Here my Engineering Mgr buddy gave me this great info today.
"While HD33 and HD20 do share some optical components to get the economy of scale, the electronics and chassis of HD33 is totally revamped to display 3D and enhance 2D also.
The color wheel speed is faster to give less rainbow, the new bigger chassis also makes the projector a bit quieter and no front grill eliminates the tiny amount light spill that some users have shown concern with HD20
The data bandwidth and processing power has to be at least doubled internally in order to display 3D 1080p at 120Hz
With such extra bandwidth and processing power on hand, the 2D image quality is also significantly enhanced.
DMD mirrors can now turn on and off even faster – this translates to even better color and grayscale rendering.
This improvement is more easily noticeable in a dark scene – the dithering noises are much less noticeable and give smoother dark details
This extra processing power also helps to improve the image digitally
- PureDetails, can sharpen the image selectively, the edges and corners of the image is sharpened but not the noises
- PureColor can enhance the color selectively makes less saturated color more saturated but already saturated colors will not be too oversaturated
- PureMotion – this is Optoma’s frame interpolation technology that works in both 2D and 3D, not only can it eliminate motion judder, it can also make fast action sport or action movie visibly clearer to see by adding interpolating frames. (note the default setting is a bit conservative, to intentionally keep a small amount of judder to give some resemblance of film)"
