Story:
I ordered and tomorow will be recieving a new 19" LCD Monitor which will be replacing my current 19" CRT Monitor. I wish to use the CRT Monitor as a display for my Samsung DVD Home Theater System. The system has both progressive scan component output and composite video output but i would prefer to use the progressive scan component output.

VGA port i plan to use:

I opened a VGA to DVI converter i had and will be trying to seperate them. What is the white/clear material surrounding the center? It feels kinda like soap but it doesnt flake like soap does. its also not elastic so it cant be hot glue. maybe just a plastic? i would like to know so i can remove it accordingly

Most everyone has seen one of these:

Thats the cable i want to cut and get one side to be the VGA

I found this Image of the VGA pinout:


but im unsure how i would wire it together.

Any help is greatly appreciated.

if im not mistaked you need to design a circuit or get a box that will actually CONVERT the component signal to the VGA signal... you cant just wire the component wires into the VGA connector and expect it to work on a pc monitor.  

Some cables DO just send a component signal into a VGA adapter.. but those are for projectors that CAN accept component signals like that.  your pc monitor wont be able to.

ive seen those boxes and i even own one but to be honest the video is really crappy, not being able to read font etc...

building a circuit would be a new thing for me, but if thats what it takes im eager to learn. any idea what the circuit would look like?

Ken Gasper's circuit he used to make his boxes.  Have fun.

as i said im new to the circuit building im sure i can google what all the symbols mean and decipher the plans but could someone tell me which pdf im going to be doing? thanks

Take the time to look through some of the threads here and maybe in other forums as well if you want. You'll find that most people either make a homebrew vga-cable or buy an expensive transcoder. If you have no problem with soldering, do the homebrew cable.
In fact, you can solder the wires of a component output to a vga-plug. You might even use a simple adaptor. But if your monitor doesn't recognize composite sync on green, like most non-tv-monitors, you need to build a sync-seperator-curcuit which substracts the sync for standard vga. But there is one other problem you will face: you probably need to use a kernelpatcher or vga-bios because the output is YUV, not RGB.

All of them.

Note, that the XboxVGA.pdf is the "main" schematic.

There are two separate circuits inside the XboxVGA circuit.  Those boxes that are labelled LM1881 and MAX4383 need to be wired up.

That's what the other circuits are for.

Instead of including the LM1881 and MAX4383 schematics, he decided to show them individually so it wouldn't be a big mess of a schematic.

I would suggest building the LM1881 and MAX4383 circuits first, then proceed to the "main" circuit.

Or just buy a transcoder.

oh ok, so pretty much this isnt a project to be undertaken by someone new to circuit building.

one last question:

are s-video, composite and component all as difficult to wire to vga?
