Install system 1. 2. 3. Connect the RGB to DVI(/VGA) Converter to the RGB (video) source. Connect a display to the RGB to DVI(/VGA) Converter.
QUICK SETUP 1.1 Video Input/Output If possible, always use a DVI output to a monitor from the RGB to DVI(/VGA) Converter, especially with flat screens. This provides the optimum video signal. If you use a VGA output from the RGB to DVI(/VGA) Converter, it must convert the digitized data to analogue values. Similarly, if your TFT screen uses a VGA input, it must digitize the signal from the RGB to DVI(/VGA) Converter.
THE RGB TO DVI(/VGA) CONVERTER 1.2 Command Summary The following table summarizes the remote control buttons and ‘hot’ key command sequences used in system configuration and video tuning on the RGB to DVI(/VGA) Converter.
OVERVIEW 2. Overview 2.1 Introduction VGA is the most familiar of the various graphics data standards or protocols for connecting a display (monitor or flat screen) to a graphic source. For many years, computers have generally connected to a display through a VGA interface. However, with the increased popularity of TFT flat screens, a new standard has been developed: DVI. In DVI, graphic data is transmitted digitally; VGA is an analogue standard.
