2. Overview
2.1 Introduction
The VGA/HDTV Scaler Plus is a high-performance universal VGA / HDTV to
VGA / HDTV Scan Rate converter with a local loop out.
The scaler can output a specified resolution and refresh rate regardless of the
input. Output timing to the display is constant, regardless of the input. When
switched from one input to another, the display device does not see any
interruption in the signal coming to it.
The video processor combines the functions of a video scaler, scan-converter,
and format transformer. The VGA/HDTV Scaler Plus also includes a horizontal
mirroring feature that you can use for teleprompter’s and rear projection
systems.
The VGA/HDTV Scaler Plus features an OSD menu for configuration, picture
setup, system information, and many other advanced options.
2.2 Features
• Any PC or HDTV video signal can be scaled up or scaled down to any
other PC or HDTV resolution.
• Adjustable output frame rate.
• Additional loop-out to bypass signal processing.
• Large Video memory for real-time frame rate capture and conversion.
• Signal format conversion between RGBHV and YPbPr.
• Automatically detects input mode and timing parameters.
• Allows adjustment of sampling clock, phase, and position on screen.
• Easy-to-use push buttons and OSD menu control.
• Horizontal mirroring (X-Axis Flip)

3. Installation
3.1 Connections
The VGA/HDTV Video Scaler Plus accepts both PC and HDTV input and
output.
Use the HD15 to YPbPr/3 RCA cable to convert YPbPr for HDTV devices.
The scaler includes a display local loop out connection labeled “Bypass
Output.” Use this connection to send a non-processed signal to a secondary
display.

4. Configuration & Operation
4.1 Input and Output
See figures 2-1 and 2-2 above for information about the connections
4.2 Menus and Adjustments
Pressing the Menu button will bring up the OSD menu controls on the screen.
Use the up and down arrows to get to the desired item, then press MENU to
select and enter the submenu. Select EXIT from a submenu to go back to the
main menu or from the main menu to exit the OSD.
CONTRAST
Adjusts image contrast. Range is 0-100%, default=50 (RGB) or 43 (YPbPr)
BRIGHTNESS
Adjusts image brightness. Range is 0-100%, default=47 (RGB) or 54 (YPbPr)
FINETUNE
For RGB Video Input
PHASE - refers to nanosecond timing position of each sample taken. This
adjustment can be used to align the pixels grabbed by the SC-VGA-2B to
those created by the video source. Range is 0-100%, default=73
CLOCK - changes the number of samples per display line. The unit samples
the video at the nominal pixel rate. For example a 1024x768 resolution signal
is sampled 1024 times during the active video time. Changing the clock has
the effect of adjusting horizontal size of the displayed output. When you
change this setting; the right edge of the video moves to the left (shrinking the
width) or to the right (expanding the width). Range is 0-100%, default=50
H-POSITION – Shifts image right and left. Range is 0-100%, default=50
V-POSITION – Shifts image up and down. Range is 0-100%, default=50
EXIT – Exit FINETUNE Submenu

selected resolution. Default
PC – Forces the input video source to be RGBHV
YPbPr – Forces the input video source to be YPbPr
OUTPUT
Use arrows to adjust output mode. Refer to Section 5.2 below for a list of all
available modes.
The default output resolution of the SC-VGA-2B is XGA @ 60Hz.
The unit has non-volatile memory and memorizes all your settings before

5. Troubleshooting
There are no field serviceable parts or circuits in the device. If you think that the
device is malfunctioning (or you have no picture output), first try to reset to factory
default settings. Select FACTORY RESET from OSD menu or Press and HOLD the
MENU button while plugging in the power supply.
Some display devices may become confused and display the output video shifted or
with odd colors if the display device receives BOTH the RGBHV Sync signals as well
as the YPbPr Sync signals at the same time.
This can be caused by using the HD15-HD15 cable on the VGA/HDTV Scaler Plus
output but setting the unit to output YPbPr resolutions (480p for example).
Use supplied HD15 to 3 RCA to make sure that only the desired YPbPr sync signals
are sent to the display device.
5.1 Contacting Black Box
