Q1. A black screen on Samsung TV when watching MP4 movies

I have a problem with only one of my MP4 movies. It plays in VLC, WMP, Plex app on RT and Android, nothing but a black screen through the Plex app on my Samsung TV. I can also play it through the AllShare app on the set too.

Q2. Why MP4 cannot be supported by Samsung TV?

I want to watch films in .mp4 format, it shows me the films on the menu screen on the Samsung TV, but when I try to play it says unsupported file.

Q3. Phantom 3 processional 4K MP4 Playback on Samsung 4K TV?

I just bought the Phantom 3 professional and have really been enjoying it but can't play back on my Samsung 55 inch curved 4K TV for my family to view. I tried to record in 4K MP4 and use usb 2.0 with no luck. Anyway there is no USB 3.0 which is disappointing, only 2.0. Any suggestions or insight would be greatly appreciated.

Part Two. Why Can't Samsung LED/LCD/4K/3D TV Play MP4?

You have probably tried a variety of methods at some time. But strangely, althrough MP4 is listed as Samsung TV supported video format, why some MP4 video files work and some just don't seem to be playable on Samsung TV? Your guesses are right! MP4 is a container format which contains various kinds of video/audio codecs, subtitles and still images. It's refusing to play MP4 video file because of the unsupported video or audio codec in MP4 file. Samsung TV only supports playing MP4 format in H.264/MPEG-4 AVC video codec and AAC audio codec. Samsung 4K TV also supports H.265 and VP9 codec.

In addition, the following reasons may also cause MP4 cannot be played on Samsung TV:

  • Some Samsung TV are also affected by MP4 video resolution, frame rate, bitrates and etc.
  • Some USB/digital camera devices may not be compatible with the Samsung TV. (Such as Samsung 4K TV, remember you need to use usb 3.0 to stream 4k smoothly...)
  • If the Index Table is in error, the Seek (Jump) function is not supported.
  • When you play MP4 video on Samsung TV over a network connection, the video may not be played smoothly.

Now you should know that when the MP4 file content can't meet the requirement of Samsung TV, certainly can't be played on it.

Note: Here is a picture from Samsung official website that shows which formats Samsung TV can support.
