I am trying to make a hacked VGA Cable so I can plug my Arcade Monitor into my PC.
I cut the end off of a Gateway Monitor and here are the color of the wires I have:
Red
Green
Blue
Grey
Orange
White
Black
Brown
Yellow
Which ones do I actually need to use (Besides R,G,B)???
I understand that I need R,G,B,ground,and H/V sync. But I have no idea what colors are what here.
The Red,Blue, and Grey wires are thicker than all of the other wires, not sure why or what that means.
Please help this newbie ???

I made this mistake once. Just get the part of the wire you have cut off (the one with the connector) and map out the colors to the pin numbers on the connector, and compare with VGA connector pinout diagram. Then you'll know what color is what.
-
Thanks for the help, but I am kind of confused as to what you are saying. I didn't cut off the actual connector. I have the 15-pin connector still attatched at the end.
I did how ever cut the cable again and tried to cut it as even as possible so I could line up the wires nicely to compare to a Pin out diagram. However doing this the wire's are kind of smushed together so it is hard to tell what wire belongs in each row.
That and there are only 9 wires, which doesn't match with the 15 pins.
-
Is it safe to cut a VGA cable and splice it back together? I always heard it was very difficult to get the cable perfectly aligned again so it would work well. Like, if one of the wires is just a tad shorter - the cable will be out of sync.

Here is a link to two pics I took of the cable.
Link Removed
The Normal View pic is the end of the cable. The Reverse Pic is a piece that I cut off and I pulled the wires out a little bit so you can see the colors better. The wires are than in reverse order as far as left and right are concerned.
The colors from right to left(Normal View Pic) are:
Red, Green, Blue, Orange, Black, White, Grey, Brown, Yellow.
It is hard to say what pins are what because everything is kind of smashed together. So I can't tell what row and order each wire is to match it up with the correct Pin. It also looks like the Red, Blue, and Grey Wires has two sets of wires for each. They are thicker wires, so I don't know which one of the two wires I would actually use.
And in the pics you can see there are some what looks like dummy wires. They are actually white strings that are smashed in there too.
I am trying yo figure out the what Pin matches up with each row and color:
Row 1 - Color Order from left to right
Row 2 - Color Order from left to right
Row 3 - Color Order from left to right
This is the order it looks like to me:
Row 1 - Red, Green, Blue, Orange
Row 2 - Black, White, Grey
Row 2 - Brown, Yellow
I hope these Pics say a thousand words and help out ???

My recommendation is to use a multimeter on continuity and map the "wire ends" back to the "connector pins" in order to properly determine "which wire is which".
Trying to line up individual wires based on position in a twisting tube is problematic at best.
Cheers.

I guess it really wouldn't be very accurate trying to line the wires up and take a guess at it.

That website explains a way to test the wires, but it didn't make much sense to me. I didn't quite understand how they tested the wires.
-
They just built their own continuity tester ... if you touch a pin and a "wire" with the ends of the tester ad the lightbulb lights up, then the ciruit is closed and you know that the "wire" end matches the "pin" end.

So this would basically do the same thing that a multimeter would do, just the homemade ghetto way?? :applaud:
