Electronic whiteboard projector is a kind of equipment widely used in education, office and other fields, and it is loved by users because of its simple operation and high efficiency. However, in daily use, many users often encounter blurred projection, which will bring troubles to classroom teaching and work efficiency. So how to solve this situation?

The first thing to confirm is that there are many possible causes of projection blur, which need to be investigated one by one. The following are several common reasons that may lead to projection blur and the corresponding solutions:

1. The projector lens is not completely cleaned.

When there is dust or grease on the projector lens, it will affect the clarity of projection. The solution to this problem is simple, just wipe the lens with special detergent or pure water.

2. The projection distance is not enough

If the projection distance is too short, the projected image will be distorted and blurred, and if the projection distance is too long, the image will become smaller. The solution is to adjust the distance between the projector and the projection surface to get the best definition. Different models of projectors have different theoretical projection distances, and some projectors can also adjust the definition by zooming, which needs to be flexibly adjusted according to the actual situation.

3. The resolution setting is too low

The higher the resolution, the clearer the image. If the resolution of the projector is set too low, the projected image will become blurred. Before using the projector, you should know the best resolution of your projector, and then set the corresponding resolution to get the clearest image.

4. The projection background is not clear

If the projection background is not clear, it will also affect the clarity of the projection. Therefore, when using the projector, you must choose a place with sufficient light and clear background, so as to obtain a better projection effect.

Generally speaking, if the projector is blurred, the reason should be determined first, and then the corresponding solution should be taken. If the above methods can't solve the problem, it is recommended to contact after-sales service or professional and technical personnel in time. The most important thing is that users should pay attention to correct operation and regular maintenance during use, so as to better ensure the stability and long life of the projector.
