BenQ TH671ST vs BenQ HT2150ST: A Tale of Two Home Theater Gaming Projectors

When it comes to short-throw projectors tailored for home theater and gaming, the BenQ TH671ST (2024) and the BenQ HT2150ST (2016) both stand out as compelling choices. Each delivers a native 1080p resolution and harnesses DLP projection technology with 0.65" chips, targeting immersive visuals in compact setups. However, these models diverge significantly in brightness, contrast performance, connectivity, and additional features, reflecting their distinct design eras and intended user priorities. The TH671ST boasts a modern, sleek black build with a powerful 3000 lumens brightness and longer lamp life, while the HT2150ST offers superior contrast ratios, a more extensive color gamut, and advanced image calibration capabilities tailored more towards cinematic aficionados. Both projectors also cater to multiple projection alignment types including front, rear, ceiling, and tabletop configurations, offering versatile placement options.

BenQ TH671ST: Lighting Up Bright Rooms and Gaming Arenas

The BenQ TH671ST shines brightest; quite literally; with its 3000 lumens peak brightness, making it an ideal pick for spaces with ambient light where visibility matters most. It supports an impressive 10,000:1 contrast ratio coupled with a neutral color temperature that delivers balanced hues without warmth or cool bias, appealing to users who prefer natural visuals. The lens system offers a flexible optical zoom range of 1.2x-1.5x, allowing for precision in image sizing up to a massive 300-inch screen.

Connectivity is robust, featuring two HDMI 1.4 ports and two USB ports (USB-A and USB-Mini B), ensuring compatibility with multiple devices such as gaming consoles and streaming sticks simultaneously. The projector houses a lamp that lasts a whopping 10,000 hours in eco mode, which extends to 4,000 hours in normal mode; underscoring its suitability for long gaming sessions or marathon movie nights.

Physically, it is noticeably lighter and more compact (6 lbs and roughly 11.65"W x 8.82"D x 4.72"H) than its predecessor, sporting an all-black facade that meshes seamlessly with dark rooms or gaming setups. Its automated vertical keystone correction eliminates much hassle during installation, while a moderately quiet fan noise of 33 dB maintains a tolerable sound environment.

BenQ HT2150ST: A Veteran's Color Precision and Cinematic Excellence

While the HT2150ST doesn't have the brightness punch of the TH671ST, it excels in delivering a richer video experience, boasting a higher contrast ratio of 15,000:1 and an astonishing dynamic contrast ratio that peaks between 50,000:1 and 200,000:1. This translates to deeper blacks and more detailed shadows; crucial for home theater enthusiasts seeking cinema-grade picture fidelity.

The color gamut coverage at 96% surpasses the TH671ST, and the projector supports advanced imaging tweaks such as auto color correction, skin tone correction, black level enhancement, and white balance controls. These features empower users who demand image accuracy and vibrant cinematic visuals.

Its sonic performance is also noteworthy, featuring a powerful 20W mono speaker far louder than the TH671ST's 5W output, and a quieter cooling system with a 29 dB noise level, ideal for low-distraction viewing.

Moreover, the HT2150ST accommodates smaller spaces via a shorter minimum throw distance of 3.5 feet compared to the TH671ST's 4.9 feet. It also caters to a broader array of input needs with additional ports like AV composite input, 12V trigger port, and RS-232 port, elevating its integration potential within elaborate home cinema setups.

Quick Take

The BenQ TH671ST edges forward with higher brightness, improved lamp longevity, and a sleek, compact profile, perfect for well-lit rooms and gaming setups. Meanwhile, the BenQ HT2150ST remains a go-to for cinephiles who value superior contrast, richer colors, and quieter performance in controlled lighting environments.

Closing Recommendation

Choosing between these two projectors hinges on your priorities: if your environment demands brighter images and longer lamp life, the BenQ TH671ST delivers a compelling and modern package. Conversely, for immersive movie nights with striking contrast and advanced color tuning, the seasoned BenQ HT2150ST stands strong as a classic contender.

Verdict

  • Winner: BenQ TH671ST - Its superior brightness, extended lamp life, and modern connectivity make it ideal for versatile use in both bright and dark settings.
  • Runner-up: BenQ HT2150ST - Offers exceptional contrast, color fidelity, and quieter operation, perfect for dedicated home theater enthusiasts who prioritize image precision.
