Limitations

The IN82, like many DLP projectors, has a 1.2:1 manual zoom/focus lens with no lens shift. Most 1080p projectors under $6,000 do have some form of lens shift or a longer zoom. The IN82 has a throw offset of 36% - meaning that the bottom edge of the image will be 36% of the image height above the centerline of the lens. This is optimal for a ceiling mount in a room with a standard eight or nine foot ceiling - using a 100" or 120" diagonal 16:9 image, the picture will fall roughly in the center of your wall.

The IN82 uses a 300 watt lamp to attain its maximum 1259 ANSI lumens. This means that the IN82 throws off a lot of heat, which can quickly heat up a smaller room. It also means that the fan is louder than most competitive models, which can cause distraction if the audience is too close to the projector. In high lamp mode, the fan is easily heard from several feet away; eco-mode is quieter but still not silent. When placed next to most other 1080p projectors, the IN82 is clearly louder.

When you consider the fixed throw angle, short zoom range, loud fan and higher than average heat dissipation, it is clear that the IN82 should be ceiling mounted in a room with good ventilation. A shelf mount behind the seats would be difficult due to limited zoom and fixed throw angle, while placement between the seats or on a coffee table would expose the audience to excessive heat and audible noise.

The IN82 has a 4x-speed color wheel. Those who are sensitive to DLP color separation artifacts may see them when watching the IN82. Color separation artifacting, also known as the "rainbow effect," is a phenomenon where the viewer sees momentary flashes of color that look like a rainbow when an object moves quickly across the screen. This is most noticeable in high-contrast images where a bright object travels across a dark background.

The speed of the rotating color wheel determines how often rainbows are experienced, and by how many people. When people started using commercial DLP projectors for video and home theater, their 2x speed wheels caused many people to see rainbows. Business DLP projectors today still use 2x speed wheels, but due to their intended use (static content on a smaller screen versus full motion video on a larger one) rainbows are not often a problem. Meanwhile, the bare minimum color wheel speed for single-chip DLP home theater projectors today is 4x. This speed eliminates the rainbow effect for most people, but not nearly all of them. Many home theater projectors now use 5x or 6x speed color wheels, which further reduces the percentage of the population sensitive to color separation artifacts to just a handful of folks.

For this reason, it is recommended that you audition either the IN82 itself or another DLP projector with a 4x speed color wheel before making your purchase. While most people are unaffected by rainbow artifacts, it can be a deal-breaker for those who can see them.

Finally, the IN82's remote control is somewhat poor. While the remote does have a backlight, this only illuminates the symbols on the remote's buttons, while the labels remain dark. This means you'll have to remember what all those symbols mean - which defeats some of the purpose of having a backlight to begin with. Also, the IR signal range is limited. We could not bounce the signal off the screen at a distance of ten feet, but instead had to point the remote at the projector itself.
