With its short throw lens, the TH671ST is ideal for use in almost any room. Simply place the projector on a coffee table 1.5 metres from the screen and enjoy a 100 inch image. To determine the Throw Distance for where you should place your projector in the room, enter an image diagonal measurement number in the Image Size in your room. The position of the projector in your room changes because you will need to move the projector closer or further away from the screen

is still a thing with some enthusiasts and BenQ always provides a good experience. The TH671ST is a little brighter than most and that just makes it all the better. Upon putting Cloudy With A Chance Of Meatballs in the player, the projector switched immediately to its 3D picture mode. This CGI animated feature is simple in texture but abounds with bright saturated colors. I never wanted for more contrast and the depth effect was clean and clear with no ghosting artifacts or motion blur. DLP is still my favorite technology for watching 3D and BenQ doesn’t just include it as an afterthought. Performance. The TH671ST delivers usable 3D with support for DLP Link glasses only, but its 3D performance doesn't stand out from the crowd. I saw no crosstalk in my tests, and 3D-related motion artifacts are less obvious than with earlier generation 3D projectors. However they are more obvious than with most current models. The single 3D color mode is roughly as bright as Cinema mode—the least bright 2D mode—before factoring in the loss of brightness from using 3D glasses.

BenQ TH671ST Projector Specifications

Critically acclaimed for industry-leading high contrast, BenQ DLP projectors produce the most crisply defined sharpness for crystal-clear details and legible text by maximizing the fill ratio of individual pixels and employing exclusive BenQ SmartEco Technology.

BenQ recommends using High Altitude mode at 4,921 feet and above. With High Altitude on, most people will want to stay with Eco mode, which is quieter than full power mode with High Altitude off, but with a higher pitch that makes it a little more intrusive. With full power, High Altitude mode both increases volume and raises the pitch. Among the TH671ST's most noteworthy features is its 1.2x zoom, an unusual extra for a short throw. Any short throw lens lets you set up the projector close to the screen for a big image in a small room—for example, small apartments or dorm rooms. But a zoom lens adds convenience and offers greater flexibility of placement, letting you adjust the zoom, rather than move the projector, to match the image to the screen size. This is particularly welcome for portable use, where moving from one location to another means having to set up the projector each time. Portability is also enhanced by surprisingly robust audio for such a small projector. fit your image onto a screen you need a projection calculator tool or throw chart to tell you the image size dimensions at the correspondingTreat your eyes to the brilliance of TH671ST’s Full HD 1080p visuals, with amazing detail clarity and sharpness. Brilliant Color is a feature I’ve seen on pretty much every BenQ projector and it works differently with each model. The TH671ST’s implementation is subtle. You can barely tell a difference between the on and off setting. Ultimately, I preferred the picture with it left off.

Kong: Skull Island is a reference Blu-ray in its HD version. Here, I looked for the warm colors of the seventies as the characters visit a strange place filled with horrific CGI monsters. Not only did details like Kong’s hair pop right out, the image had lots of depth despite a flat color palette. Though much of the scenery appears shot through a filter, I could always see the finest textures and most subtle elements. Superior motion quality was again evident as objects flew with lightning speed across the screen without even a hint of blur. distance between the lens of the projector and the surface of the screen.

Vivid TV mode has a slight blue shift from neutral, which is much less of an issue than a green shift for most people, and in any case is slight enough that you're not likely to notice it without a reference image to compare it with. Those seeking to to improve contrast will want to experiment with the LumiExpert feature. LumiExpert detects the ambient light level and adjusts gamma appropriately for the lighting. You can also turn it off and adjust its setting to make the overall picture a little darker or a little brighter at any given ambient light level. We found that choosing the right setting can significantly increase contrast and the sense of three dimensionality in dark scenes. Color Preset Mode Performance. Most of the TH671ST's color modes are usable straight out of the box, even for film or video, with varying degrees of color accuracy. As with the brightest mode for most projectors, the TH671ST's Bright mode shows a slight green shift. However it is less than with most projectors, particularly those in this price range. Ventilation is generous with a quiet fan that I could barely hear at its top speed, impressive considering the bulb is 240 watts. There is a bit of light leakage from the grill and from the lens controls on top. That’s where you adjust zoom and focus with firm precise movements. Also up here are basic control buttons for power, menu navigation, and source selection.
