The image on a TV is always a little too blurry for my taste, and the
quality of a VGA image is very superior.
I had always dreamed to be able to use my SNES on a PC monitor, but
the SNES did not have a VGA output. When I learned that the Dreamcast
could output a VGA signal, I installed a VGA connector on it almost
How it works
Simple. The dreamcast can output VGA from it's A/V output it the rigth pin
is connected to ground. This is usually done by a VGA box.
I found the pinout of the A/V connector and a schematic for a VGA box. Instead
of building the circuit in an external box, I decided to build it inside the dreamcast.
I have been asked a few times one which side should the negative pin of the capacitors
go. They must be on the VGA connector side. The same rule apply for the S-Video output.
I used 1N4148 diodes.
Here are a few pictures of my VGA Dreamcast.
Sonic on a VGA screen. The details are very sharp on this monitor.
I installed the connector on the side of the console. The switch
selects between VGA and NTSC sync frequencies.
An SNES emulator for dreamcast. It is not very fast yet.
This is the place where I soldered the wires. If you do this,
I hope it's not the first time you use a soldering iron...
