1. First, put the projector in a proper position and adjust the lens. Make sure that the projector is vertically aligned with the curtain and is not tilted.
2. Next, make some basic settings for the projector, such as the adjustment of brightness, color saturation and contrast. These settings will help ensure that the projected image looks more realistic and clear.
After the projector is installed, you need to adjust the curtain. Make sure that the curtains are tight and there are no wrinkles or ripples. If so, it may be necessary to reinstall or adjust the position of the curtains.
4. Then use the test image or video to adjust the position of the curtain and the light source of the projector. Align the curtains and adjust their height and tilt angle to ensure the symmetry and clarity of the image.
5. Finally, fine-tune each scene as needed. For example, you can fine-tune the color temperature, brightness and contrast to suit different projects, such as documents, presentations or video playback.
These are the basic steps of the projector screen calibration method. Correctly calibrating the projector and curtain will ensure that the projected image will minimize unnecessary distortion, thus improving the display effect and the quality of light and shadow experience.
