Since M1-DA to VGA cable is quite expensive, we have decided to add extra connector to our Dell 3400MP Projector so we could just use common male to male VGA cable.
1st thing to do is to know the connector pin-out. For VGA connector we have 15-pin connector.
Cable = MALE and Projector = FEMALE.
Next, the M1-A connector (AKA M1-P&D Plug) A lot of pin. :-)
Cable = MALE and Projector = FEMALE.
Internet research tell me that only 7 connections are needed in order to make this work as below
>  |  | |
| VGA pin# | M1 pin# | |
| Red | 1 | C1 |
| Green | 2 | C2 |
| Blue | 3 | C4 |
| RGB Ground | 6,7,8 (join) | C5 |
| Horizontal Sync | 13 | 5 |
| Vertical Sync | 14 | 6 |
| Sync Ground | 10 | 4 |
Now the hard work begin.... disassembling...
Soldering...
Testing...
Finally, the connector cut-out through the Dell 3400MP magnesium alloy chassis.
Final test.

Well I can't tell you how it will make the dreamcast look but I can tell you definitively that VGA cabling offers clearer and higher resolution output than a SCART, RGB, coax, composite, or component cable will. I use VGA cables on my CRT monitors to display 2 20'' monitors at 1900x1440 each. It may make it look clearer on your HDTV set but it will never look extremely crisp as it is always being stretched to fit that TV. The dreamcast only outputs in 480 so you will never make it higher resolution that that. If it functions anything like my component cable on my ps2 then it will crispen the image on the HDTV. There is a massive difference between composite and component. You could always give it a go and just take the cables back if they dont work. many local electronic stores have HDMI to VGA Cable for very cheap.
A fiber-optic system is similar to the copper wire system that fiber-optics is replacing. The difference is that fiber-optics use light pulses to transmit information down fiber lines instead of using electronic pulses to transmit information down copper lines. Looking at the components in a fiber-optic chain will give a better understanding of how the system works in conjunction with wire based systems.At one end of the system is a transmitter. This is the place of origin for information coming on to fiber-optic lines. The transmitter accepts coded electronic pulse information coming from copper wire. It then processes and translates that information into equivalently coded light pulses.Think of a VGA Cable in terms of very long cardboard roll (from the inside roll of paper towel) that is coated with a mirror on the inside.If you shine a flashlight in one end you can see light come out at the far end - even if it's been bent around a corner.
