BenQ TH671ST: ANSI Projector with Short Throw Distance and Low Input Lag

BenQ TH671ST

If you’re looking for the middle-class entertainment projector with diverse connectivity and bright display, take a look at the BenQ TH671ST review. This projector has won an award as a gaming projector in 2019, thanks to its short throw, large screen, fast response, and blur-free motion handling. Its high brightness allows it to be used in different circumstances and the sharp color accuracy brings up a vivid and lifelike picture in any mode.

Another point to consider is the prolonged lamp life in comparison to most competitors. The projector supports multiple external devices and can be used for movie and TV watching, wireless mirroring. The speaker is quite decent for a projector and provides a stereo sound.

Design

The box of the BenQ TH671ST projector is 11.65 inches wide, 9.5 inches deep, and 4.6 inches high. This makes it look a bit coupe, more so for the curved front panel. The latter is smooth and features a small speaker grill on the left while the large red-rimmed lens window overlaps the lower edge and looks massive. The projector has five feet, some of which can be adjusted to ensure the stable tabletop position.

On the top, there’re focus and zoom controls hidden by the sliding lid, red-rimmed navigation buttons set. Connections are grouped on the back. The remote control is small and functional, with handy buttons positioning. The projector isn’t the lightest in its class weighing 5.9 lbs but still, can be mounted to wall or ceiling single-handed.

Features

The BenQ TH671ST features the DLP projection technology supported with the DMD chip. It produces a full 1080p resolution with 2 million pixels. The color palette is wide containing over billion hues and the mapping is performed in accordance with the Rec. 709 framework, with 92% correspondence. The contrast makes 10,000:1, and the brightness equals 3,000 lumens. The LumiExpert tech scans the environment and introduces the optimal amount of brightness in accordance with the chosen mode.

The short throw technology creates the sharp 100-inch image at less than 5ft, with the minimal screen size making 30 inches and the largest — 300 inches. The vertical display positioning can be adjusted up to 40% and the zooming capacity is 1.2x.

The input lag is indicated as 16.67ms in the BenQ TH671ST manual. The connectivity panel has two HDMI ports (one of which is MHL-compatible and can be used for wireless dongle), VGA, audio in and out, RS232 port, USB service, and mini-USB port.

The lamp durability for this projector is estimated as 4,000 hours of minimal lifespan and up to 15,000 hours. The integrated single speaker has 5W capacity and supports the stereo mode.

Performance

The TH671ST provides a vivid picture with bright highlights and peaks. The contrast is sharp in the dark room but tends to some smearing in shades with the increase of the ambient light. The color balance is very accurate and consistent. White colors have good saturation and are warm and solid. Blacks and grays are distinct and deep. Reds, cyans, yellow colors are spot-on, with a bit oversaturated greens.

The short throw projection system, complemented with the zoom option, lets adjust the image for any room and screen. The projector settings let choose the compensated color and bring a well-balanced picture on any background.

The motion handling is efficient and the input work is fast providing smooth gaming experience without lags and delays.
