This is one experience of using Samsung smartphone / tablet to run presentations via a projector.
To connect your Samsung Note 10.1 2014 or Galaxy S4 to a VGA to use to
Cable Matters MHL 2.0 to HDMI Adapter (£11) (supposed to work by phone power alone - but did not. But as this would exhauust battery after a while I happily used the USB power connector - this worked fine. I plugged it into a portable back up battery: I used this: **Skyrocket 12000mah Charger Power Bank or Apple** but any USB power source would do)
LINDY Micro HDMI Female to HDMI Male Adapter (£9) - this is needed to fit the HDMI-VGA converter
Out of the box it works fine - immediately recognised when paired with smart phone. The box has an iPazzPort leaflet inside - so I assume that Rii = iPazz. Odd that the Rii has better reviews than one marketed as Ipazzport. No CD in box - reason for the 3 stars - otherwise it works fine.
