BenQ TH671ST
Design and Build Quality
The BenQ TH671ST has a compact and sturdy design, which makes it easy to install in classrooms or small rooms.
Its short-throw lens allows the projector to be placed very close to the screen or wall—typically around 1.5 meters to produce a 100-inch image—minimizing shadows and glare, which is particularly beneficial in interactive learning environments.
Image Quality
Resolution: It features a Full HD 1080p resolution (1920×1080), delivering clear and detailed images suitable for presentations, videos, and gaming.
Brightness: The projector offers 3000 lumens, making it bright enough for use in well-lit classrooms without the need to darken the room completely.
Contrast Ratio: With a 10,000:1 contrast ratio, it provides decent contrast, ensuring black levels are reasonably deep and colors appear vibrant, although not as rich as higher-end models.
Color Accuracy: The projector supports Rec. 709 color standard, providing accurate color reproduction important for educational content and multimedia.
Lens and Throw Distance: The short-throw lens reduces shadows and allows for a large image in tight spaces, enhancing usability in classrooms or small meeting rooms.
Performance and Features
Input Lag: The TH671ST boasts a very low input lag (~16ms), which is excellent for gaming and interactive applications, making it versatile beyond just educational use.
Lamp Life: It offers up to 15,000 hours in SmartEco mode, which helps reduce maintenance costs and extends usability for schools and institutions.
Speakers: The built-in 10W speaker is adequate for small to medium rooms, but external audio systems are recommended for larger spaces or richer sound.
Connectivity: Multiple input options include HDMI, VGA, USB, and audio out, making it easy to connect laptops, document cameras, and other devices commonly used in classrooms.
Keystone Correction: Vertical keystone correction is supported to help adjust image distortion when the projector is not perfectly aligned. However, it lacks horizontal keystone adjustment, so placement needs to be more precise.
Ease of Use
The projector is straightforward to set up, with an intuitive menu system and remote control.
Its short throw capability simplifies installation and reduces the need for ceiling mounts or long cables. The fan noise is relatively low, minimizing distractions during lessons or presentations.
Limitations
No lens shift feature means the projector needs careful placement. While the brightness is sufficient for most classrooms, very large or brightly lit rooms might require a more powerful projector.
The absence of wireless connectivity might be a drawback for some users who prefer cable-free setups.
Value for Money
The BenQ TH671ST is competitively priced for its feature set, especially considering its short-throw capability and Full HD resolution. It offers excellent value for educational institutions that need a reliable, versatile projector without a high cost.
Summary
The BenQ TH671ST Education Projector is a solid choice for classrooms, small lecture halls, and even home entertainment. Its short-throw lens, bright image, low input lag, and robust build make it versatile for various applications.
While it has some limitations regarding advanced image adjustments and wireless features, its performance and value make it a dependable option for educators and casual users alike.
