My Homebrew Vga Cable!
« Reply #15 on: July 27, 2006, 03:20:00 PM »

Good job on the cable! I used one of my 1881 chips and made one that goes inside the xbox. Still needs some work, since the tutorial i used said i needed switch one, and three. I may have to try one that plugs in aswell (For fun).

@dpbmt: Order the parts in my above post and you will be fine.

EDIT: @devilmaycry666: I like your design, very clean! I'm not personally a fan of major internal modifications myself, but it does look very nice! Although, I imagine all that extra wire is difficult to work with when installing/removing the XBOX motherboard...

or a 680kO resistor.


textbook's diagrams... haha.  They're really based off l33 and some other people's and drawn by me.  He did give me credit though.  Textbook did do a pretty good job of compiling even more of the information out there.  Although i've yet to see his website load where the images don't overlap the text.

You can get most of the parts off ebay for relatively cheap.  I recall buying 100 resistors or so for about $5 shipped.  same for the LM1881 chip.

You can use the RGB Bios patcher http://forums.xbox-s...&...t&p=3430372
which will patch any BIOS for RGB output.  It should fix most SOG problems w/out the SOG chip on your VGA cable.

Hey Frosty, that looks very nice, very clean and well done.  Congratulations.  I did a similar thing by putting my circuit in a box, but if I ever took a picture of it I'd make you guys cry.  It looks pretty bad, but it works perfectly when I want it to.  To be honest, I'm really surprised that a 470k resistor worked for you as well.  I think I'm the first person to have used that value.  I was just too lazy to drive the 10 miles to Radioshack, and I had a 470k already.  Once again, great job, that looks amazing, hope it works great for you.  ClintiePoo used my tutorial and made a nice looking cable as well.  He had a SOG monitor, so he didn't have to build the circuit.  With your permission, could I add your photograph to my tutorial?  I'll give you credit.

By the way, here's ClintiePoo's Male VGA cable for use with a SOG display:

The cable is still working great.  Thanks for the tutorial and help! smile.gif

just a couple of quick Q's before i make mine,
im using this diagram Vga mod for reference-

1. does it matter what way the capacitators are hooked up? have they got a + and - side?
2. on the little circuit with the resistor and capacitator do you connect them together i.e by their legs

im going to try a patched version of the 5035 bios, has/does anyone else use this and does
it work o.k for you?
i got all the bioses that support vga, but i dont know what the best one for my ver. xbox is and
what ones would work???

I believe a patched bios is not enough. At least it wasn´t for me. The best bios seems to be the indbios-vga patched but that won´t force progressive nor sync on green, so many games with no 480p support won´t be visible.

For example lastest Splinter Cell starts proberly, but then he screen goes green.

It seems the best way is to follow the guide and install a softmod (even if you had a modchip) so you can use nkpatcher vga patches.

Btw that tutorial is for a NON-sync-on-green monitor. SoG monitors doesn´t need the IC.
 You better follow this: http://xboxvgatutorial.host.sk/

Honestly the resistance is still a mystery even to me.

I think it all depends on your monitor frequency range, but like I said, I really don't know.  Most people would be best off choosing a 680kohm resistor.  That's why I suggested it, then said it didn't work for me and explained a possible reason why and what did work for me.

My diagrams....are not my diagrams - exactly.  I never claimed they were and I tried to be careful and give everybody credit and link to their tutorials.  About the old website...lol.  I did it in some MS Publisher or whatever it was called that I had.  I had a lot of problems with it ... where images and text would get messed up like you said.  So I just kept adding breaks everywhere until it looked good on my Firefox w/ 1280x1024 resolution.  I recently ported the tutorial over to my website, so all images should load now (and faster) and the formatting should be correct.

People -- please stop linking to the old host.sk tutorial.  Link to the new one on my site (http://www.360mods.n...cle/sid=32.html)

The 360Mods site isn't much now, but I plan on working on it a little more later, and it's a good place for me to host my tutorials without having to worry about editing.

Let me repeat...

Not my diagrams, got them from somebody else
Not my tutorial really...just compiled 5 or 6 of them into one
Use a 680k resistor first, if that doesn't work then try the "lucky guess" 470k
720p will be a purple/dark tint on MOST monitors (Frosty, I'm starting a thread on that btw)

Thanks to the other tutorials I used when I made my cable

What resistor are you using? I use a 470kohm resistor, and it works on every monitor i've tried. If you are using a 680k or a 340k then that is probably your problem.

If I have SOG monitor and I use the extra parts will the signal be messed up or will it display correctly.

The 'extra' parts will not hurt it at all. Infact I recommend using them, so you can use your cable on ANY monitor, instead of just SoG monitors.
