Do not use it as your main display like a TV or monitor; use it as a secondary display. You will likely be dissatisfied if you use it as your main display. Please consider purchasing a projector that is reasonably priced. The images show how it looks when projected, but it seems that there are many parts where text is unreadable. Do not expect the clear image quality of a TV or monitor. Videos seem to be fine. It supports controller games, but it is not suitable for games that directly control with a smartphone. The recommended projection distance is 1.5 to 4 meters. If the distance is less than 1.5 meters, the focus will not be corrected, so adjust the focus by moving to a distance where it can be corrected.
