The BenQ TH685P is a technological marvel. Its 1080p resolution enhanced by 4K readiness makes it a go-to projector for high-definition content lovers. In our testing, the unit’s impressive brightness of 3500 ANSI lumens made it an ideal choice for rooms with ambient light. The image quality was striking, with vibrant colors supported by the 95% Rec. 709 coverage, making movie and gaming scenes come to life.

We also found the low input lag of 8.3ms at 1080p/120Hz to be a game-changer for gamers. With game mode and game sound mode, we had an immersive gaming experience with detailed audio from the integrated 5W treVolo speaker. The lack of VGA-in or Monitor-Out compared to the TH685 was slightly disappointing, but the overall performance of the TH685P makes it a worthy investment.

The BenQ HT2050A left us impressed with its superior picture quality and high native contrast ratio. The projector’s 2200 ANSI lumens may not be as bright as the TH685P, but we found it adequate in a controlled lighting environment. The picture quality, with its 96% Rec. 709 coverage, was crisp and immersive, making it an excellent choice for movie enthusiasts.

BenQ HT2050A vs. TH685P Features Comparison

Build and Design

Both the TH685P and the HT2050A are impressively built. With a compact and lightweight design, the TH685P weighs just 6.15 lb and measures 12.2 x 4.3 x 8.8 inches, whereas the HT2050A is slightly bulkier, at 6.6 lb and 15 x 4.8 x 10.9 inches. We found that the smaller footprint of the TH685P makes it a better fit for smaller spaces or for those who need a portable projector. You might be interested in our full BenQ TH685P review.

While both projectors feature a 1080p native resolution and 16:9 aspect ratio, there are significant differences in their display capabilities. The TH685P, with its 3500 ANSI lumens, outperforms the HT2050A’s 2200 ANSI lumens in terms of brightness, making it a superior choice for environments with ambient light. The higher brightness rating was evident during our tests in a lit room, where the TH685P was able to produce a clear and bright image while the HT2050A struggled a bit.

However, the HT2050A scores higher on contrast ratio, providing deeper blacks and more vibrant colors, thanks to its 15,000:1 FOFO contrast ratio compared to the 10,000:1 offered by the TH685P. Both projectors promise Rec.709 coverage, with the HT2050A at 96% and the TH685P slightly lower at 95%. Read our in-depth BenQ HT2050A review.

Performance is where the comparison of BenQ TH685P vs HT2050A gets interesting. The TH685P is geared towards gaming with a low input lag of 8.3ms at 1080p@120Hz, 16.7 ms at 1080p@60Hz, and 33.4 ms at 4K@60Hz. This is excellent for games, resulting in smooth gameplay without noticeable delay. On the other hand, the HT2050A has a lag time of 16 ms at 1080p@60Hz, which is still decent for casual gaming.

Our gaming experience on the TH685P was superb, with no noticeable lag. It also handles downscaling 4K inputs to 1080p impressively, a feature the HT2050A lacks.


Both projectors feature two HDMI inputs, with the TH685P having the edge with HDMI 2.0b/HDCP2.2 support, which can handle higher bandwidth content like 4K@60Hz. The HT2050A, on the other hand, only supports HDMI 1.4a/HDCP1.4.

The TH685P, however, does not feature a VGA input, which the HT2050A does, limiting some connectivity options for older devices.

The built-in audio systems of the two projectors are quite different. The TH685P has a single 5W chamber speaker integrated with a treVolo equalizer for enhanced audio, while the HT2050A comes with a more powerful 10W chamber. Both speakers are acceptable for casual viewing but for the best audio experience, we recommend using an external sound system.

Customer Reviews

We’ve noticed that customers of both the BenQ TH685P and HT2050A are quite satisfied with their purchases. Many were impressed with the image quality and overall performance of both projectors. For the TH685P, customers praised its brightness, color accuracy, and gaming capabilities. However, some customers wished for a smaller throw distance as they had to either move the projector back or get a larger screen.

HT2050A customers were pleased with its image quality and performance, too. Some customers did mention issues with sound output over HDMI.


In conclusion, while the selection between the BenQ TH685P and HT2050A inevitably boils down to your individual needs, we firmly believe the TH685P holds a slight edge. It shines as an ultra-bright projector that not only excels in gaming but also effortlessly handles 4K content. The HT2050A, on the other hand, stands out with its exceptional image quality, deep blacks, and superior contrast ratio, but it doesn’t offer the same versatility that the TH685P brings to the table.
