If you play video files with the video player that comes with A788T, it is suggested that you try to play in landscape mode through the flip button above the player, and click the full screen button next to it to try to play in full screen.

If you still can't play it in full screen, the video source may be too large, which exceeds the maximum resolution that the video player can support (1080P). We recommend that you use third-party applications to support more encoding and use video rendering optimization. Individuals can consider using software such as mx player and moboplayer, and turn on soft decoding in their settings, and then turn on the full screen function of the player.
