Actually im using the "component/D-SUB" option, so im guessing the cable is doing YPbPr to VGA. It works up to 1080i. I do have an Xbox 360 and im using a VGA cable for that. It did have a slight washed out color problem, but i fixed it with a ArcadeVGA video amp. My main hobbies are building arcades, that actually how i got this idea in the first place. Unfortunately the ArcadeVGA video amp only works if the source has native VGA output. I really just need to know how to read the schematics. But thanks for the link i did learn something new from it.
