After reviewing the user's manual (zero info) and reviewing other posts I finally figured out how to advance slides on the projector using the remote. However this only works off a USB connection not off an HDMI to HDMI (my laptop does not have a VGA slot so I cannot use the connection cable that came with the M110).  Does anyone else have the same problem?  Or am I missing something?  I can run slides off a flash drive this way but not off the laptop.
