What if the nut projector is blurred?

Nut projectors have always been very popular. Of course, many users are asking how to adjust the picture clarity of the nut projector. You can refer to this tutorial of mine, and I hope it will help you.

Nut projector adjusts the clarity of the projection picture tutorial: adjust the focus ring (rod) of the projector to adjust the clarity of the projection picture to the best state.

1. Universal projector: the focus ring is on the lens (note: some projectors need to open the A/V mute slide on the lens to see it). As shown in the figure below:

Other factors and methods: In addition, the following factors will also blur the projection picture. After the above methods are invalid, please check and act accordingly:

1. Distance between the projector and the screen: beyond the zoom range of the projector, the image will become blurred. Baidu's "Projection Distance Calculator" can be used to calculate the optimal placement distance of the projector.

2. "Trapezoidal correction" adjustment will reduce the quality of the projected image. It is suggested that you try to reduce the tilt angle of the projector up and down, left and right, and try to reduce the effect of trapezoidal distortion.

3. There is dust or stain on the surface of the projector lens. Please gently wipe the lens with a commercial soft cloth or lens paper to clean the glass;

4. The condensation on the lens surface will affect the image quality. When the ambient temperature changes, condensation will occur. Please leave the projector for an hour or two before use.
