What should I do if the projector casts light spots on the side?

Side-projection facula of projector means that when using side-projection projection, there are some problems such as polarization, color spots and blur on the edge of projection screen, which will seriously affect the projection effect and audience's perception. To solve this problem, we can adopt the following methods:

1. Adjust the projection angle. Adjusting the side projection angle of the projector to the best state can effectively reduce the spot problem. The specific adjustment method can be adjusted by adjusting the angle of the projector or correcting the deviation of the projector.

2. Adjust the screen position. The position of the screen is slightly higher than that of the projector, which will make the picture appear better at the edge, thus avoiding the problem of light spots.

3. Replace the projection screen. Some projection screens are not smooth enough, and there are many tiny depressions and protrusions. These small details will lead to the formation of light spots on the edge of the picture. Therefore, replacing a projection screen with better texture can alleviate the spot problem.

4. Adjust the ambient light illumination. Usually, too strong or too weak ambient light will affect the projection effect. Therefore, the illumination of ambient light should be adjusted according to the actual situation, and the projection effect will be better in a dark or dark environment.

5. Replace the projector. In some cases, replacing a new projector is also a good choice.

In a word, there are many solutions to the problem of projecting light spots on the side of the projector, and the specific measures need to be comprehensively considered and applied according to specific problems and different situations.
