THE RGB TO DVI(/VGA) CONVERTER
Welcome to the RGB to DVI(/VGA) Converter
Family!
Thank you for purchasing an RGB to DVI(/VGA) Converter! We appreciate your business,
and we think you'll appreciate the many ways that your enhanced RGB Graphic system will
save you money, time, and effort.
That's because our RGB to DVI(/VGA) Converter is all about breaking away from the
traditional model of attaching a new display to an old graphic source. You can encounter
many potential problems in connecting a flat screen to an RGB graphic source – unless you
use our RGB to DVI(/VGA) Converter products! Attach a flat screen to any graphic source
and match the output to your requirements. The RGB to DVI(/VGA) Converter – the one-stop
answer for all your RGB adapting needs! And with a special adaptor cable (not supplied as
standard), you can also attach a screen to a CGA or EGA source.
This manual will tell you all about your new RGB to DVI(/VGA) Converter, including how
to install, operate, and troubleshoot it. For an introduction to the Converter, see Chapter 2.
The Converter product codes covered in this manual are:
