MP4 Slides show will not loop

[Joliet_Tech]

I have a power point slide show that I would like to play from a USB drive on my Samsung monitor (Model: UN55H6203AF).  I converted the PowerPoint show to a mp4 and put it on a USB drive and it plays fine on my PC.  However, when I play it on my monitor, it does not loop - stops after one loop.

Any help would be appreciated.
