The BenQ W770ST is a lightweight, portable 720p projector with a short-throw lens that's perfect for living room and gaming use. Producing 2500 lumens in its brightest mode, the W770ST has the power to overcome ambient light, while its 13000:1 contrast and solid color performance make it a respectable movie projector when the sun goes down. Full HDMI 3D compatibility and a ten-watt speaker round out the projector's features, while its $799 price tag makes the W770ST a great option for those on a budget.


The W770ST comes wrapped in a sturdy soft carrying case, complete with a front pocket to hold the remote control and any necessary cables. The remote itself is a small "candy bar" model that feels good in the hand, but might get lost in the couch cushions if you're not careful.

The "ST" in the projector's model name stands for short throw, so you will want to place it on a table fairly close to the screen. A 60" diagonal image, which is about the right size for a room with moderate ambient light, can be displayed from a throw distance between 3' 2" and 3' 9" depending on zoom. That doesn't give you a lot of wiggle room, but as a portable projector, the W770ST can usually be physically moved if the zoom range is inadequate. The W770ST places the bottom edge of the projected image a few inches above the lens centerline -- on a 60" diagonal image, it's a 2" offset, for example, assuming the projector is level.

The Viewing Experience

The W770ST produces a bright, powerful image from the get-go. Light output is sufficient to illuminate a 60" diagonal screen in moderate ambient light or a 80" diagonal screen in low ambient light. Black levels are excellent for such an inexpensive projector, and SmartEco mode can make them even better in scenes with low average illumination. The W770ST's default color calibration is slightly under-saturated but accurate, averaging around 7000K across the grayscale without any adjustment. Color brightness in the W770ST's Cinema mode is only about 630 lumens, or 35% of white, but knocking BrilliantColor down can make the image appear much better balanced at the cost of white light output. (Click here for more info on DLP technology and Color Light Output).

The W770ST has full HDMI 3D compatibility, and the projector uses DLP Link to create the 3D image. 3D performance is largely dependent on which glasses you use, as the projector does not come bundled with any eyewear. Like most DLP Link projectors, the W770ST's 3D image is free of crosstalk and has very little flicker thanks to its 144Hz refresh rate.

What about rainbows and color wheel speed?

Why the heck did you review this when BenQ has released a short-throw 1080p projector?

Kiran. This Projector is a "budget" version of the 1080ST. Some of us cannot afford to pony up the extra $200-300 to purchase the 1080p model. Others budget shoppers who are not videophiles may not even care to disern differences in quality between 720p and 1080p as long as it produces a satisfactory image. Today's 720 projectors have significantly upgraded their image quality and 3D performance to levels greater than satifactory. I can attest to that with one of my projectors being an older OPTOMA HD66. Im a video/audiophile. I make concessions for quality and limited features when in using my 720p projector having knowlege of the full capabilities available in my theater room projector; the 1080p OPToma HD33. But for usage in a spare family room, the performamance of the HD66 model is pretty damn good! No complaints.
