For a 120" diagonal image, the M353WS's lens centerline is about 9" below the bottom of the screen image which suggests tabletop or cart mounting. To get a 120" 16:10 image the unit needs to be set back from the screen about 46 inches. See our Projection Calculator for throw distances required for your screen size. The Calculator functions based on throw specifications provided by the vendors, the accuracy of which can vary somewhat. So do not plan precise placements for a particular screen until you have the unit in hand and can match the actual image to the screen. Since this projector has no zoom lens there is no leeway for image size adjustment other than to reposition the projector.
The M353WS can be ceiling mounted, but a long extension tube may be required to get the image properly placed on the screen.
Angular projection surfaces. Generally, the M353WS should face the screen squarely to project an undistorted image. However, there are times when the projection surface is not orthogonal to the projector. For those situations, the Image Express Utility Lite supplication can make individual corner corrections to square up the image.
Screen Flatness. Short-throw projectors like the M353WS project upward at about a 40° angle to the screen. Any waviness in the screen surface (as you will find in a pop-up screen) will cause a distortion in the image. If the waviness is minimal, the distortion will only be noticed at the edges of the screen, but if it is severe (e.g., projecting on a sheet tacked to a wall), the distortion will affect the entire image.
Lamp life and brightness. As with all lamp-based illumination systems, the M353WS's lamp will grow dimmer with time. One way to mask this drop in brightness is to run the projector in one of its two Eco modes during its early life, and switch to full power later in the lamp's life. The overall effect is a relatively constant brightness over the life of the lamp. Of course, this approach depends on the ambient light conditions allowing reduced brightness in the first place, but our test unit suggests that the M353WS is a good candidate for this method since it is initially brighter than its specification.
