BenQ W770ST
720p DLP Home Video Projector Review

Bill Livolsi, October 8, 2013


Visible pixelation. Since the W770ST has a native resolution of only 720p, pixelation can become visible when the audience is seated too close to the screen. We began to notice visible pixelation when seated closer than 1.5 times the screen width. Using a 60" diagonal image, that puts minimum viewing distance at six and a half feet if you want to avoid pixelation.

Color light output. There is a large gap between white light output and color light output, such that highly saturated areas of color can appear undersaturated and dull next to white highlights. This can be corrected by reducing BrilliantColor, but this also drops white light output by 56%.

Truth is, if you are watching a movie or television show, very little of the content on screen is actually made up of bright white highlights. You are already getting this reduced light output in every area of color on screen, regardless of how you set your projector. Reducing BrilliantColor restores the balance between white and color, and chances are you won't find the projector much less bright overall. You can leave BrilliantColor turned on when light output is the primary concern, but be sure to reduce it when the sun goes down and it's time to watch a movie.


The BenQ W770ST is an inexpensive living room projector with solid image quality that's perfect for gaming or portable use. A short-throw lens keeps the projector out of the way, giving you more room space to work with, while a 10W onboard speaker can provide sound output when there are no other options. Compression of 1080p sources is clean and crisp, and there's not much detail loss. Full HDMI 3D compatibility makes the W770ST an affordable option for entry-level 3D movies and gaming, especially since the projector uses inexpensive DLP Link glasses.

On the downside, the W770ST's BrilliantColor increases white light output without also boosting color light output, and at its default settings color can appear dull and undersaturated as a result. Reducing BrilliantColor solves this problem but also cuts lumen output by more than half. And since the W770ST is native 720p, pixelation can be seen when sitting too close or using a too-large image.

Overall, the BenQ W770ST is an inexpensive purpose-built video projector that offers solid image quality without the usual video projector price tag. If you need a living room projector and have a tight budget, this may be the one you're looking for.

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.
