I understand that some projectors are now being shipped with 4x3 chips that have been modified to only use a 16x9 portion of their surface area.


Is that true? What have they accomplished by doing this? If this is a good thing couldn't all projectors ship at 4x3 and then if you want to use 16x9 just do it at the home by firmware?

The point of the Matterhorn 1024x576 chip is to have a 16x9 chip at a lower cost than the HD2 chip. The resolution is perfect for PAL dvd and higher than required for NTSC dvd. The advantage over an XGA chip is gain in contrast and brightness. The reason for this is no unused portion of the chip when viewing 16x9 material, as there is in a 4x3 XGA panel. The bulb can be more closely focused on the chip and there is less unwanted light reflected out of the device. The resolution of the 1024x576 is the same as XGA when viewing HDTV and dvd sources. The picture looks better for the above reasons, plus the fact that most manufacturers are also using a higher speed color wheel wth the Matterhorn. This is optimized for home use, not for commercial data presentations.
