You mean $40...

Anyone know what the link means in the diagram?

Also kind of sucks that you probably need to buy an Xbox video cable to rip it apart to make the VGA cable.

I don't understant a jack of cables etc soldering kind of things, so pardon my stupidity. But - what does one need to make a VGA cable by theirselves? Original x360 cable and this kind of adaptor? A normal VGA cable that has wires going to x360?

Can someone expand on this please?

Honestly I looked at them, and said wtf? I think i'm missing somthing... I know how to solder and basic electronics...
Anyway is it really worth shitty construction to save 10$?

Normal Connector=30$
VGA=40$

I found this tutorial (here on X-S of course) showing how a vga adapter could be made for the x-box using an old video card and a x-box audio/video cable.

Obviously the process would differ for the 360 but I think that since the 360 naturally supports vga it should only be easier.

If you have a old video card laying around and you use the cable that comes with the 360 this is a $40 savings.

So cutting up the xbox 360 component cable to make a xbox 360 vga cable saves $40?

You dont exaclty need a cable to convert it, you can always pick up the vga connector and then solder the wires to the leads on the board. Sort of like the mod to install a vga connector like here except you dont need a sync on green monitor or any special circuits for the signal.
Title: Rgb And Vga Pinouts
Post by: OcnewB on November 16, 2005, 04:56:00 AM
So correct me if im wrong. On the left side you see the 360's video output connector which is located in the xbox. On th eright side you see how to connect on scart(rgb) and vga.

So i get an ordinary scart cabke with 21 wires (around 10 dollars) i cut one side off and solder the points to the connection points in the 360?

I dont get it to be honest. Do i need a normal x360 cable which comes with the premium package , and start soldering in the plug that attaches to the x360?

And what happens with the optical audio out?
Title: Rgb And Vga Pinouts
Post by: Arakon on November 16, 2005, 05:16:00 AM
The connector on the right side with the numbers pointing to it is the xbox360 connector.
you could i.e. cut up the cable that comes with it (especially when you are getting a core package since it's only composite then), or a third party composite cable (which will be a good bit cheaper than the VGA/RGB ones).

the optical out on the 360 connector can stay in place just as it is, no modification needed for it to work.

The main focus is european people, since the 360 comes with YUV cables, but most europeans simply don't have HDTV capable TVs, so making a RGB cable from the YUV one is both useful and cheap.

One thing that's missing is the digital out, which would be a pain I'm sure, but is what I'm aiming to use.  Unless of course, that is what mysterious "pin 15" is...?

pin 15 for VGA is the data pin, which tells the monitor which resolution to use.

an optical output is already on the 360 plug, you can just keep using that without any extra work.

Post by: twistedsymphony on November 16, 2005, 08:06:00 AM
Actually wiring this up could be very cheap...

If you get a solder cup Sub D-15 female connector you could wire a VGA port right into the 360.... the above will cost you about 50 cents then it's a mader of soldering it in place. If you want more then one connection simply wire in a switch or two...

Anyone who can't grasp what I'm talking about needs to take a look at Spillage's "All outputs configurable" mod. http://forums.xbox-scene.com/index.php?showtopic=117473

Since i'll be purchasing the premium 360, and not being able to use the component cables for my TV, i was planning on turning it into a vga cable.

My question is, could i not just attach a VGA to RCA 3 Female cable to the 360 component cable:

user posted image
HD15 (VGA) Male to RCA x 3 Female, D / Shield, (HD15 to Component Video) Adaptor, 1 ft


Or will i have problems with the H&V sync?  And if that be true, would having a sync on green monitor solve this?

Also, where are the H&V syncs on a component cable?

If this works, it would be a shit load cheaper (cable adapter is only 5 bucks plus shipping) then turning around and paying $40+ on a 360 vga cable.



Title: Rgb And Vga Pinouts
Post by: Arakon on November 18, 2005, 06:57:00 AM
I doubt that adapter will do YUV to VGA conversion, since VGA uses RGB, and requires seperate sync lines, as well as missing the data pin, etc.
Title: Rgb And Vga Pinouts
Post by: Foe-hammer on November 18, 2005, 05:20:00 PM
Oddly enough, though, this is exactly what i used for the original xbox (execpt it was male, instead of female), with the vga bios, and it worked perfectly.

Since it worked with my original xbox, wouldn't it also most likely work with the 360?
Title: Rgb And Vga Pinouts
Post by: Arakon on November 18, 2005, 05:21:00 PM
the vga bios outputs RGB and sync on green, not YUV.

the outter casing is clipped together.. to fully access the contacts you will have to slightly bend the shielding open, but it'll bend back into shape fine.

Post by: Foe-hammer on November 22, 2005, 04:11:00 AM
For those who are going to do this mod, save yourself a lot of time and frustration by getting a Ohm meter to map out each wire.  With one you will not need to crack the 360's AVIP plug, and you'll know exactly what wires to solder to in the vga plug.

Take it from someone who doesn't have an Ohm meter, and tried half the night with no success.  Good news is i have a 360, bad news is it's just sitting there, because i will not play it tell i can make a vga cable (cannot bring myself to play it on my regular TV in 480i).

I typed too soon/without thinking...

You will definently have to crack open the 360's AVIP case in order to link the two pins together, and solder wires to the H&V sync.



Questions:

1) Is the H&V sync wires present in the component cable (i.e.; can i cut the cable and find the H&V wires there)?

2) How do you crack open the 360's AVIP casing without breaking it?  When you say clipped together, Arakon, how do you unlatch the clips?  I don't know where even to start, besides prying on the joint, and possibly breaking it.

no, since component doesn't use H/V sync.. in fact it only needs 3 video signals + grounds + audio.

yeah, that's the big trick.. there's 2 clips on each side, but since the case is made from hard plastic, they may end up breaking.. try pushing with a wide, flat screwdriver against the small gap between the two halves.. if all fails pry it open by force and either add a drop of glue later or wrap some tape around it after the mod, it'll work fine that way.

I just applied even force downward with the back side of a razor blade, to each side of the AVIP case, and it snapped right open.

Title: Rgb And Vga Pinouts
Post by: Arakon on November 22, 2005, 10:12:00 AM
the more the better, as grounded wires also have a shielding effect and reduce interference.
if you are using seperate wires and don't want to hook up 13 of them, use at least one for each color ground (R, G, cool.gif and use a thicker wire for another ground if you have interferences.
Title: Rgb And Vga Pinouts
Post by: Foe-hammer on November 22, 2005, 08:57:00 PM
Well, i finally finished the vga cable, and it works like a charm.  I had to desolder the wires from the AVIP tah went to the small plug that attaches to the pcb board for it to work.

360 vga conclusion:

I had only 6 resolution options to chose from; 1280 x 1024 was not one of them.

The contrast level was too low, making everything not as vibrant, kind of washed out.  I expected better.

In order to get true blacks, i had to turn down my brightness much lower then normal (35-40 range).

I have been playing with the original xbox on my pc monitor for years now via the vga bios, and also with a transcoder (x2vga).  The contrast level, and color vibrance is better then what i'm getting with the 360 in vga.  I compared halo 1 and 2 side by side.  But this also goes for the only 360 game i tried; PDZ.

I don't know if the ms factory vga cables would produce a better picture; i wired everything correctly, and am not getting any interference, so i'm guessing prob. not.

Post by: CooLJoE on November 23, 2005, 06:40:00 AM
Well, I can tell you that the factory MS VGA cable does have a wide range of resolutions. Honestly, it shouldn't matter whether you wire up the VGA connector yourself or use MS's one. The resolution list in either situation should list alot of possible choices including 1280x1024 (which is what I'm using on my 17" LCD). That or the Xbox360 doesn't detect that your monitor can use that resolution using that VGA wireup.

PD0 has options for display type within the game... I set mine to DLP (because I'm using a DLP display) they might want to try changing that to see if you can get a better picture out of it.  beerchug.gif

Post by: Foe-hammer on November 23, 2005, 06:35:00 PM
1280 x 1024 res was not included in the US 360's.  I had to connect to live, and it updated my 360 for 1280x1024 res support.

Ya, i noticed the different TV options for picture quality in PDZ, all it really does is adjust the brightness setting in the game, so either way the best i can get it to look is on 6 brightness level.

Things are looking better on my 360 via vga cable and pc monitor.  With the added 2xAA to halo 1 & 2 emulation, in the latest live patch, the two games look much better then when i first viewed them on the 360.

Colors and overall picture quality looks good now, but there still is not enough contrast to brighten up my display (i have my contrast level maxed out at 100).  Increasing the brightness setting just washes out the picture.  Not enough contrast seems to plaque all CRT pc monitors, although i never had this problem when playing pc games, or xbox games via a transcoder (x2vga).  

I'm tempted to buy the VD-Z3 transcoder, as it accepts any component cable input.  Maybe it would produce a more vibrant picture for the 360 on my crt monitor.

That's interesting.. does the resolution option remain even after you unplug the HD and boot the box up? that would confirm that the dash/bios is indeed updatable through live.

btw, it could also be that your monitor dislikes the 360 signal some, have you had a chance to try the cable on another monitor?

Yes, the updated 1280x1024 res remains (and shows up in the dash as a res option) when booted up, with no hdd present.

I have not, but will some time.  I'm thinking opening my monitor, and tweaking the brightness and contrast defaults to compensate for the 360.  Hopefully that will help.

I tried this out, and I think it's great! smile.gif  But my brightness is really low, if I max the brightness on my monitor it looks almost normal.  The strange thing is when it first boots up the brightness is perfect for about 1 second and then turns dark.  I was wondering if anyone knows what's happening?  Thanks!

Post by: frobnitzz on December 13, 2005, 09:32:00 AM
I'm making my own at the moment from the standard composite cable.

I ripped the 360 end apart so I was just left with the black plug, then commenced wiring. I've not soldered the connections, but wrapped each wire round its corresponding pin - should do the job right?

I checked the connections with a multimeter to ensure that the pins inside the 360 and match up with the vga end and they do. Checked I had no shorts (except for ground and pins 20-21 of course) then glooped hot glue gun over it all to keep it all in place.

Plugged it in last night but it didn't work, just got a red flashing light on the xbox - which presumable means to cable is connected. Wasn't in very tight and I'm wondering if it's even in enough...

I've one theory as to why it didn't work - that being the outer casing on the 360 end isn't there anymore, I didn't put it back on... I'm guessing it needs to be put back on and connected to ground in order for the 360 to pick the cable up? I get this because looking at the 360 itself there are metal tabs round the inside of the port.

I'll post a pic of my ghetto creation later.

I'd just buy a cable if I could find one! (not paying ebay prices!)

Funny - not - thing is I've got no other cable so can't play on my 360 at the mo!
Title: Rgb And Vga Pinouts
Post by: chopps on December 21, 2005, 06:51:00 AM
Frobnitzz,

I don't believe the xbox needs to have the outer ground in order to boot.

I made a similar modification to my composite lead, and wired it to an existing RGB Scart cable I had spare.

Before I fully reaseembled it, I tried it with just the 360 plastic connector without fitting the metal shields, and it booted and played fine.

I would highly recommend that you solder the connector on, though the pins are very close together so take your time and get some desolder braid before you start.
Title: Rgb And Vga Pinouts
Post by: Arakon on December 21, 2005, 07:34:00 AM
the black part actually goes in very deep into the 360 connector, it takes some force to get it in all the way if the rest of the casing is missing.. and even more to get it back out, you'd likely rip the wires off again.
you're best off putting the casing back around it, at the very least the metal one.

REALLY old bump

but I thought this was a useful topic, came across it in the search a few dyas ago

motivated me to do the mod myself cause i didnt wanna spend the 40 bucks on a vga cable when i knew i could  do it myself.

well, here goes: (yes, the pics are really crappy, my webcam has to hold me over till my new camera arrives)

(IMG:http://img.photobucket.com/albums/v285/g0t_m4xx_21/Dev/Picture18.jpg)

(IMG:http://img.photobucket.com/albums/v285/g0t_m4xx_21/Dev/Picture17.jpg)

Each signal on the VGA port is twisted around its respective ground, to reduce interferance, and I used some actual audio coax cable to hook up the audio to the jack i installed. As you can probably see, I didn't rip apart the metal shield on the AVIP, i just ran the wires under the motherboard and soldered them to the pins down there (they're convienently numbered the same as in Speedy22's Xbox 360 headers and connectors document: dwl.xbox-scene.com/tutorial/Xbox_360-HandC-V1_4.pdf )

As for the wire that must be grounded to enable VGA mode, I found an unused pin on the VGA plug that is tied to ground inside my monitor or something, so when there's nothing connected to the VGA port the 360 functions normally based on what's connected into the AVIP, but as soon as a VGA cable is plugged in it goes into VGA mode.

the overall result was very good, looks amazing at 1280x1024
