Optoma PT105 Gaming Projector Review
Brightness. I measured the PT105 in its brightest mode at 79 lumens, or about 5% more than its rating. Standard mode was 44 lumens, and video mode, which I used in most of my tests, was 53 lumens. With the lights out, I found video mode bright enough to settle on a 63" diagonal image for comfortable viewing. With moderate ambient light I dropped the size to 45" diagonal.
Excellent brightness uniformity. One of the more pleasant surprises for the PT105 was its excellent brightness uniformity, with no visible variation in brightness even with a solid white screen. This level of uniformity, which I measured at 90%, is one of the factors that helps make the image look so good compared to pocket projectors.
Connectivity. The PT105 offers three sets of connectors. The back panel includes a VGA port for a computer or component video along with three RCA phono plugs for composite video and stereo audio input. In addition, there's an HDMI port on the right side.
Optoma supplies a combination composite video and stereo audio cable. However, you'll probably want to take advantage of the HDMI port, which means you may want to order a cable when you buy the projector. If you want to connect to the VGA port, you'll need a VGA cable or a component video cable and adaptor as well.
No zoom. With no zoom lens on the PT105, the only way to adjust image size is to move the projector. This shouldn't be a problem given the light weight. However, if you want to hear the low-volume audio, you'll have to move with the projector when you adjust the image size. I measured a 45" diagonal image from 7.3 feet, and a 63" image from 10.2 feet.
No remote. Optoma doesn't provide a remote for the PT105. You have to use the buttons on top of the projector to adjust volume, change the source, or change menu settings.
Rainbow artifacts. xssRainbow artifacts are potentially an issue for any single-chip DLP projector, and particularly for projectors that use LEDs. For the PT105, that translates into showing rainbows relatively often. If you see the rainbows easily, as I do, odds are you'll find them annoying for watching a full length movie. However, they show up far less often in games than in video. You'd have to be even more sensitive to them than I am to consider them a problem for game playing.
