If you set the keystone to 0 (centered), then you will have no problem getting the entire image focused crisp and clear!Unfortunately, if you hang the projector from the ceiling, this will be a major issue.

Focus is a tad soft on the corners but as long as your screen is flat and your projector is not at an angle, you should be fine and is not noticeable

Responsive and they communicate well and are focused on pleasing their customers

Adjusted to the correct zooming and angle u’ll get a super clear image
