Unfortunately, in actual use, we sometimes encounter the "material error" of the projector. This is usually caused by the following reasons:
First, the file format is incompatible. Sometimes the PPT, video, music and other materials we make on the computer may not be completely compatible with the format required by the projector. Common problems are high or low resolution, format mismatch, incorrect coding and so on. In this case, you can consider remaking the material, trying different playback software and replacing it with a more compatible device.
Second, the interface connection problem. The projector needs to be connected with the interconnected devices through cables, wireless networks, etc. If the connection mode is improper or the connecting cable is loose, the material cannot be transmitted or the picture is blurred, and the prompt of "material error" appears. At this time, it is necessary to check the connection status, replace the connection cable, restart the equipment and other methods to solve it.
Third, hardware failure. Sometimes it may be caused by hardware failure of the projector itself. For example, the life of the light bulb expires, the laser head is aging, and the speaker is damaged, which may cause the projector to be unable to play normal materials. At this time, professional maintenance service personnel are needed to repair the equipment.
In view of these problems, we can take some measures to prevent or avoid the occurrence of "material errors" Such as: check the equipment in advance, adjust the material format, prepare the spare connecting line, and maintain it regularly. This can ensure the normal use of the projector and improve work efficiency and meeting quality.
