Or if you’re looking to host a movie night outdoors, you may want to consider one of BenQ’s portable smart projector models, such as the 1080p HD resolution BenQ GV series. This Bluetooth projector has IPX dust and splash resistance and comes with built-in speakers that provide surprisingly powerful audio output. If your selected projector has a Zoom Lens then the projector's Throw Distance or Image Size can be finely adjusted by moving the

measurement between the front of the projector lens and the surface of your wall or screen. Using the Zoom Range SliderAs 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. Pro 1) Affordable Projectors With HD and 4K: BenQ offers some 4K UHD home projectors in a price range usually reserved for lower-resolution XGA projectors. They even sell a 1080p portable projector with 2.1 channel Bluetooth-enabled 10W speakers built-in. By the way, it’s always good to compare 4K vs 1080p projectors, so you know which resolution works best for you. 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. As mentioned before, my personal projector is about three years old and has similar measurables to the BenQ TH671ST, however I noticed that the BenQ was brighter, more detailed and smoother than mine, which could very well be due to the 16.67ms low input lag and microsecond DMD response time.

Short throw projection refers to a distance between 3 to 8 feet away from projector to screen, so therefore a short throw projector is one which can be positioned within that distance from the area you have designated as your screen. Ultra-short throw projection refers to a distance between 0 to 4 feet away from projector to screen and, again, projectors deemed ultra-short throw are devices which work within that measurement. There are also 'long throw' projectors, which have been specifically designed to provide very large imagesfrom a position in the centre of the ceiling in a large room.On portable projectors, battery life is an additional factor that may influence how long the item lasts. Most portable models use lithium-ion batteries rated for between 500 and 2,000 charge cycles.

lumens of high brightness let you watch in relatively bright settings or even with lights on. Perfect for meeting rooms. Pro 3) Full-featured Gaming Projectors: BenQ is one of a few brands that offer explicitly “gaming-focused” projectors. Compared to traditional projectors, these gaming projectors specialize in minimal input lag time, with ultra-low input latency and a high enough refresh rate to enjoy fast-paced gaming. BenQ stands out for selling a top-notched 4K projector for gaming that combines excellent picture quality with very low input lag. 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. 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. 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.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. distance between the lens of the projector and the surface of the screen. On the graphical representation of a screen in the middle of the Factors that affect how long a projector will last include frequency of use, environmental conditions, and how it’s maintained. Fortunately, most modern BenQ DLP projectors use low-maintenance sealed mirror assemblies and long-life LED or laser light sources. 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
