Price Comparison
When considering the price, the Smart Projector 4K Short Throw Mini Projectors is significantly more affordable at C$399.99 compared to the BenQ TH671ST 1080p Short Throw Gaming Projector, which retails for C$1,049.98. This price difference of C$649.99 could be a determining factor for budget-conscious consumers. While the Smart Projector offers a compelling feature set for casual use, the BenQ may justify its higher price with advanced specifications targeted towards gamers and cinephiles.
Picture Quality
The BenQ TH671ST boasts native Full HD 1080p resolution, ensuring a sharp and vibrant viewing experience. Its 92% Rec. 709 color accuracy, combined with 3000 lumens brightness, makes it ideal for both gaming and cinematic content. In contrast, the Smart Projector delivers 4K decoding support, though its final output resolution is 1080P. This means while it can handle 4K content, it ultimately displays at a lower resolution, making it less effective for high-definition viewing compared to the BenQ.
Gaming Experience
For gamers, the BenQ TH671ST is specifically designed to provide an ultra-fast low input lag, which is crucial for competitive gaming. It matches the maximum output of popular consoles like the Xbox One X and PS4 Pro, ensuring a smooth experience free from motion blur. On the other hand, the Smart Projector, while it offers versatility and portability, does not emphasize gaming performance in its specifications, making it less appealing for serious gamers looking for a responsive experience.
Throw Ratio and Projection Size
The Smart Projector features an ultra-short throw ratio of 0.8:1, allowing it to project a massive 120-inch image from just 2.1 meters away. This makes it ideal for smaller spaces where distance is a concern. In contrast, the BenQ TH671ST can project a 100-inch image from just 5 feet away, with the ability to scale up to 300 inches. While both projectors can accommodate various room sizes, the Smart Projector’s ultra-short throw is particularly advantageous for tight spaces.
Portability
Portability is a strong point for the Smart Projector, weighing in at only 1.2 kg and featuring a compact design, making it easy to carry anywhere. This means you can easily take it to a friend's house or set it up in the backyard for outdoor movie nights. The BenQ TH671ST, while still compact, does not emphasize portability in its design, making it less convenient for on-the-go use. For those who value mobility, the Smart Projector stands out as the better option.
Connectivity Options
The BenQ TH671ST offers flexible connectivity with support for a variety of media players, gaming consoles, PCs, Macs, and mobile devices through HDMI and USB inputs. This makes it versatile for various entertainment setups. The Smart Projector also supports streaming through its bundled Google TV Stick, allowing access to over 10,000 apps, including popular services like Netflix and Disney+. While both projectors provide good connectivity, the BenQ’s broader compatibility with gaming equipment could be more appealing for dedicated gamers.
Unique Features
The Smart Projector comes packed with features such as AI auto focus, keystone correction, auto obstacle avoidance, and an adjustable stand that allows for flexible projection angles. These technologies enhance usability and adaptability in different environments. In contrast, the BenQ TH671ST is recognized for its award-winning gaming capabilities, which may appeal more to dedicated gamers than casual viewers. While both projectors have unique selling points, the Smart Projector's features cater to versatile usage scenarios.
Which should you buy?
Deciding between the Smart Projector 4K Short Throw Mini Projectors and the BenQ TH671ST 1080p Short Throw Gaming Projector ultimately depends on your priorities. If budget, portability, and versatility are your main concerns, the Smart Projector is a strong choice at C$399.99. However, if you seek superior picture quality, gaming performance, and a larger projection size, the BenQ at C$1,049.98 justifies its price with features tailored for serious gamers and cinephiles. Consider what matters most to you—whether it's casual viewing or a premium gaming experience—before making your decision.
