All three of these new projectors will be equipped with BrightEra 3LCD Inorganic Panel technology in addition to energy efficient features and flexible installation options, allowing you to literally have the most efficient setup possible based on your situation.
The VPL-CW275, which is a part of Sony's existing CW225 line, comes with one of the brightest outputs that the company offers. In addition to that, this projector has a new Picture Muting feature that allows for the picture to be switched off instantaneously for a brief period of time by pushing a single button. Also included with the VPL-CW275 is a lens shift range and screen fitting feature that allows you to easily adjust the device after installing.
The VPL-FH31 and VPL-FH36 projectors are both enhanced replacements for Sony's existing VPL-FH30 and VPL-FH35 projectors. They are also said to offer the best in class image quality with both projectors providing WUXGA 1,920 x 1,080 resolution and full HD compatibility.
Each of these projectors is expected to be released sometime between now and January 2013, according to Sony. Unfortunately, the company has yet to announce at this time a pricing scheme for these devices.
