DVI - to - VGA Video Scaler

1. Introduction
1.1 General
The SC-DV-2 is a high performance
PC/HDTV scaler that accepts Digital DVI
input and converts it to analog RGB output
(PC VGA or HDTV Component).
The input resolution is automatically detected
while the output resolution and refresh rate
can be selected through OSD menu and front panel push buttons.
The SC-DV-2 Video Processor combines the functions of a video scaler,
scan-converter, and format transformer and is packed into a compact and
durable metal housing with easy-to-use touch buttons.
The controls include input/output setup picture adjustment, H/V phase
adjustment, System information and many other advanced options.
The SC-DV-2 allows you to specify a resolution and refresh rate for its
output. Then it will output a steady (uninterrupted) VGA signal to your
display device at the specified rate regardless of the input. This effectively
allows any DVI switch, such as HRT's SW-DVI-2A or SW-DVI-4A, to
become a seamless switch. The output timing is constant regardless of what
is happening at the input. So when you switch from one input to another,
the display device does not see any interruption in the signal coming to it.
