Other projectors in this price range include the InFocus ScreenPlay 7210.
LCD projectors are notorious for what is known as the "screen door effect", which are little lines that criss cross the picture, making it look like you're viewing the screen through a screen door. As an upgrade from Panasonic's previous model, the AX100U features something Panasonic is labeling "Smooth Screen". Every critic agrees that this technology virtually removes any kind of screen door effect at any reasonable viewing distance.
Panasonic has given the AX100U a wide range of flexibility by adding horizontal, and vertical lens shift, which lets you reposition the projected image without sacrificing quality. A 2x zoom allows for a 100" to be projected on a wall that is between 9 feet and 20' away, allowing for the projector to work within many room sizes and configurations.
The "Light Harmonizer" is a sensor that detects the ambient light in the room and adjusts the projector's brightness accordingly. In dark rooms bulb is less bright which emphasizes shadow detail, in brighter rooms bulb brightness is increased to make for a viewable picture.
Panasonic adds support for 1080p content at 24Hz and 60Hz. This allows for Blu-Ray and HD-DVD video to be displayed with no conversion and pull down eliminating the visual effect known as "judder". Standard definition video is also upscaled and deinterlaced within the projector itself.
