Your graphics card has S-VIDEO output, and your 7" LCD has only an AV input, right?
You need an S-VIDEO to RCA (also known as Composite) cable:
The S-VIDEO end plugs into your graphics card, and the RCA / Composite end plugs into your LCD monitor. You can get both 4-pin and 8-pin S-VIDEO versions.
I'm still confused though...

...Is this a wire that came with your DVD player, and you're asking if you can use this wire to hook your PC up to the 7" LCD?
If so, then the answer is no, because the cable you described (S-VIDEO like cable with a headphone jack and power like plug, which might actually be RCA) sounds like an adapted cable for use with specifically connecting the DVD player & LCD together.
