VGA adapter/wiring

[dubloe7]

I'm soldering a VGA cable to the bottom of the motherboard. I used a multimeter to test which cables corresponded to which pin on the VGA cable, and I went to get a VGA adapter for the 360 so I could test which pins corresponded to which solder points on the motherboard, however every electronics/gaming store in the area is sold out of or doesn't sell the VGA adapter. I tried googling, but found only incomplete diagrams.

Also, outside of the mylar shield there was not only an aluminum braided wire shield, but a bare copper wire running along the outside, it didn't test continuous to anything on the connector, but when I solder it should I solder it to ground or something?

I would suggest if you have an extra set of av cables for your xbox using that instead and build a vga cable that just plugs into the av socket. I did it and it works just fine. Plus there are a bunch of pinouts to help with it in the net. But if you need any guidance I'm here.

The reason I'm doing it this way is multi-purpose:
1. it leaves the port itself free for use, perfect since VGA is splittable.
2. it saves space so there isn't a giant adapter sticking out of the back and looping back in.

Also, I don't have spare cables laying around.

Just used the search button, maybe this will help.

Well in that case, desolder a vga port from an old graphics card or motherboard not in use, that you have no further plans on using.

madhaxer, thanks, thats kind of what I saw before, but what do I do with all the other wires from the vga cable?

All the ones with black dots are ground, the important ones are the color coded wires.

So, should I solder all the grounds together to the same pin, or split them up one by one?

Also, do I solder the braided wire shield or the copper wire that runs with it to ground or anything?

You really should dedicate a seperate ground for each video wire soldered to shield it from any interference. The braided ground should be grounded as well. Mine is on soldered as such as well.

I was planning on doing a separate ground for each of the video cable shielding wires, but that still leaves like half a dozen unaccounted for wires, do I just bunch those all together?

And I thought the braided ground should be grounded, I was just thrown off by the fact that it wasn't grounded in the cable itself.

Can you take a shot of the wires in your vga cable?

Scratch that cut them off. Cause the more I think about it the more I remember that those others aren't used.

There are 6 grounds that don't have to be soldered if I remember correctly from one 1 did.
