Optoma PT105 Gaming Projector Review
Relatively good video image quality. The PT105's video quality puts most pocket projectors to shame, but that doesn't put it in the same class as a typical low-end home theater projector. The quality is best described as good enough to watch a full length movie, as long as you don't mind seeing rainbow artifacts (more on that later).
In our tests, the projector handled skin tones well, and it didn't show artifacts, posterization (shading changing suddenly where it should shade gradually), or any other glaring problems. It lost some shadow detail in poorly lit scenes that tend to cause that problem, but this shouldn't be an issue for games, where the programmed equivalent of lighting is tightly controlled.
I also saw a related issue, with some scenes coming across as a little dark overall, even though the image was bright enough for comfortable viewing. This is most likely related to the color depth of the projector's DLP-based engine, which TI says is 18 bits rather than full 24-bit color. The sense of darkness is what I would expect if the mapping were compressed in the darker shades, with multiple digital shades mapped to the same dark color and some colors mapped to darker shades than they ideally should be. Here again, this is less likely to be an issue for games, which tend to stay away from the dark shades where the compression in color mapping can be a problem.
The PT105 also offers good color balance in both video and standard modes, with suitably neutral grays. Bright mode showed a green tint at some gray levels, but color balance issues in a projector's brightest mode are common.
Good game image quality. Given the focus on game playing, the PT105's image quality for games is probably its most critical feature. As you might guess from the data and video image quality, I found the quality more than good enough to handle game images without serious problems.
Small and Portable. Weighing in at just 1.9 pounds and measuring 3.2" x 7.8" x 7.8" (HWD), the PT105 is small enough to take with you to a friend's house or to store away easily when you're not using it. However, Optoma doesn't supply even a soft cloth cover to protect it from scratches or dust. You may want to buy one both to protect it and to make sure the cables and external power block don't get separated from the projector.
Quick and easy setup. The PT105 is the sort of projector you're likely to be setting up every time you use it, which makes the easy setup an important plus. All you have to do is put it in place, point it at whatever you're using for a screen, plug in the power cord and cable, turn it on, and focus. The entire setup should take less than a minute.
Usable audio. The audio in most small projectors is hardly worth having, but the 1.5 watt speaker in the PT105 is better enough than average to make it worthwhile. It doesn't have the volume to fill a room, but it's loud enough to serve for two or three people huddled around the projector, which is where you'll most likely be if you're playing games.
