Which adapter for DVI to Component

[RVZ]

I'm trying to use component on my tv, but the adapters I have doesn't seem to work.  I've tried using a DVI to Component, and S-Video to Component.  The DVI one doesn't work at all, I'm just getting garbage.  The s-video one also doesn't work, although I can see Windows running on it, but it's showing a plit screen, and very fuzzy.

I've tried using different cards as well, Radeon X1300, Geforce 8500GT, Geforce 6200LE & Radeon 4650.  Am I doing something wrong, or maybe using the wrong adapters?

What TV are you using?  It sounds like your PC outputs 480p and above, but your TV can only handle 480i.

It's a Samsung 29", will have to check the model number.  I've now managed to get a clear output using soft-15k, but with the svideo one, it's black and white, and with the dvi one, it's all blue.  Any idea what may be causing that?

The "S-Video" one is actually not S-Video at all.  It's real component on a connector that is just physically similar to S-Video.  Note all the extra pins.  Unfortunately, AMD and nVidia both used the same connector but with different pinouts (D'oh!).  Make sure you've got the right dongle for your card.  It may also just be that you need to enable the component mode output in the driver - it may be defaulting to S-Video and re-using the luma pin, which would explain the lack of color.  This is your best bet for making things work.  You shouldn't need soft15k for this - the drivers should have a "480i" option.

The DVI one uses the analog output on the DVI connector (DVI-I) with sync-on-luma, but it's up to the PC to output YPbPr component instead of the more normal RGB.  I don't know of any devices that do this without serious driver hackery, but maybe some exist?  I know some old ATI cards (9000 series era) could be convinced to do it with the right EDID data on a special dongle that used to be more popular than it is now (nothing supports it anymore).  Those cables like you picture are normally intended for use on projector inputs that accept either color space over the same set of connectors (often there's an option in the menu to pick).  Getting a "really blue" but otherwise good picture is a dead ringer that you're applying video at the right resolution but in the RGB colorspace to an input that expects YPbPr.

Thanks for the reply.  How do I enable the component mode output in the driver?
