Projector horizontal trapezoid cause

The projector horizontal trapezoid problem means that the projected image appears wide at the top and narrow at the bottom when the projector is working, similar to a trapezoid. This problem is caused by a variety of factors, including the following:

1. Projector direction is not correct: If the projector position is incorrect or not smooth, it will lead to tilted images, resulting in a horizontal trapezoid problem.

2. Projector lens deviation: If the projector lens position or angle deviation is too large, it may lead to image deformation, thus the horizontal trapezoid problem.

3. Incorrect setting of projection mode: If the projection mode of the projector is set incorrectly, which leads to distortion of the image, the horizontal trapezoidal problem will occur.

4. Wrong distance between the projected object and the projector: If the distance between the projected object and the projector is not in accordance with the standard, it will have an effect on the image, and thus the horizontal trapezoid problem will occur.

5. Uneven surface of the projector: If the surface of the projector is uneven or tilted, it will also affect the display quality of the image, which will lead to horizontal trapezoidal problems.

Therefore, to solve the horizontal trapezoidal problem, we need to scrutinize the above reasons, and make timely adjustments and corrections. Can be used to adjust the projector position, lens position and angle, adjust the projection method, adjust the distance between the projector and the projector, adjust the projector surface and other measures to solve the problem.
