CASIO XJ-UT310WN Short Throw
LED/Laser Hybrid Projector
June 16, 2014
For my tests, using a 92-inch diagonal image at the native 16:10 aspect ratio, the front of the projector was 14" from the screen and the window that serves as the lens 9" farther away.
The projector weighs 12.1 pounds, making it light enough to move from room to room, with or without a cart. However, it is best installed permanently. As with any ultra-short throw projector, getting the image geometry and focus right is tricky, because you're too close to the screen to see the effect of each adjustment. It helps to have someone standing behind you who can see the whole screen at once and tell you how it looks as you make changes.
The obvious choice for installation is to put the XJ-UT310WN above the screen with Casio's optional $200 wall mount. However, you can also put it on a flat surface below the screen, which is how I tested it. Either way, the lens offset puts the closest edge of the image--meaning the top or bottom--about 18% of the picture height below or above the projector.
For setting up on a desktop, you can move the image up or down, and adjust yaw, with two adjustable screw-on feet near the back plus one in the front. You can then adjust keystone, if necessary, with the remote.
