Cinema and Sport modes, as already mentioned, both deliver good color accuracy by default, and the best accuracy of any of the modes. Game mode straight out of the box is a little cooler than the Cinema and Sport modes, with a whiter white and skin tones that look a little too porcelain in some images. Chris' passion for audio began when he took up playing the bassoon at age 12. During his third year at the New England Conservatory of Music, he won a position with the West Point Band where he served for 26 years as principal bassoonist. He retired from the Army in 2013 and is now writing full time and performing as a freelance musician in Central Florida. The TH671ST’s menu system is just like the one I’ve encountered on many previous BenQ projectors. If you want to avoid the detailed settings, just choose the Basic version which only gives you, well, the basics like input selection, picture modes, and the like. Tweakers and videophiles will want to choose Advanced for full access to all the calibration controls and features. 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.

Countering the trapezoid effect when the projector must be placed off-center, such as simple placement on top of a table, vertical keystone adjusts the image for a professionally squared image. Keystone correction makes it simple to project ideally aligned images from a variety of locations. 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. Zoom Lens Light Loss. The 1.2x zoom isn't large enough to curtail brightness significantly at the telephoto end of the lens. You can safely ignore the potential light loss when choosing how far to put the projector from the screen. With video optimized settings, the TH671ST can light up a 120-inch 1.2-gain screen in moderately bright ambient light using full power, or a 100-inch 1.2-gain screen in Economic mode. And the LumiExpert feature can adjust gamma automatically for the current ambient light level, with a dedicated menu button on the remote so you can easily tweak its effect to taste. Brightness is another key feature. We measured the TH671ST at a little over 2,600 ANSI lumens, which is enough to light up a 130-inch 1.0-gain screen in moderately bright ambient light. Even its video optimized setting, at a measured 1,887 lumens, is bright enough at the same light level for a 110-inch 1.0-gain screen or a 120-inch 1.2 gain screen.Low Lamp Mode. Compared with the full power mode, Economic mode reduces brightness by about 36%. Two other settings, SmartEco and LampSave, are dynamic power modes that are intended to lenghthen lamp life by adjusting the power level based on scene content. With a standard 100% white image, we measured SmartEco at the same brightness as Normal power mode. LampSave peaked at 1,767 ANSI lumens in Bright mode, just a touch brighter than Economic mode. BenQ says there is no noticeable effect on the image with these modes, nor did we observe any. Light Mode contains the four lamp levels. Normal is brightest followed by Eco which cuts output by about 35%. SmartEco throttles brightness and roughly doubles static contrast with occasionally visible image pumping. LampSave also varies output and extends lamp life to a claimed 15,000 hours. the graphical representation of a projector in the middle of the calculator, you will see dimension lines that will tell you the Throw Distance 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.

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. Brightness Uniformity. The test unit's brightness uniformity is 63%. Somewhat surprisingly—because short throw projectors tend to have problems maintaining uniform brightness—this is actually a better than typical result for standard throw home theater projectors in this price range.As an avid movie lover, Chris was unable to turn away the 50-inch Samsung DLP TV that arrived at his door one day, thus launching him irrevocably into an obsession with home theater. Dissatisfied with the image quality of his new acquisition, Chris trained with the Imaging Science Foundation in 2006 and became a professional display calibrator. His ultimate theater desires were realized when he completed construction of a dedicated cinema/listening room in his home. Chris is extremely fortunate that his need for quality audio and video is shared and supported by his wife of over 25 years. Throw Distance. Unlike most short throw projectors, the TH671ST offers a zoom lens, which adds flexibility for positioning the projector to help make setup easy. Simply place the projector at approximately the right distance from the screen, and then fit the image to the screen by adjusting the 1.2x zoom, rather than moving the projector. The range for a 110-inch 16:9 image is roughly 5.5 to 6.7 feet. The BenQ TH671ST Projection Calculator will let you find the throw distance range for the image size you want. 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. watt speaker delivers surprisingly robust audio for such a small projector, with enough volume to fill a large family room; five sound mode presets plus User mode.

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. With default settings, Sport mode has a slight yellow-green shift, but it is easy to tweak for suitably neutral color, and without affecting either ANSI brightness or the brighter shades of yellow. BenQ's Color Management settings let you adjust hue, saturation, and gain individually for all six primary (red, green, blue) and secondary (cyan, yellow magenta) colors. Prices valid in stores (all including VAT) until close of business on 29th November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.) TH671ST maximises thrills in minimal space, requiring as little as 1.5m to project stunning 100” pictures. The shortened throw enables carefree enjoyment without space constraints or setup hassles.

Setting Up the BenQ TH671ST

With an outstanding brightness figure of 3000 ANSI Lumens, the TH671ST suits all types of lighting conditions. Even during daylight conditions with curtains or blinds open, the TH670 produces a watchable and detailed picture - perfect for gaming on a weekend afternoon. For optimal performance, BenQ’s LumiExpert technology detects lighting conditions and automatically adjusts the brightness to suit.

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.The perfect resolution for Blu-ray and gaming, 1080p Full HD gives noticeably more detail than standard HD resolution. Suddenly, you'll see texture in the grass on the pitch, subtle detail in wildlife documentaries and a whole new depth of image. The larger the screen and the closer you sit the greater the benefit, making 1080p more impressive on a projector at home compared to a TV. Perfectly Long Lasting Picture Quality with DLP Projection Technology Digital Light Processing (DLP), awarded 2015 Academy Award of Merit (Oscar statuette), is the leading projection technology used in 90% of world’s digital cinemas and 100% of IMAX theaters. With DLP dominating the worldwide projector market with over 50% share, BenQ is today the #1 bestselling DLP. 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. All the important stuff is in the Advanced sub-menu. There are nine gamma presets which offer fine control and excellent accuracy. I chose 2.3 for its slightly better mid-tone contrast and color saturation. Color Temperature comes in four flavors, all of which are adjustable with gain and bias sliders; Normal comes closest to D65. You also get a color management system with hue, saturation, and gain (luminance) sliders for all six colors. represents the diagonal distance between the top right corner of your image (screen) and the bottom left corner of your image (screen).
