minimum for the Prismasonic horizontal lenses, for instance. Having the lens inset doesn't help any either.
We responded to users' concerns that the previous throw ratios we had in our products were too long. In general, the shorter the throw, the more rooms the projector will fit into.
Will all three models have the proper 2.35:1 stretch mode with no image cropping needed for anamorphic lens usage on all video resolutions (from 480i to 1080p)?
The "Letterbox" resizing mode can be used for anamorphic lenses. This mode chops the top and bottom 1/8 of the image off and stretches the remaining image to fit the 16:9 display. Typically it would be used for non-anamorphic DVDs but it stretches anamorphic content the same amount that an anamorphic lens should unstretch it. It works the same way for all input types.
Will your Pixelworks scaler properly "weave" 1080i signals, and not "bob" those signals to 540p (you only get half the vertical resolution of the original signal by bobbing 1080i) before conversion to the native resolution of the panels? That is an issue with many HDTV's internal scalers on the market.
Yes. Not only will it properly deinterlace film-sourced content at all resolutions, it will also smartly deinterlace video based content to reduce jagged edges.
Will your new projectors accept all forms of 1920x1080p signals from the new Blu-Ray and HD-DVD format players (those that properly output 1080p video, that is)?
Yes. They all accept 1080p at 60 Hz and 24 Hz.
Will the optic pathway, DLP chip and color wheel, and lens assembly, etc. all be sealed for no dust blob issues?
The optical engines are dust resistant with all major dust paths gasketed. This is a great improvement over the SP4805 but the engines are not completely sealed.
