nVidia 8500 GT Component Output through DVI port?

I have a GeForce 8500 GT with my HP Pavilion d4996t, but it only came with an S-video port (no dongle or HDTV port), along with HDMI & DVI. Can I get component output out of this? I've seen cables that are DVI-I to Component, but they all say "the video source must output component video signal through the DVI port". So does this card output a component signal through the DVI port?

Thanks in advance!

The chip has the capabilithy but not all the manufacturers that make cards using the chip support HDTV-Out(component). My Gigabyte 8550GT does using a dongle on the 9-pin din connector. The DVI-port on my card supports a VGA dongle.

If your card did not come with a dongle and your system documentation does not discuss one then the odds are thay your card does not have the support.

All 8500 GTs come with a 7 pin mini-DIN ( just like all 6600 GTs (9 pin)*, all PCI-E GF7 and some AGP GF7 (exception AGP 7800 GS) and all GF8 series cards). This allows a standard 4 pin S-Video cable to plugged in. It also allows the 9 pin nVidia mini-DIN adapter to be plugged in to provide composite, and component outputs to be enabled from the port.

You need one of these:

Check that the so called 'S-Video' port in fact has 7 pins.

Walford, all DVI-I ports ( which all PC graphics cards known to man come with ) in fact have an analogue VGA output and a DVI-D output in the same connector. A DVI to VGA adapter simply extracts the connections for the VGA output in the DVI-I port and presents it in a VGA form factor for connection to a VGA connection.

* Not all these cards actually come with the required adapter/cable. That does not mean that the card does not come with the connection. For instance there is a common misconception that some 6600 GTs didn't support component through the 9 pin mini-DIN. This simply isn't true, they all do but they don't all come with the necessary adapters to keep the cost of the card down.

I am aware that a DVI-I port can support analog output in addition to the DVI-D output. However the cards from different manufacturers us this feature in different ways. Some cards use the analog pins for VGA, and some cards use the analogy pins for YPrPb component.

And many cards although the have DVI-I connectors do not support any analog output at all but they don't want to block the spade end pins since many DVI cables require that the pins not be blocked.

Unfortunately, I bought the dongle separately and it wouldn't fit. Only an s-video connection fits. It's ok - a friend has another 8500GT lying aroung that has the correct connection.
