How do I adjust the focus and keystone of the CAIWEI A6AB 4200-Lumen Wireless Android Projector?
I have set up the projector, but the image appears blurry and trapezoid-shaped. I want to know how to adjust the focus and keystone to improve the image quality.
To adjust the focus of the CAIWEI A6AB projector, follow these steps:
1. Turn the trackwheel on the projector clockwise to bring it to the end.
2. Slowly rotate the trackwheel counterclockwise while observing the image on the screen.
3. When the image becomes clear, you have reached the best focus point.
To adjust the keystone of the projector, follow these steps:
1. If the projected image has keystone distortion and appears trapezoid-shaped, reposition the projector to improve its angle to the screen.
2. If the image is still trapezoid-shaped, go to the "Trapezoid" option in the projector's menu.
3. Use the up and down buttons on the remote control to adjust the vertical keystone and the left and right buttons to adjust the horizontal keystone.
4. Alternatively, you can use the "Four Point Trapezoid" option to adjust each corner of the image to get a rectangular shape.
Refer to the user manual for more detailed instructions and illustrations on adjusting the focus and keystone of the projector.
