This projector was working and excellent and had no issues. Suddenly it turned off and I swear I don't know what its problem is, maybe a fuse or something. I took it to a guy, and God is my witness, but I expect its problem is simple and I don't need it, so I put it up for sale. The device is very excellent and it has sound too. The serious buyer is welcome. Very high clarity. Connectivity: HDMI Brand: BenQ Refresh Rate: 60Hz Resolution: Full HD Type: Projector
