ADDITIONAL DETAILS
You will need wire. The perfect wire for this, believe it or not, is ethernet wire. The kind i like the best is the wire with many strings, not one solid wire. The solid wired ones, when they are bent too much, they break really easily.

I made one of these using old ports from 2 videocards, and 2 networkcards. You could use that instead of buying new parts.

---Please procied to step 3 for the Schematics and diagrams---

Step 2: Schematics and Diagrams.

If the first picture is too confusing, use #2.

This is the text base version of it. First number is ethernet pin, and second is the VGA/hd15 pin.

1 - 14
2 - 13
3 - 3
4 - 7
5 - 2
6 - 5,8,10
7 - 4
8 - 6

*NOTICE ethernet pin "6" is indeed connected to all of the following pins - 5, 8, and 10. These are the R, G, B grounds.

Less than a week i received all my parts from Newark. The pictures show what i received.
