I purchased a Nebular MARS II projector hoping to show the video from my PP4 v2. Turns out it will not read DJI's MP4 format. The format has been accepted by every medium i have used. I can get around problem using Power Director Software(would imagine any video software would work) just input then output and this works using a the USB port on the projector. The people at Nebular were just unhelpful, so am returning it to Amazon.
