Q: Why is the TV not displaying portions of the display when
converted?
A: Your display might be running in “Overscan” mode (placing portions
of the picture beyond the boundaries of the screen’s visible area). This
typically occurs because VGA graphics have more display lines than the
TV can handle. Toggle through the H-SIZE and V-IZE settings in the
MENU until you find the optimum setting for your application.
NOTE
The SIZE control allows the entire image to be displayed by reducing it
and putting a crisp, black border around it. Use this control in
situations where edges of the image would otherwise be lost due to
overscanning.
Q
: There are noise lines on the TV picture. How do I
g
et rid of
them?
A: There are four settings in most televisions that affect the clarity of
the display. The same ad
j
ustments can be used to improve the clarity
of the display whether you use a converter or not. The settings are:
1. BRIGHTNESS: Typically, the brightness setting is by default too
high. A high brightness setting often causes the display to flicker.
2. SHARPNESS: If the sharpness is set too high, often the result is
what is termed “dot-crawl”, where the edges of the image appear
to move. Lower the sharpness to soften the edges.
3. COLOR: If the color is set too high, often the result is colors that
bleed or appear to sparkle. The high (purple) and low (red)
frequency colors are most affected. Adjust the color setting down
to soften the colors.
4. CONTRAST: If the contrast is set too high, often the result is
exaggerated colors. Adjust the contrast down to complement the
Sharpness setting.

Q: I’m not getting a picture on my TV or all I see is a test
pattern.
A: Take these steps:
1. The Y-cable connected between the VGA port on the computer and
the VGA IN/OUT on the Internal Card is backwards. The end of the
cable with the Y-connection should be connected to the
Ultimate
Pro.
2. Make sure the POWER and CHANNEL settings of your TV are
correct. If the TV has a remote control, make sure it is not being
triggered accidentally.
3. Make sure that the correct type of input (VIDEO or S-VIDEO) is
selected on your TV. If possible, connect a VCR, camcorder or
other output device to the TV’s video input and make sure that the
TV is accepting input through the selected connector.
Q: When I connect my TV to the
Ultimate Pro through a VCR,
I get no picture on the TV.
A: Take these steps:
1. Make sure your VCR is outputting on the channel that your TV can
receive auxiliary input on. Consult your VCR’s manual if necessary.
2. Make sure that the VCR is set to receive input from the VIDEO IN
or AUX.
Q: I have DTV, EDTV or HDTV. Can I use the Y.Cb.Cr output to get a
digital display optimized for my digital TV?
A: No. The Y.Cb.Cr output is converting the analog progressive VGA
signal into an analog interlaced signal for display on the TV. The
Y.Cb.Cr output offers the best clarity for scan conversion, but it is not
an analog to digital conversion.

2. Introduction
2.1 General Overview
The VGA to Video Ultimate Pro
is an external high-resolution
computer-to-TV video converter. It transfers images from your
computer for display on a TV or video projector of any size or for
recording on a VCR of any type (VHS, VHS-C, 8mm or Beta.).
The converter is completely hardware based – you don’t have to
run any computer software to use the converter. Its easy
installation and use, features and high-resolution display make it
perfect for presentations, training, kiosks, education, and a host
of other applications.

•Latest generation filter technology brings you clear, 100%
flicker-free video.
•Pure hardware design.
•Supports NTSC, NTSC-EIAJ, PAL-M, PAL-N, PAL, and PAL
Combination-N video for the TV output.
•Zoom function allows areas of the screen to be enlarged for
special emphasis.

5. Trouble-shooting
This chapter tries to answer questions and concerns that can arise
when you install and use the VGA to Video
Ultimate Pro . It also
describes what to do when you have problems with the unit that you
can’t solve yourself.
5.1 Common Questions and Concerns
Q. My TV doesn’t have an RCA jack (composite-video
connector). How can I connect the
Ultimate Pro to the TV?
A1: Check the TV – if it has a 4-pin mini-DIN connector for S-video
input, use this type of video instead (the quality of the picture will be
better anyway).
A2: If your TV is hooked to a VCR, connect through the VCR as follows:
1. Install and interconnect the Ultimate Pro normally, but
connect the composite-video cable to the VCR’s VIDEO IN
jack instead of to the TV.
2. Turn on the VCR and the TV. Switch the TV to the channel
that takes VCR inputs. Play a tape for a moment on the
VCR to make sure that you can see the program on the TV
screen, then remove the tape from the VCR.
3. Consult your VCR’s manual to find out how to set the “input
source” mode for the VCR. (VCRs generally have two or
three input sources: one called TV, CABLE, or TUNER; one
called VIDEO IN or AUX; and occasionally one called TAPE.)
Set the input source to VIDEO IN or AUX. Your TV should
now display the images from the
Ultimate Pro.
A3: Another option is to use an RF-modulator: You can use an RF
modulator (not included) to convert the
Ultimate Pro’s composite-video
signal to an RF signal and send that signal into the TV’s antenna
(VHF/UHF) input. (The quality of the picture will not be as clear as
using only the composite-video or S-video connections directly into the
TV.)

Mac G3/G4 or iMac with CRT port
•VGA monitor (optional for simultaneous display)
•TV, VCR, or large-screen display with composite video, S-
video, or component video input
NOTE:
The VGA to Video Ultimate Pro should support any VGA
computer that has a vertical display frequency between
56 and 120 Hz. However, because video circuitry
connectors and computer display cards differ widely
among manufacturers and devices, we cannot guarantee
that the
Ultimate Pro will function correctly in any
nonstandard application.

Installation (continued)
5. Plug the output cord of the
Ultimate Pro’s power cable
into the DC IN jack on the
Ultimate Pro . Plug the USB or
PS/2 keyboard connector into the corresponding port on
the PC. Macintosh users must use the USB power cable.
6. Insert (2) AAA batteries into the remote control.
7. Turn on the computer.
8. Turn on your TV, VCR, etc. If necessary, select VIDEO IN
(or S-VIDEO IN, COMPONENT IN or RGBS VIDEO IN) as
the receiving device’s video input source. If you’re
unsure how this is done, consult the Owner’s Manual for
the receiving device.
NOTE
Some portable computers require that the VGA output be
activated for the external VGA port to function. If the
Ultimate
Pro is connected correctly and you have a picture on the
receiving TV or projector, this may be the cause. Consult the
User’s Guide that came with your computer if you’re unsure
how this is accomplished. The portable computer’s LCD display
may need to be de-activated with this procedure.

3.3 Installation Procedures
Take these steps to install your
Ultimate Pro :
1. Turn off your computer.
2. Plug the supplied VGA Y-cable (the end with the Y-
connection) into your computer’s VGA output and the other
end into the VGA IN/OUT of the
Ultimate Pro. The ends of
the cable are labeled to specify how to connect them.
3. If using a local monitor plug the monitor’s VGA cable into the
short end of the Y-cable.
4A. If using the
composite video output , plug one end of the
included composite video cable into the
Ultimate Pro’s
VIDEO OUT and the other end into the VIDEO IN on your TV,
VCR, etc. Make sure the output switch is set to CVBS.
4B. If using the higher quality
S-video video output , plug one
end of the included S-Video video cable into the
Ultimate
Pro’s
S-VIDEO OUT and the other end into the S-VIDEO IN
on your TV, VCR, etc. Make sure the output switch is set to
CVBS.
4C. If using the
RGBS video output , plug the DB9 end of an
RGBS cable (not included) into the
Ultimate Pro’s RGB
VIDEO OUT. If the other end of this cable is a SCART
connector, plug it into the SCART connector of your TV,
VCR, etc. If, however, the other end of this cable has four
BNC connectors, plug them into the RED, GREEN, BLUE, and
SYNC connectors of the RGBS VIDEO IN port of your TV,
VCR, etc. If you need an RGBS cable, contact your supplier
for technical assistance. Make sure the output switch is set
to RGB.
4D. If using the
component (Y.Cb.Cr) video output, connect the
included component video cable in the
Ultimate Pro’s Y.Cb.Cr
output and the other ends into the component video input of
the video display. The cable and the plugs are color-coded
for proper connection. Make sure the output switch is set to
Y.Cb.Cr.
