How to calibrate the projector?

Projector is a common image projection device, which converts image signals into light signals and enlarges and displays images on the back screen. Due to the different use environment and settings, the projector will also have problems such as unclear projection and deformation, which need to be corrected. So, how to calibrate the projector?

Correction method 1: focus adjustment

Focus adjustment is the most basic correction method, which can adjust the focal length of the projector and realize the definition adjustment of the picture. Focus adjustment is generally located on the front or side of the projector, and the focus can be adjusted by rotating the adjusting ring.

Correction method 2: adjust the arc deformation.

If the projection screen has obvious arc deformation, you can find the "Keystone" or "DistortionCorrection" option in the projector menu and manually adjust the parameters of arc deformation to solve it.

Correction method 3: adjustment of projection distance and angle.

The adjustment of projection distance and angle is very important for the size and position of the projection screen. If the projection distance is too far or too close, the picture will be distorted or too small; If the projection angle deviation is too large, it may also lead to tilt or distortion of the picture.

When adjusting the projection distance and angle, you can adjust it through the option of "Position" or "Screen Fit" in the projector menu.

Conclusion: When calibrating the projector, we must be careful and choose different calibration methods to adjust according to specific problems. At the same time, we should also pay attention to the ambient light and background color to avoid affecting the screen display.
