PS2 VGA cable, splitting sync on green

[Cyberghost]

I guess this could count as hardware development?

I'm trying to build a ps2 vga cable to use with ps2 linux. Simple, but I want to split the vsync and hsync from green to be able to use any vga monitor rather than struggling to find one of the few that support sync on green. I bought the LM1881 to do this and am using these http://skygate.bravehost.com/PS2_VGA_cable.html instructions to build it. I have a question though, in these instructions, there's no explanation about the green vga signal; green goes in, vsync and hsync come out, but what about green? Shouldn't it also come out somewhere? Does the green signal from the ps2 pass straight through to vga as well as into the LM1881?

Any help appreciated, Thanks!

If your PS2 motherboard is older than GH-015 you can hardmod it to generate VESA standard RGB (VGA compatible) by disabling SoG output (a jumper toggles it on and off in the motherboard) then tapping the sync signals straight from the GS chip.

Not too sure it'd be the best idea to mod it considering it's a DTL-H10000. Unless I can fit the sync signal pins into the av port... Can I? Maybe use the ground pins or the svideo pins...

Also I went to RadioShack to get the resistors and capacitor but they only had 560k ohm resistors. I found the caps but wanted to be sure they were the right ones; I took a picture as seen below:

Ill add picture later because I'm on a shitty iPhone

It starts out by saying to hook up the red, green and blue. The LM1881 is also connected to green.

okthat mostly answers the question but is it even possible IE sync striping on newer PS2s?
or is it easier to get one of these http://www.jammaboards.com/store/cga...-gbs-8220.html
and a scart cable cut the scart end off and wire the RGB lines and sync lines to RGB inputs on the VGA converter?

That has the additional benefit of some scaling. You won't be limited to only 480p games as normal VGA monitors alone often are.
