PowerPoint for WP8

Hey guys. Just wanted to check in on something. I'm looking into getting an HTC 8X or a Lumia 920, and I was wondering: can I take a PPT presentation I (or someone else) made in the desktop version of PPT and use a WP8 device to present it, via a VGA or HDMI adapter cable, or something like that?

I was looking here and it doesn't seem to mention it, but I just thought I'd check with the Tribe in case you guys have something up your sleeve I don't know about.

Thanks!
