DIY - Xbox360 to VGA Adapter

Introduction: DIY - Xbox360 to VGA Adapter

The idea came from a need from a college friend in need of video games on the cheap.

This is a very in-expensive project, mine was free because In had the parts sitting around.
You most likely do to. 

Allows a computer screen to be used as an HD TV for Xbox 360's.

List of Materials:
     -Computer Screen
     -VGA Cable (25 pin blue connector for computer screens)
     -Female Component Plugin (You can use a Female RCA, but this is more confusing as the colors do not match up.)
     -Soldering Iron (Recommended)
     -Sound System (If you want sound.)

     -Basic Soldering Skills
     -Need For An HD TV
     -Multi-meter or similar device
     -Hot Glue and Glue Gun

Step 1: Step One - Cut VGA Cable

This step is for the VGA Cable.

Cut the cable down to the size you want.
Make sure to have the connector to the computer screen still attached.

An acceptable length is 3 feet. More still works and may be more suitable for your needs.

Step 2: Strip the VGA Cable

This is one of the more difficult steps, but it is quite easy.

Strip about Two inches off.

Take a pair of scissors and carefully cut the outer plastic away.
The easiest way is to place the open scissors on the part you need.
Squeeze firmly and circle the cable.
Finally pull the plastic off.

First thing you'll notice is the metal shielding.
For this you do not need it. Pull it away from the wires and clip it off.

Step 3: Strip the Inner Wires

I emphasize this now. BE CAREFUL.
You do not want to cut through the wires.
Mostly so its more convenient.

As you may see there are numerous wires.
Your goal is to find six of them.
Luckily these tend to look quite different.
In my case these ones had grounding foil around them.
Since these tend to be the ones you're looking for start here.

When you strip these wires the first thing you should notice is there is possibly grounding foil surrounding an insulated wire.
Pull the foil to the side for later use.
This is the ground for the inner wire and is 100% needed.

Something you should notice you should notice is there are four wires that look different.
Another thing you should notice is the color of the inner wire. Three of the four should be colored: Red, Green, and Blue.
These are the three you want.

Next strip the inner wire.

Repeat this step for all three of these wires.

Step 4: Test the Wires

The idea here is to test the wires to find out where they connect.

Test the wires using a multi-meter set to resistance.

The three inside wires should connect to pin 1, 2, and 3 on the connector.
The three outside wires should connect to pins 6, 7, and 8 on the connector.

If they do not these are the wrong wires.
If they do skip the next step.

Step 5: Four Continued

If step four worked properly then skip this step.

This is the problem solving step for step four.

Strip all the wires and test them until you find the wires that match up to pins 1, 2, 3, 6, 7, and 8.
Then move on.

Step 6: Soldering Time

Pretty much here is when you solder the connections together.

Pin One goes to Red Inside.
Pin Six goes to Red Outside.

Pin Two goes to Green Inside.
Pin Seven goes to Green Outside.

Pin Three goes to Blue Inside.
Pin Eight goes to Blue Outside.

Step 7: Stabilizing

This is where you hook it up to the computer and stabilize it.

The problem being is since not all the wires are hooked up the screen flashes black and should have a green tint.

To fix this click the menu button on the screen.(Note: The screen has to have an image to access the menu. Hit the center button on your Xbox controller as this tends to keep it stable long enough.)
 -Look through the options(This is usually in the advance settings menu.) until you find the setting to switch between RGB to YPrPb.
     change this to YPrBr.
 -This should stabilize the colors.
      If not contact me and I'll help you. 
 - Feel Free to adjust the color and brightness to better suit your preferences.

    I have made it and get to the green tinted screen, my monitor doesn't have a YPrPb input colour format option, so I would like to know how one would go about doing so.

    i know this is an old post but any help would be great

    Can you make RCA Video To VGA Converter


    6 years ago on Introduction

    Cheers. I've also got green pic on my LCD and does not have an option to change to YPrPb on my LCD. The solution, probably, would be to connect Vsync and Hsync but the problem is that my connector doesn't have these pins! I have an original xbox AV cable. Anyone else having such a AV cable?

    Maybe I can try to pick the vsync and hsync directly from xbox (mobo?)? Would appreciate any help.

    hey i know this post is a bit old but i had the same problem. Apparently, the later models of the av cables don't have all the pins, only the ones necessary for component output. I had the same problem, but i found a diagram of the pinout, and with vga, there are some pins you don't need (like many of the ground pins and the optical audio.) If you're careful, you can pull the pins out of the connector with a needle-nose pliers and re-insert them into the correct spots. I had to put pins in the h-sync and v-sync spots. All of your grounds can go to one ground pin, just to save pins, and in fact, I had trouble getting the red to come through at all until i put its ground in with the rest. Pretty much all you need for vga is the red, green, and blue, and hsync and vsync, and a ground. (And left and right audio.) All the grounds can, (and really should for simplicity's sake) go to one ground pin. Alternatively, you can hunt for an older av cable that does have all the pins in it.

    I've soldered hsync(pin 11), vsync(pin 12) and ground (pin 2) on motherboard and still get green screen after connecting to LCD. so I thnik it's time to give up - don't want to damage my console.

    I would quit whilst you are ahead. I would help out on this, but I'm more into the coding side of things and have little idea how this works. As I have no idea what the hsync and vsync pins do. Sorry, I really would like to have helped.

    To show you better I attach two pictures where you can cleary see "blank" pins.

    My idea is to take RGB directly from original RCA (as on photo) - and it's done. I will take audio also from RCA's. Now where to take the Vsync and Hsync from if I do not have them on my connector?

    hi , i have a digital tv box that i want to connect on my vga monitor , i made this cable ,screen tint green like you say , but in my tv box settings there is not any rgb and YPrPb option , only 1 option that set to yprpb . what should i do ?:(

    i soldering GND wires together and connect them to pin 5 in vga side , is there any problem ? or must connect them seperate ?

    sorry about bad english :D

    I will do my best to find you a solution, the only delay I may have is if I can't find a similar computer, I'm on a tight budget, why I made the cable, so it may take me a little while, I'll see if I can get a variety of computer screens and cables for an update.


    6 years ago on Introduction

    I will likely update, I now have access to better cameras and staging areas.

    I have a problem. The green ground pin doesn't connect to anything? I wired up all 3 of the rgb grounds into pin 8 on the ps2 ground. Red and blue read a resistance value but my volt meter reads 0 ohms from pin 7 (green ground) to the un-insulated wire that was foiled together with the green insulated wire. The weird thing is the green ground is wired with red and blue ground but it still doesnt read anything on my meter? That should be the ground and it is not. I have tried 4 cables btw. What is the green ground wire? Also whats with the foil, you never explained why we needed to keep it.

    It's been a while and I may do an update on this, haven't done much in the way of photography but, shall not be hard. As well I have a few things to add to make this project easier and more effective.

    nice! Although i was hoping you could change RGB to YPrPb on xbox itself, now i have a pretty green (test)screen. This availability of a switch between RGB to YPrPb is damn important haha, thx anyway!
