Optoma HD25 Home Theater Projector Review
2D image quality. The HD25 puts an image on screen that, for lack of a better term, "looks expensive." It has excellent, natural, well-saturated color, even without any adjustment. The color gamut has some minor errors, but the HD25 has a full color management system for those with the time and inclination to fix them. Grayscale tracking is quite good, measuring a consistent 6400K straight out of the box; a simple -3 to green produced near-perfect 6500K. Dynamic range is somewhat hindered by the projector's middling black levels, but this is a common flaw in inexpensive DLP 1080p projectors and not unique to the HD25. We did not see any loss of shadow detail, in any case.
3D. The HD25 is a Full HD 3D projector, capable of displaying 3D content in any of the formats listed in the HDMI 1.4 specification. The projector is compatible with both DLP Link and radio frequency (RF) sync systems. The DLP Link system requires no emitter, while the RF system uses an outboard emitter that connects to the standard VESA port on the projector's connection panel. Since RF synchronization does not require line of sight, you can place the emitter anywhere.
When watching 3D content, the picture is artifact-free. There's no sign of crosstalk or jitter of any kind, and images are detailed and true to the source material. On the other hand, displaying 3D on anything larger than a 100" diagonal screen makes for a relatively dim picture, since 3D viewing takes away so much of the projector's high light output.
Great for gaming. The HD25 has all of the hallmarks of a great gaming projector. It has high light output, allowing it to be used even when some lights are on. It has accurate color and good dynamic range, so color and shadow detail is never lost. 1080p resolution makes the picture sharp and crisp. A long-life lamp allows for long gaming sessions without concern for bulb blowouts. Last but not least, the HD25's low input lag of 17ms (1 frame at 60 fps) means that even the most demanding fast-action gamers will be able to play without concern.
Long life. The HD25 has an estimated lamp life of 3,500 hours at full power and a whopping 6,000 hours in Eco mode, putting it right on par with its low-cost 1080p competitors. In real-world terms, that's one two-hour movie per day, every day, for almost five years at full power or over eight years in Eco mode.
Onboard audio. With 10W stereo speakers (5W per speaker), the HD25 offers an onboard audio system that is actually worth using. While it is no match for dedicated speakers, the onboard audio allows the projector to be used as a portable entertainment device whenever the situation requires it. Whether you want to set up a game console for the kids or watch the game in the living room instead of the theater, the HD25's speakers are loud enough to be a viable audio option in the absence of a dedicated system. The speakers do start to break up if volume is raised to maximum, but anything up to about 8 (on a scale of 0-10) is usable.
