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.

2

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 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 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.

3.0 CHECKING PACKAGE CONTENTS

Before attempting to use this unit, please check the packaging and make certain the following items are contained in the shipping carton:

 1x 1T-DVI-VGA Scaler

 1x 100-240VAC AC/DC Power Adapter

 1x User Manual

Note: Please retain the original packing material should the need ever arise to return the unit. If you find any items are missing, contact your reseller or TV One immediately.

Have the Model Number, Serial Number and Invoice available for reference when you call.

4.0

CONNECTING THE HARDWARE

The first step is to connect a video source to the input of the Scaler and to connect its output to a display device. Below you’ll find drawings of the unit showing the locations of the input, output and power connectors.

4.1

Connecting the Input

The 1T-DVI-VGA can accept both PC and HDTV inputs in the DVI format. The 1T-DVI-

VGA will automatically detect the mode and resolution of the PC/HDTV input.

4.2

Connecting the Output

The 1T-DVI-VGA Video Scaler can output a wide variety of Analog RGBHV resolutions.

Use a high quality cable to connect the scaler to a display device.

Note: Proper signal levels are very important to the operation of this product so make sure your inputs are of the levels specified on page 5. 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, use of a low quality cable or the use of a wrong input cable.

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.

5.0 OPERATING THE UNIT

The Scaler is controlled via three buttons with status indicated by On Screen Display.

 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@60 Hz.

Pressing the Menu Button results brings up the Initial or

Main Menu. Move the cursor to the desired setup option by using the + and – buttons. 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.

Auto adjust- When selected, the T1-DVI-VGA will automatically adjust all the parameters to the factory presets.

Exit- Select to exit from the current menu page.

Notes:

 The default output resolution of the 1T-DVI-VGA is XGA@60 Hz.

 The unit has non-volatile memory and memorizes all setting before power off and recalls those setting on next power on however changing output resolution erases all settings.

 At any time, pressing + and - buttons simultaneously will reset the output resolution to XGA@60Hz, and other settings back to factory default values.

6.0 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:
