Is it possible for me to connect an ASUS VIVO Tab RT to a projector to deliver power point presentations?

According to the specs ( http://www.asus.com/vivo/en/vivoTab.htm) , the ASUS VIVO Tab RT does has a micro HDMI plug.

So yes, with the appropriate cables and converters (if needed) you should be able to use the ASUS VIVO Tab RT to display video/Powerpoint with a projector.
