Title: Will a component-to-VGA transcoder remove sync on green? I'm getting a green...
Post by: sofakng on January 11, 2008, 03:10:39 PM
I just built a sync seperate so I can use RGB from my Playstation 2 on my monitor which does NOT support sync on green.

The picture displays fine but it has a horrible green tint...

I have two questions:

1) Can I remove this tint somehow?

2) The Playstation 2 uses sync-on-green.  If I use PS2 component cables and a component-to-VGA transcoder (eg. X2VGA2) will that remove the sync on green or will I still have the problem?

Thanks!

A component to VGA transcoder should remove sync on Y ("green"), but it will output nonsense since it expects component video on the input. You could transcode the RGsB to YPbPr before hand but that would be just absurd.

You only want to remove the bottom 0.3V of the signal which is sync. I think this can be done by DC biasing/clamping ONLY the video, and using a series diode to remove the sync's negative voltage. I'm not terribly good at analog or I'd try to design something for you, better leave it to the other guys.
