BenQ TH671ST 1080p Short Throw Gaming Projector vs Smart Projector Projector 4K with ARC and HDR10

Picture Quality and Resolution

The Smart Projector Projector 4K with ARC and HDR10 offers a higher resolution than the BenQ TH671ST 1080p Short Throw Gaming Projector, supporting 4K content compared to the BenQ’s native Full HD 1080p resolution. While the BenQ TH671ST delivers 1080p with 3000 lumens and 92% Rec. 709 colour accuracy, the Smart Projector supports 1000 ANSI lumens with 4K resolution and HDR10, enhancing dynamic range and colour vibrancy for a more cinematic experience.

Despite the BenQ’s higher brightness rating at 3000 lumens, the Smart Projector’s 4K support and HDR10 technology make it better suited for users prioritizing ultra-high-definition visuals and richer colour contrast. The BenQ’s native Full HD resolution remains excellent for gaming and general media viewing, but for crispness and HDR support, the Smart Projector leads.

Gaming Performance and Input Lag

For gamers, the BenQ TH671ST is designed specifically with gaming in mind, featuring ultra-fast low input lag and a refresh rate tailored to match the maximum output of consoles like Xbox One X and PS4 Pro. This focus ensures smooth gameplay without motion blur, which is crucial for competitive or fast-paced gaming.

The Smart Projector does not highlight any gaming-specific optimizations such as low input lag or refresh rate matching. Its features centre on smart TV integration and multimedia streaming rather than gaming performance. Therefore, the BenQ TH671ST is the obvious choice for users seeking a gaming projector with superior response time and smooth visuals during gameplay.

Throw Distance and Screen Size

The BenQ TH671ST is a short throw projector capable of projecting a 100-inch screen from just 5 feet away, with a maximum projection size of up to 300 inches. This makes it highly flexible for rooms with limited space, allowing large images from a short distance.

The Smart Projector’s throw distance and maximum screen size details are not explicitly stated, but it emphasises intelligent auto screen adjustment features like auto focus, auto keystone correction, and smart obstacle avoidance. These features enhance ease of setup and image alignment rather than specifying throw capabilities. For users needing a short throw solution that fits tight spaces, the BenQ TH671ST’s clear 5-foot throw for 100 inches is a significant advantage.

Smart Features and User Interface

The Smart Projector excels in smart TV functionality, coming fully integrated with Google TV and supporting over 800 live channels and major streaming apps such as Netflix, YouTube, Disney+, Prime Video, and more. This all-in-one system eliminates the need for external devices or switching sources, offering a seamless streaming experience.

Additionally, it supports multi-user profiles and a child mode, allowing personalised watch lists, parental controls, and screen time limits—ideal for family use. AI-driven content recommendations and a dedicated sports tab further enhance user engagement.

In comparison, the BenQ TH671ST does not include built-in smart TV capabilities or AI-driven content features. Users relying on streaming apps would need external devices. Thus, the Smart Projector is the clear winner for those seeking a comprehensive smart home entertainment solution.

Audio Capabilities

The Smart Projector boasts Dolby Audio with dual 10W high-fidelity speakers delivering 20W total power, promising cinematic surround sound without distortion. It also supports two-way Bluetooth 5.2 for connecting to external speakers or functioning as a Bluetooth speaker itself. The inclusion of HDMI ARC/CEC simplifies integration with soundbars or AV receivers, reducing cable clutter.

The BenQ TH671ST’s feature list does not mention built-in audio specifications or advanced sound features, suggesting audio may be more basic or reliant on external speakers. For users wanting an all-in-one audio-visual experience, the Smart Projector provides a significant advantage with its enhanced sound system and connectivity options.

Connectivity and Compatibility

The BenQ TH671ST supports a broad range of input options, including HDMI and USB, making it compatible with most media players, gaming consoles, PCs, Macs, and mobile devices. This ensures flexible connectivity for various entertainment sources.

The Smart Projector also supports HDMI ARC/CEC for audio devices and includes Bluetooth 5.2 for wireless speaker connections, enhancing its multimedia versatility. However, its standout connectivity feature is the fully integrated Google TV platform, which reduces the need for external hardware.

Both projectors offer strong connectivity, but the BenQ’s emphasis on multiple input options is ideal for users who want to connect a variety of external devices. Meanwhile, the Smart Projector’s wireless and smart TV integration suits those prioritising convenience and minimal setup.

Price and Value

There is a significant price difference between the two projectors. The BenQ TH671ST is priced at C$1,049.98, while the Smart Projector is almost half that price at C$499.99. This price gap reflects their differing target audiences and feature sets.

The BenQ commands a premium for its gaming-optimised performance, higher brightness, and short throw capabilities. The Smart Projector offers modern smart features, 4K resolution, and enhanced audio at a budget-friendly price. Buyers must weigh whether the advanced gaming and brightness features of the BenQ justify the higher cost compared to the Smart Projector’s smart TV and 4K support.

Which should you buy?

Your choice depends on your primary use case and budget. If you are a serious gamer seeking ultra-smooth gameplay with low input lag, short throw projection, and high brightness, the BenQ TH671ST at C$1,049.98 is the better investment. It offers native 1080p resolution with excellent colour accuracy and is designed to handle gaming consoles with minimal motion blur.

On the other hand, if you want an affordable all-in-one home entertainment projector with 4K support, integrated Google TV, AI-driven content recommendations, multiple user profiles, and strong audio capabilities, the Smart Projector at C$499.99 is a compelling choice. It suits families and casual viewers who prioritise smart streaming features and convenience over gaming performance.

Ultimately, the BenQ TH671ST is ideal for gamers and users needing short throw projection with high brightness, while the Smart Projector fits well for those wanting smart TV integration and 4K visuals on a budget.
