The modulator then connects
to your television set using the type F (antenna) cable. The
television set needs to be set to the same channel as the
modulator (3 or 4).
Do FOCUS Enhancements Video Converters work with
large screen televisions?
Yes. The size of the television is not relevant to its ability
to display an NTSC signal. Any television that can accept
a composite video signal from a VCR can accept a signal
from your FOCUS Enhancements Video Converter.
What causes colors in the white letters on my television?
This is a characteristic of the NTSC television standard.
Historically, when color was added to black and white
broadcasts, the color information was overlaid on the
black and white signal. Because of this overlay, some tele-
visions become confused and can’t tell whether elements
of the signal are meant to contain color or brightness infor-
mation. This confusion results in color rainbows seen in
the small white letters and some other pictures. These
effects generally are not noticed in broadcast pictures
which have large objects, complex scenes, and motion.
Using an S-Video input with the FOCUS Enhancements
Video Converter will minimize this condition.
Will I see a color picture on the television if I have black
and white laptop?
Yes. If your laptop has a VGA or Macintosh RGB output
port, it will support color operation when it is connected a
color monitor or television.
Will I see the picture on my computer monitor and the
television simultaneously?
FOCUS Enhancements Video Converters provide a VGA
passthrough cable or port that enables viewing of your
television and VGA monitor at the same time. Some older
laptops will not allow simultaneous use of the television
and the laptop screen.
