RGB to DVI(/VGA) converter
Using flat screens (TFT)
For a long time, RGB and EGA/MDA/CGA
have been popular graphic standards for
industrial applications. In the RGB interface,
three (coaxial) cables carry the colour
information: R (red), G (green) and B (blue). In
addition, the green signal carries the
synchronization signals HSYNC and VSYNC.
In the EGA/MDA/CGA interface TTL signals
are used.
Compared to usage of a CRT monitor, it is
considerably more difficult to use a TFT
screen with RGB signals. TFT screens must
digitalize the incoming video signals and
display the result. To do this, the monitor
needs the exact count of pixels per line and
the phase of the pixels. However, even if you
strip the sync signals from the green signal
and convert it to a TTL signal, there is the
same problem as with VGA screens: the sync
frequencies are to slow for modern displays.
Additionally, many flat screens only operate
with the so-called VESA resolutions.
Nowadays, displays for RGB sources are quite
hard to get – especially if the customer wants
to get the benefits of a flat screen. Clearly,
there is a need to convert RGB/TTL signals for
the modern graphics interface.
Why is it not possible to simply attach a DVI or
VGA screen to a RGB source/TTL?
A screen designed for VGA cannot normally
display RGB/TTL signals for two reasons:
1. A VGA screen requires H/V-synchronization
as TTL signals
2. Many RGB/TTL sources generate HSYNC
frequencies below of 30kHz – to slow for
modern VGA displays.
To display RGB/TTL data on a modern VGA
or DVI display, the RGB to DVI(/VGA)
converter digitises the incoming signals, stores
them in an internal video memory and displays
them from there in a common resolution. The
picture can be displayed in original size or
format filling. The RGB to DVI(/VGA) converter
is equipped with various automatic and
manual video correction tools in an on screen
utility
How does the RGB to DVI (/VGA) converter
solve these problems?
This device converts the signals of a RGB/TTL
source in a format that can be shown on both
a traditional CRT with VGA connector (using
an adaptor) as well as on a flat screen with
DVI connector.
The device digitalizes the incoming video
signals and stores them in an internal video
memory. From there they are displayed in a
compatible, user selectable format: 640x480,
800x600, 1024x768 or 1280x1024, with 75Hz
or 60Hz refresh rate. Before displaying, the
picture can be stretched to fit to the screen
size: 1:1 in a black box; fully fitting to the
screen size; fitting one dimension with the
other scaled appropriately; or at a fixed 2:1
stretch factor.
