ive own this projector for a 2 month and now the bulb over heat and it shut the bulb off and go to emergency cooling mode . I call amazon and they say I need to call Benq . I will update with they response . the color and option be great but surely I must have a defective bulb or unit . I use it to watch 2 movie and to project art on a wall . I might have use it for 7 hour max before I run into issue
