BenQ 1080p DLP Home Theater Short Throw Projector (TH671ST), 3000 Lumens, Low Input Lag for Gaming, Ambient Light Sensor

Product Information

away from the screen or wall, the image will get bigger, and as you push the projector closer to the screen or wall the image will be smaller. To properly 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. 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. 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. lumens of high brightness let you watch in relatively bright settings or even with lights on. Perfect for meeting rooms.

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. Brightness. The BenQ TH671ST test unit came in at 2,638 ANSI lumens in our tests, a solid 86% of its 3,000 ANSI lumen rating. With the 1.2x zoom lens at its widest angle setting, our measurements for Normal and Economic power modes are as follows: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. 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. 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. Lens offset. The lens offset for the TH671ST is designed for placement on a low table, with the bottom edge of the image falling somewhere between the lens centerline and up to 5% of the image height above it. For example, with a 100-inch high image the bottom edge would be anywhere between even with the lens centerline and 5 inches above it. The bottom edge of the image on our test unit was about 4% of the image height above the centerline, which is within typical sample-to-sample variation. 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.

If your selected projector has a Zoom Lens then the projector's Throw Distance or Image Size can be finely adjusted by moving the calculator, you will see dimension lines that will tell you the height, width, and diagonal measurements of your image. Calculating a Throw Distance when you know the IMAGE SIZE 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.

Calculating an Image Size when you know the THROW DISTANCE

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.

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. 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 The BenQ TH671ST offers the advantage of Keystone Correction. This handy feature offers great benefits when installing. With the ability to digitally shift the image by +/- 40 degrees in the vertical plain, the TH671ST can be fitted in more awkward locations and enables a wider choice of screen options.Prices valid in stores (all including VAT) until close of business on 29th November 2023.

The Zoom Range slider in the calculator will help you calculate the changes made by a Zoom Lens.

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. 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. Fast Mode is the input lag control and you can leave it on all the time if you wish. It lowers latency and doesn’t affect normal video content in any visible way. It will certainly improve the gaming experience though. represents the diagonal distance between the top right corner of your image (screen) and the bottom left corner of your image (screen).
