When your gobo projector appears to be clear on one side and blurry on the other, there may be several reasons:

Lens contamination: the lens of the projector is susceptible to dust or dirt, which can lead to uneven light scattering, which in turn produces the phenomenon that the projection picture is clear on one side and blurred on the other.

Projection distance is not appropriate: the clarity of the projector and the projection distance is closely related. If the projection distance is too far or too close, it will lead to the projection picture is clear on one side and blurred on the other.

Skewed projection screen: If the projection screen is not horizontal, it will also lead to the projection picture is clear on one side and blurred on the other. You can solve the problem of skewed picture by adjusting the vertical and horizontal position of the projector.

Aging Lamp: The lamp of the projector has a limited life span, if the lamp has been used for a longer period of time, the projection picture may be clear on one side and blurred on the other. At this point, you need to consider replacing the bulb with a new one.

In order to solve the projector projection picture is clear on one side and blurred on the other, you can take the following measures:

Clean the projector lens: use a soft cloth to clean the lens of the projector and make sure the surface of the lens is clean and dust-free. Avoid using cleaners that contain alcohol or ammonia to avoid damaging the lens.

Adjust the projection distance: Adjust the projection distance according to the specifications and instructions of the projector to make the picture clear and natural. If the projection distance is too far or too close, try to adjust the distance until you get the desired clarity.

Calibrate the projected picture: Make sure the horizontal position of the projected picture is level with the position of the projector. If you find that the screen is skewed, you can use the projector's adjustment function to fine-tune the vertical and horizontal positions to obtain a balanced projection.

Lamp Replacement: If none of the above methods work and the lamp has been in use for a longer period of time, it may be necessary to consider replacing the lamp with a new one. Please refer to the user manual of the projector or consult the manufacturer on how to properly replace the lamp.

With the above measures, you should be able to solve the problem of the projector projection picture is clear on one side and blurred on the other. If the problem persists, it is recommended to consult the manufacturer of the projector or a professional repairer for more detailed help and support. The quality and performance of the projector can also have an impact on the clarity of the picture, so it is also important to choose a reliable brand and a model that suits your needs when purchasing a projector.
