Yes it is possible. I use FatShark Dominators with mine.
1) Acquire Phantom 3 Standard and FPV Goggles with HDMI in.
2) Apple users need a lightning to HDMI adapter (This works much better with iPhone 6 vs. iPad)
3) Connect Goggles to your devices mini-HDMI port.
4) Make sure Goggles are in I/O mode. In my case FatShark's, switch the transmitter/IO button to I/O
5)Power up your controller, your tablet/smartphone (I had to use my iPhone, not my iPad due to border issues) and the P3S
6)Attach FatShark Goggles to their battery
7)On the FatShark, to get the best view, I use HDMI 2D
