BenQ W770ST
720p DLP Home Video Projector Review

Bill Livolsi, October 8, 2013

Key Features

Portable. At only six pounds, the W770ST might not be light enough for a businessperson who's constantly on the road, but it's more than portable enough to lug over to a friend's house for games or sports viewing. The projector's included carrying case feels sturdy, while the onboard speaker provides sound output when no other option is available.

Short throw. The W770ST's short throw lens makes it ideal for setup in small rooms. The projector can create a 60" image from a little over three feet of throw distance. This allows it to be placed on a coffee table in the front of the room, rather than the middle of the room, thereby giving the audience some extra space in which to move around.

Full HDMI 3D. While the W770ST isn't a 1080p projector and therefore can't truly be called "full HD 3D," it is completely compatible with 3D transmission formats outlined in the HDMI 1.4 specification. In other words, you can easily hook up a Blu-ray player or set-top box and watch 3D content.

The W770ST uses DLP Link for glasses synchronization, so all you need to do is buy some 144Hz glasses and hook up a source. There are a wide variety of 144Hz glasses available, and some cost as little as $30 per pair.

SmartEco. The W770ST uses SmartEco to boost contrast and reduce power usage. SmartEco is a third lamp setting (the other two are Normal and Eco) which interprets the brightness of the content on screen and then adjusts lamp power to an appropriate level. This has the effect of making highlights brighter in bright scenes and shadows deeper in dark scenes while also reducing power consumption. Unlike previous implementations of lamp-based brightness control, SmartEco has no noticeable effect on fan noise.

Onboard sound. A 10W mono speaker is the W770ST's answer to mobile, no-hassle sound. This speaker is powerful enough to accommodate small audiences of no more than 4-6 people in quiet rooms, and is more than loud enough to be heard over the projector's fan noise. In 3D mode, when fan noise is higher, you may have to increase speaker volume to maximum in order to compensate.

Long lamp life. The W770ST's 210W lamp is expected to last up to 4,000 hours at full power or 5,000 hours in Eco-mode. However, SmartEco mode can extend lamp life up to 6,500 hours, though this also depends on what kind of content you watch.

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.
