1080p 3D Home Video Projector
February 9, 2013
2D image quality. While the W1070 isn't a projector with a lot of bells or whistles on it, the projector's 2D image quality is excellent. The projector comes out of the box with three perfectly usable 2D image modes, a 3D mode, two locked ISF modes that become available after calibration, plus three User image modes for customization. These modes help the projector cope with the myriad different situations in which a home video projector might be used, from a darkened theater-type environment to a bright living room on a sunny Sunday afternoon.
3D Performance. The W1070 uses the DLP Link system to display Full HD 3D, meaning that the image is punctuated by white light pulses which are used to sync with active shutter 3D glasses. This has both positive and negative consequences. A positive consequence is that DLP-Link systems tend to be very low in crosstalk, and indeed the W1070 had no visible crosstalk during our testing. On the other hand, DLP Link glasses tend to lose synchronization more easily than either infrared-sync or radio-sync glasses, which can be a concern in any environment where people get up and move around. Either way, the W1070 is one of the few home video projectors to feature Full HD 3D.
With decent out-of-the-box color and respectable contrast, the W1070 is a great little projector for entertaining in your home. By far the best part of the image is its natural sharpness and clarity. This isn't just due to the projector's 1080p pixel matrix, either; the W1070 has a razor-sharp image even for an HD projector--especially one in this price range.
Long life. The W1070's long-life lamp makes it an attractive projector to serve as a partial TV replacement. Lamp life is estimated at 3,500 hours in full power mode and up to 6,000 hours in Eco or SmartEco mode, which is considerably longer than comparable projectors. This is in part because the W1070 is capable of reducing lamp power by up to 70% using the projector's SmartEco function, which dims the lamp output to a level appropriate for the content on screen at the time of selection. There's no way to make an arbitrary brightness selection, which is unfortunate, but the concept itself is useful when you don't need a lot of light.
Onboard audio. Part of the allure of home video projectors is their use as TV replacements, and TV replacements need some kind of onboard sound capability. The W1070 doesn't have much of a speaker system; it has a single 10W speaker rather than the stereo sound that some competitors offer. But that one speaker doesn't suffer from distortion or the tinny character that plagues many small speakers. Indeed, with the volume cranked, we found the single speaker more than adequate for an audience of eight in a large living room.
Placement flexibility. The W1070's manual zoom lens has a 1.3:1 ratio, and can display a 100" diagonal image from 8' 4" to 10' 11". That's about standard for this class of projector. What is not standard is the projector's vertical lens shift, which gives you the ability to move the projected image up or down by about 10% of the image's height. The range is such that, at the bottom, the bottom edge of the projected image is level with the lens centerline, and at the top it has an upward throw angle equivalent to roughly 20% of the image's height. This makes table mounting and ceiling mounting the most realistic options, while a rear shelf mount is more or less out of the question both due to lens shift and zoom concerns.
6X Speed Color Wheel. The W1070 has a six-segment color wheel in the theater-optimized RGBRGB configuration. This wheel layout maximizes color without artificially boosting white, and is preferred for its ability to render natural color. What's more, the wheel gives an effective refresh rate of six times per frame. This should eliminate color separation artifacts (rainbows) for all but the most hypersensitive of viewers.
