1.3 Getting the Best Results
There are many factors affecting the quality of results when scaling video signals.
Some basic precautions will ensure the best possible performance from your
Video Scaler.
•Output display device – The quality of the output signal will depend
largely upon the type and quality of display device used. For instance,
some video projectors just look better than others.
•Using Native Resolution – It is always best to set the output
resolution of the scaler to the native resolution and refresh rate of the
display device. This allows our scaler to do most of the work, which
usually results in a superior picture.
•Distance between the Video Scaler and the display device – This
plays a major role in the final result. Long distances are possible, but
special measures should be taken in order to avoid cable losses.
These include using high quality (coax-type) VGA cables and Premium
DVI Cables. Line amplifiers may also be necessary.
•Output connection cables – Low quality cables are susceptible to
interference. They degrade signal quality due to poor matching and
cause elevated noise levels. Therefore, cables should be of the best
quality. Coax-type computer cables are recommended because of
their superior internal shielding characteristics.
•Interference from nearby electrical devices – These can have an
adverse effect on signal quality. For example, an older computer
monitor often emits very high electromagnetic fields that can interfere
with the performance of video equipment in its proximity.

4 CONNECTING THE HARDWARE
The first step is to connect a video source to the input of the Scaler and to
connect it’s output to a display device. The drawing below is common to both
units and shows the locations of the input and power connectors.
4.1 Connecting the Input
Both the 1T-V1280HD-ST and 1T-V1280DVI Video Scalers can accept
Composite Video, S-Video, YUV Component or SCART RGBs Video inputs.
Composite Video is connected to the Scaler via the RCA connector, S-Video
connects via the 4-Pin Mini-DIN Connector, YUV Component connects via the 8-
Pin Mini-DIN Connector using the 3RCA to 8-Pin Mini-DIN Cable provided,
SCART connects via the 8-Pin Mini DIN connector using the 8 Pin Mini-DIN to
SCART Cable, and RGBS connects via the 8-Pin Mini-DIN Connector using the 8
Pin Mini-DIN to 4 RCA Cable provided. Proper signal levels are very important to
the operation of this product so make sure your inputs are of the levels specified
1 Input and Power
Connections

on page 6. If improper operation of the unit occurs and the unit has power, the
most likely cause of the problem is high or low signal levels or the use of a wrong
input cable.
4.2 Connecting the Output
The 1T-V1280HD-ST Video Scaler can output analog RGBHV or YPbPr formats
up to UXGA and 1080p. RGBHV and YPbPr are both available on the HD-15
output connector. Should a HDTV (YPbPr) output be desired, use an HD-15 to
RCA cable to connect the device’s output to the destination device. The 1T-
V1280DVI outputs only digital RGBHV format up to SXGA and 1080i via the DVI
connector.
4.3 Connecting Power to the Unit
The Video Scaler is shipped with an In-Plug Power Adapter to convert
100~240VAC@50-60Hz to 5VDC. Connect the DC Output Cord from the Power
Adapter to the back of the unit and then plug the Power Adapter into an AC
Receptacle. When the unit’s front panel Power Switch is turned On, the Power
LED indicator will illuminate.
5 OPERATING THE UNIT
5.1 Controlling the Scaler
The Scaler is controlled via three buttons with status indicated by OSD. The
position of the buttons is slightly different on the two models but the functionality
is the same.
1T- V1280HD-ST -ST 1T-V1280DVI
•Menu Button: This Button displays the Menu Options via the On
Screen Display on the display device connected to the output.
•+ and - Buttons: These Buttons allow navigation within the Menu and
adjustments of the parameters available.
•XGA Reset: Simultaneously depressing the – and + buttons returns
settings to factory defaults and sets the output to XGA.
•480p Reset: Simultaneously depressing the MENU and - buttons
returns settings to factory defaults and sets the output to 480p.

Pressing the Menu Button results brings up the Initial or Main Menu, as shown in
the following illustration. Move the cursor to the desired setup option by using the
+ and – buttons. When you reach the option you desire, press the Menu Button
again to call up that option.
Once the desired option is reached and selected, a new Menu will appear and
you once again use the + & - Keys to select the parameter you wish to change or
adjust.
5.2 Setup Example
If you select the first item on the main menu, Picture Adjust, a secondary menu
will show the following items:
If you want to change the Color level for example, you would use the + & - Keys,
to navigate to that Item on the Menu and Press the Menu Key again to select that
option. When Color is selected, a sub-menu for the adjustment will appear:
Color 48
Use the + and - Buttons to increase or decrease the value of the setting. Press
Menu again to leave the setting. Move the arrow to Exit and press Menu/Enter

5.4 Advanced Setup
Advance Setup allows you to turn off the Film Mode (3:2 Pull Down), turn off the
OSD (On Screen Display) and set the “No Signal” Display to either Blue or Black.
5.5 System Information
When this is selected, the OSD shows the Scaler’s current Output Resolution
and Vertical Refresh Rate.
6 TROUBLESHOOTING
Other than checking for faulty cables, the only common problem would be
choosing a wrong Output Setting. Make sure the display is capable of handling
the resolution and refresh rate selected and make sure the output format
selected (RGB or YPbPr) for the type of cable being used at the output.
After trying the above suggestions should the problem still persist, contact your
dealer for additional suggestions before contacting TV One. Should the dealer’s
technical personnel be unable to assist you, contact TV One via our support
website: http://tvone.crmdesk.com. Create a technical support request on the
