    Integrated speaker

    Complete your home entertainment experience with the convenience of a powerful built-in speaker for exceptional sound quality and an easy set up without the need for costly external speakers.


    Most movies are shot at 24 frames per second (fps). To preserve the purity of the original image, Optoma projectors can accept high definition sources at 24 fps to display movies exactly as the director intended.


    Use the USB-A port to power an HDMI dongle, such as Google Chromecast.

    Four corner correction

    Four corner correction enables the keystone of the projector to be adjusted in both the vertical and horizontal plane, so you can individually warp each corner of the projected image to make it perfectly square. Ideal for uneven walls or in spaces where the projector placement is awkward or limited and needs to be installed at an angle.

    Wall color adjustment

    Don’t have a white wall or a projector screen? No problem! With the “Wall Color” setting, you can alter the projected image based on the color of your wall. With six options to chose from you can easily adjust for blackboard, light yellow, light green, light blue, pink and grey walls to get the most accurate color gamut.

    Why do I need to contact you in order to place my order?

    As an authorized dealer for the product you are looking at, is bound by certain agreements with our manufacturer partners in how we display, price and sell certain products.

    Some items may not be able to be advertised below a certain price or any pricing at all and others may not be able to be added to a shopping cart via an “add to cart” button.

    If a competitor’s website has the same product but is not restricting the display/functionality in the same way that you see here on, than that competitor is likely NOT an authorized dealer.

    What does that mean for you as the customer? It is very likely that the manufacturer may not honor your products warranty, or that your product was never intended for the US market to begin with.
