BenQ TH671ST 1080p Short Throw Gaming Projector, 3000 Lumens, Low Input Lag for Gaming, Built-in 5W Speaker

Product Information

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. 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. 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. As with virtually all inexpensive home theater projectors we've tested, the brightness variation is easy to see with a 100% white or light colored image. With the projector sitting on a table, brightness is highest at the bottom center of the image, and gradually falls going up and to either side, making the upper left and right corners the dimmest. Those who are particularly sensitive to brightness variations may find this unacceptable. However the difference is hard to see with any image that breaks up the field of view.

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. 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. lumens of high brightness let you watch in relatively bright settings or even with lights on. Perfect for meeting rooms. To determine the Image Size (screen size) enter a distance measurement number in the Throw Distance value box and hit the EnterVideo Optimized Lumens. Both the Cinema and Sport modes are good starting points for optimizing settings for video. Both deliver color that's well within a realistic looking range and close enough to accurate so you wouldn't know that any color is off without a reference image to compare to. However, Sport mode delivers a higher ANSI lumen measurement and brighter shades of yellow, which prove to be more accurate when comparing with a reference image. 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. 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. 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.

Note that we saw an occasional skipped frame when watching movies at 24 frames per second (fps)—though not at 60 fps. Skipped frames are usually visible as a random, judder-like jump (only bigger) in the middle of a camera pan, or in the movement of an on-screen object when the camera is fixed. It seemed to happen more frequently with LumiExpert on, however, these skips were rare and not reliably repeatable. BenQ has been looking into the issue to determine if it's isolated to our set-up or something that might require a firmware correction. 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. Given its design parameters, there is really nothing to complain about here. The BenQ TH671ST delivers accurate Rec.709 color, superb clarity, bright imagery, and low input lag just as promised. Though 3D isn’t a big draw for consumers any longer, it still looks great on this projector. With a compact chassis and short-throw lens, it can be set up just about anywhere. It’s small enough to be portable but that also makes it ideal for smaller media rooms where one might not have 10 or 15 feet of depth to throw a 100” image. The TH671ST can do it from just five feet away, on a coffee table, or hung from the ceiling. 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.
