BenQ TH671ST vs Optoma GT1080: A Head-to-Head Look at Short Throw Home Theater Projectors
Both the BenQ TH671ST and the Optoma GT1080 are compact, short throw home theater projectors designed with a focus on gaming and entertainment. Each delivers native 1080p resolution and uses DLP technology to project sharp, vibrant images, making either an excellent choice for immersive viewing experiences. However, key distinctions in their brightness, connectivity options, audio power, and smart features differentiate their appeal depending on user needs.
The BenQ TH671ST boasts a higher brightness output of 3000 lumens versus the Optoma GT1080's 2800 lumens, which can be critical for rooms with ambient light. Meanwhile, the GT1080 supports frame interpolation, enhancing motion clarity for fast-paced games and sports, a feature the BenQ model lacks. Furthermore, the TH671ST emphasizes a sleek design with a black-and-metal build, plus a superior light source power output, while the GT1080 leans on a cleaner white plastic build with a bit more powerful built-in speakers. Connectivity also varies as the Optoma includes an RS-232 port and offers VGA input alongside its other ports, whereas BenQ skips the RS-232 but includes familiar inputs like a 3.5mm audio out.
Why the BenQ TH671ST Stands Out
The BenQ TH671ST shines brightest, literally, for users seeking a punchy, vivid image in varied lighting conditions, thanks to its 3000-lumen brightness rating. This is paired with a solid 240W light source power output, which supports consistent illumination. Its short throw capability with a throw ratio between 0.5 to 1.0 allows projecting large images even in tight spaces, reaching up to a maximum screen size of 300 inches.
Another noteworthy element is its global 100-240V input voltage range, making it versatile for international use. The TH671ST also supports a combination of tabletop, ceiling, and wall mounting options that enhance installation flexibility. Despite lacking advanced smart features like built-in streaming apps or Wi-Fi, its simple and effective icon-based menu navigation and efficient remote control provide an intuitive user experience. For users valuing brightness and solid image quality without extra network features, the TH671ST is a compelling contender.
The Optoma GT1080's Strong Points
The Optoma GT1080 delivers on gaming and motion performance with its unique feature of frame interpolation, which smooths out fast-moving scenes and reduces motion blur. This can be essential for gamers who demand crisp and fluid action visuals. It also comes with a 10W speaker setup, twice as powerful as the BenQ's 5W speakers, delivering louder and clearer audio without the immediate need for external speakers.
The GT1080 also supports a basic RS-232 port for more professional AV system integration, a feature missing in the BenQ model, which makes it better suited for controlled home theater environments. Users benefit from its quick and advanced on-screen settings that allow fine-tuning the projection easily. Moreover, it includes an eco mode reducing power consumption by 30%, which can extend lamp life and lower energy bills during use.
Though the Optoma's overall brightness at 2800 lumens is slightly lower than BenQ's, it makes up for it with a balanced image sharpness enhancement level (rated 2-4), appealing to users who prioritize image clarity without oversharpening artifacts. Its build is compact and lightweight, featuring a white plastic finish that may fit white-themed home theaters better than the black BenQ.
Quick Take
The BenQ TH671ST is ideal for those who want maximum brightness and impressive light source power for vivid images in varied lighting conditions. On the flip side, the Optoma GT1080 caters well to gamers and AV enthusiasts who value smoother motion handling, stronger speaker output, and advanced input options like RS-232. Both projectors share short throw flexibility, but your choice boils down to brightness versus advanced motion and audio features.
Closing Recommendation
Choosing between the BenQ TH671ST and Optoma GT1080 depends on what matters most in your home theater setup. The TH671ST edges out with a brighter picture and slightly larger maximum screen size, perfect for rooms with ambient light challenges. Meanwhile, the GT1080 integrates thoughtful gaming-centric features and more robust audio, making it a compelling choice for a dedicated entertainment space where motion performance and sound brilliance count.
If vivid visuals in varied lighting are your priority, the BenQ TH671ST available for $899 at shop.carlofet.com is your best bet. Conversely, if you seek smoother motion handling and louder built-in audio for a slightly higher price point, the Optoma GT1080 carrying a price around $985 at Amazon stands as an excellent alternative.
Verdict
Winner: BenQ TH671ST - Superior brightness and light source power make it ideal for brighter rooms and larger screen projections.
Runner-up: Optoma GT1080 - Offers smoother motion clarity with frame interpolation and a more powerful audio system for enhanced gaming experiences.
