Why are videos not playing smoothly when using the Xiaomi Smart Projector L1?

If videos are not playing smoothly when using the Xiaomi Smart Projector L1, please refer to the following details:
1. Please determine whether you are playing online videos or local offline videos (stored in the USB drive);
2. If you are playing online videos, it will be caused by low bandwidth at home. It is recommended that you switch the video definition, for example, switch the video resolution to 720 or standard definition to see if playing videos is smooth. If the video is playing smoothly after switching to a low bitrate definition, it means that there will be a problem with the network. It is recommended that you increase the network speed or restart the router to try. If the problem persists after switching, try playing other videos. If other videos are normal, it means that the resolution of the video source is not suitable for viewing on this device;
3. If playing videos is not smooth when playing local offline videos (stored in the USB drive), you can try replacing the external USB drive, hard disk, or video source. If only one video is not smooth and the others are normal, the video has a high bit rate, causing the playback to be not smooth. Please replace other video sources. If the problems persist, it will be the external device problem.
