Short throw. Short throw projectors are nothing new, but short throw projectors being used for home theater are relatively recent. These projectors are useful in rooms where a traditionally lensed projector takes up too much room and can be ideal for table placement in temporary setups. This also makes them great candidates for portable use, especially when they include a speaker as the W1080ST does.
For gamers, the W1080ST allows you to sit closer to the screen without getting in the way of the projected image. This is especially helpful when using a motion-sensitive system like the Kinect or Wii, where body motions are part of the game's input. A short-throw lens makes the W1080ST behave more like a television or computer monitor and removes some of the projector-specific setup concerns that gamers often run into.
2D Image quality. The W1080ST has a lot going for it when it comes to the actual image on screen. The projector's three main precalibrated image modes are all useful in some way, and those who want further customization will be pleased to hear that the W1080ST supports ISFccc calibration to unlock the projector's ISF Day and ISF Night image modes. Using the projector's various image modes, it is not hard to tailor the projector's image to the viewing environment in order to create a picture that is bright, vibrant, and life-like.
Full HD 3D. The W1080ST's DLP link 3D system, which runs at a brisk 144Hz, is capable of displaying full 1080p 3D content from broadcast or Blu-ray disc. The DLP Link system uses light pulses between frames of the projected image to synchronize the viewer's active shutter 3D glasses. The system is low in crosstalk and had no visible flicker during use, but DLP Link is disliked by some videophiles because it is the only 3D sync system to mess around with the actual picture on screen. And while DLP Link glasses are inexpensive compared to other 3D glasses, they also lose synchronization more often due to their reliance on direct line-of-sight communication with the projected image.
Long life. Like the W1070, the W1080ST's lamp is rated to last 3,500 hours in full power mode and 6,000 hours in Eco or SmartEco mode, far beyond the typical lamp life for this class of projector. This allows you to purchase fewer replacement lamps (assuming, of course, that the manufacturer's specs are accurate) and spend less money on maintenance.
Onboard speaker. With a 10W speaker built in, the W1080ST carries its own sound along with it. Now, a single 10W speaker is not a replacement for a real sound system, but several other projectors in the W1080ST's price range either offer dinky 2W speakers or no sound at all. When you're looking for a quick and dirty option, the W1080ST at least has volume going for it. And even at 80% of max volume, the speaker did not distort or sound particularly tinny.
Color wheel. The W1080ST shares the W1070's fast 6X speed RGBRGB color wheel. This does two things: one, it almost completely eliminates rainbow effects for most viewers; and two, it keeps the W1080ST's color light output at 100%. The artificially boosted screaming-bright highlights of many inexpensive DLP projectors are nowhere to be found, and in their place are rich, accurate colors in perfect balance with the rest of the image.
