1080p D-ILA Home Theater Projector

Input lag. When it comes to gaming, especially fast-paced gaming that requires quick reflexes, input lag matters. Input lag measures the time between a signal's arrival at the projector and the time that it is displayed on the screen. We measured the X55's best performance at 68 milliseconds, or four frames at 60 frames per second.
Compared to other recent projectors, that's fairly slow. Some 2D projectors clock in at 17 milliseconds, while the best 3D projectors measure about 34 milliseconds.
Highly sensitive to ambient light. The X55 can display low-end super-deep shadow detail. However, to bring this detail out, the theater room needs to be very dark and non-reflective. Many people do not have the time or inclination to black out their rooms in this way, and for those people, the X55 is "too much projector." While you can certainly use the X55 in a room with imperfect light control, it's a bit like owning a Ferrari in a town where the speed limit on every road is 35 miles per hour. Sure, the projector is capable of more, but you'll never get to experience it.
Complicated menus. The X55 has a lot of options and as such there are a lot of adjustments available. That said, there are some things that could be done better. Gamma preset selection and gamma customization are on separate pages, for no discernible reason. The gamma presets are lettered (A-H) rather than numbered, even though most people buying the X55 will know what gamma correction is and whether they want 2.2 or 2.4 or something else entirely.
Fan noise. While low lamp fan noise is whisper-quiet, the fan noise with the lamp on full power is a different story. The X55 is noticeably louder than its competitors and much louder than the best 1080p projectors in its price range. Many people install their projectors in such a way that fan noise is less of a concern, but if you and your audience are seated near the projector itself this is important to keep in mind.
