Hi guys! Long time reader... not that much of a poster...

I have an xbox 360 premium, the one that came with the HD cable with component and composite cables. Recently, I bought a 20' monitor, but where I live, the official VGA AV cable is way to expensive and hard to find, so I tried something that performed very well with a projector.

I got this adapter

Like I said, I have tried this before with a projection Tv, and it worked perfectly.
The problem here is, the screen looks all green like this

(w00t greeniberty city!)

I know it's not the console nor the xbox cable, because when I plug it with component cable in my TV it works fine. My problem is that I don't know if it's that the adapter is not working correctly, or if it can't work because of a compatibility issue between analog->digital signal....

Also,
*When I disconnect the red and blue ends of the cable with the VGA adapter, I can still see the image, but if I unplug the green end and either of the red and blue or both are connected, I don't see anything.

Anyone have some suggestions? What could be the problem? Would this be possible?

Thanks for reading.

It sounds like it's either the monitor or the adapter... Does the monitor do that with a compute/anything else attached?

**Sadranyc** · 08-01-2008, 04:14 PM

Nope, the monitor works fine with the computer, I'm using it right now in fact. I'm not sure if it would be possible to get the image to show correctly, because if I'm not wrong it's going from analog to digital?

**Chrono6456** · 08-01-2008, 04:17 PM

Im pretty sure component cant just be converted to a vga signal so easily, i dunno how it worked for the projection tv though.. I would suggest just getting a cheap cable off ebay.

Thanks for the link. I will be considering purchasing this cable, but I don't want to give up yet, I want to know why it doesn't work hehe... any more suggestions?

**GW2** · 08-01-2008, 05:54 PM

seems like only the green color is hooking up properly. or should i say looks like... but ya, try wiggling the cable around a bit (not to hard. you dont want to break it now!) if that doesnt work then the cable may just not fit into the adapter properly for osme reason OR maybe the adapter is incompatible with HDCP or something?

**Sadranyc** · 08-01-2008, 08:51 PM

That's exactly what I want to know... If it's compatible or not

**BinoPanda** · 08-02-2008, 09:07 AM

I think i've domething like this before, my friend had his 360 hooked up to his HD tv and it was on SD so I switched it to HD and every thing was green, i fixed it by going into the xbox settings and trying every video mode and played with the video settings until it worked, I'm not sure if that will work for you but you should try it before buying something else.

**Sadranyc** · 08-02-2008, 10:09 AM

But what could I change besides video modes (480p, 720p, 1080i, 1080p)? I don't know what else to try... are you sure about this?

**yolarry** · 08-02-2008, 01:12 PM

your 360 post to automatically change those settings. I would ether just try 480p or 720p.

**Sadranyc** · 08-02-2008, 11:12 PM

None of those worked, I've tried already... still getting that green layer.

**p0p5ux** · 08-02-2008, 11:33 PM

In RGB, your missing R and B.
I say buy another cable. Or at least try...

**FreePlay** · 08-03-2008, 07:12 AM

He's not missing anything; it's just a bad adaptor, or a weird monitor.

**Sadranyc** · 08-04-2008, 08:21 AM

I think I discovered the problem, I leave this quote from Wikipedia in case anyone tries the same thing:

"RGB requires an additional signal for synchronizing the video display. Several methods are used:

* composite sync, where the horizontal and vertical signals are mixed together on a separate wire (the S in RGBS)
* separate sync, where the horizontal and vertical are each on their own wire (the H and V in RGBHV)
* sync on green, where a composite sync signal is overlaid on the green wire (SoG or RGsB).

Composite sync is common in the European SCART connection scheme (using pin 17 [gnd] and 19 [out] or 20 [in]). Sometimes a full composite video signal may also serve as the sync signal, though often computer monitors will be unable to handle the extra video data. A full composite sync video signal requires four wires – red, green, blue, sync. If separate cables are used, the sync cable is usually colored white (or yellow, as is the standard for composite video).

Separate sync is most common with VGA, used worldwide for analog computer monitors. This is sometimes known as RGBHV, as the horizontal and vertical synchronization pulses are sent in separate channels. This mode requires five conductors. If separate cables are used, the sync lines are usually yellow (H) and white (V)[1], or yellow (H) and black (V), or gray (H) and black (V).[2]

Sync on Green (SoG) is the least common, and while some VGA monitors support it, most do not. Sony is a big proponent of SoG, and most of their monitors (and their PlayStation 2 video game console) use it. Like devices that use composite video or S-video, SoG devices require additional circuitry to remove the sync signal from the green line. A monitor that is not equipped to handle SoG will display an image with an extreme green tint, if any image at all, when given a SoG input."
