PiP
Picture in Picture (PIP) means displaying two images (video or photo) from two different sources next to each other.
FOV
FOV (Field of view) is the angle formed between your view and the projected image. The closer you are to the image and the longer the diagonal, the greater the angle, and vice versa.
Keystone correction
Keystone correction is a function that corrects the output image if a projector is not placed perpendicular to the horizontal centerline of the screen (too high or too low).
Resolution
The native resolution is the number of pixels (pixels) a projector can horizontally and vertically project. Generally, the higher the native resolution, the more detailed the picture and the bigger working or gaming area it will provide.
