4 Different Ways to Adjust the Image with JIRENO CUBE4

To ensure that JIRENO CUBE4 presents a rectangular image, you can adjust it via the keystone correction or four point correction.

Keystone Correction

If you should bump against CUBE4 inadvertently, letting it move slightly out of place, the keystone correction will quickly calculate the change in keystone error and readjust the image in time. Although it only supports vertical keystone correction for now that you can only adjust the length of the image to achieve a rectangular image, its auto-focus and four point correction function will make up for this shortcoming, and it will not affect your use.

Focusing

When turning on JIRENO CUBE4, it will focus automatically according to the distance between the projector and the wall. If you move the projector substantially, the clarity of the image may take a few seconds to adjust via the auto-focus.
