This may be the smallest and the most convenient projector in the world to offer 4K resolution. Ordinary projectors in the form of a flat cube must be installed on a table or tripod, which is very complex and troublesome process. This has improved the complex installation process through a vertical form factor and reflector. The installation is completed just by placing it on the floor, and video in 4K can be projected to the wall in front or on the ceiling through the reflector. It is a totally new type of projector that was designed to consider the viewpoint of users.
