NVIDIA 260 GTX: what adapter do i use to get an hdmi port?

Question

What adapter do I use for the first port from the left to get HDMI out? I didn't get one with my Dell 8100 XPS computer.

UPDATE
I don't think it's an S-video output according to this spec sheet: http://www.nvidia.com/object/product_geforce_gtx_260_us.html

Answer 1

They make a DVI to HDMI cord (That one is was under 3 USD).

Answer 2

Its S-Video, DVI and DVI - you generally can trivially convert DVI to HDMI. I don't think S-Video to HDMI converters are common, and s-video is generally lower resolution anyway, and analogue, so such a converter, should it exist, might be expensive
