Which laptops from the XPS range have hdmi as standard?

[Conrad11]

Hi there,

Does anyone know for sure which laptops from the Dell XPS range have HDMI out?

And is it a "base" thing, because you can build different spec machines, i am wondering if it's on all the machines in that range.

I have been told the HDMI out is on all of the XPS M1330 & M1530 range but not the XPS M1730, is that true?

Thanks.
