Peace be upon you I am offering a used and clean projector with no issues. This projector has a distinctive version because it is 3100 lumens for white and 3100 lumens for black. Most of what is available in the market has unclear resolution because it is only 3000 for both white and black. The display screen is excellent, electric, it comes with a remote to lower and raise it to hide it. For your information, the price of the device new is over 3000. And the price of the new display screen is over 1000.
