Price Comparison
The Mini Smart 4K Projector is priced at £132.58, making it significantly more affordable than the BenQ TH575i, which retails for £479.00. This substantial price difference of £346.42 positions the Mini Smart 4K Projector as an attractive choice for budget-conscious consumers who still desire quality performance. While the BenQ offers more advanced features, the initial investment for the Mini Smart 4K Projector is appealing for those seeking an entry-level option in the 4K projector market.
Picture Quality
In terms of picture quality, the Mini Smart 4K Projector supports native 1080P resolution and can display content up to 4K, boasting a brightness of 1000 ANSI lumens. In contrast, the BenQ TH575i provides a brighter experience with 3,800 lumens, enabling it to excel in well-lit environments. The higher brightness of the BenQ translates to clearer visuals on a large 120-inch screen, making it a better choice for daytime viewing or larger rooms. Thus, if picture clarity and brightness are priorities, the BenQ TH575i offers a significant advantage.
Smart Features
The Mini Smart 4K Projector includes the Smart Whale OS, which comes pre-loaded with popular streaming apps like YouTube and Prime Video, allowing instant access without additional hardware. It also supports numerous downloadable apps, enhancing its functionality as a streaming hub. Meanwhile, the BenQ TH575i includes a licensed Google TV dongle, facilitating access to popular streaming services such as Netflix, YouTube, and Disney+. Both projectors provide excellent smart features, but the choice may hinge on whether users prefer an integrated system (Mini Smart 4K) or a plug-and-play solution (BenQ).
Gaming Performance
Gaming enthusiasts may favour the BenQ TH575i due to its ultra-smooth 16.7ms low input lag, ensuring minimal delay during fast-paced gaming sessions. This feature is particularly beneficial for competitive gamers looking for an edge in responsiveness. The Mini Smart 4K Projector does not specify any gaming performance metrics, which may indicate it's less optimised for this purpose. Therefore, for gamers, the superior input lag of the BenQ makes it the clear winner for a seamless gaming experience.
Setup and Installation
When it comes to setup and installation, the BenQ TH575i is designed for flexibility with its 1.1x optical zoom and Auto Vertical Keystone correction, enabling an easy and straightforward placement process. This feature helps achieve a perfectly squared image without the hassle of complicated adjustments. The Mini Smart 4K Projector, while offering auto-correction features, does not provide specific details on zoom capabilities. For users who value a quick and easy setup, the BenQ TH575i may be more suitable.
Audio Quality
Audio quality is an essential aspect to consider, and here the Mini Smart 4K Projector stands out with its HiFi stereo speakers and unique sealed core technology, which significantly reduces noise by up to 80%. This feature allows for an immersive audio experience without the need for external speakers. The BenQ TH575i does not mention built-in audio capabilities, implying that a separate sound system may be necessary for optimal audio enjoyment. Therefore, for those prioritising sound quality, the Mini Smart 4K Projector may be the better option.
Brightness and Environment Suitability
The brightness level of a projector can greatly affect its performance in various environments. The Mini Smart 4K Projector has a brightness of 1000 ANSI lumens, suitable for darker settings, whereas the BenQ TH575i boasts a remarkable 3,800 lumens, making it ideal for brighter rooms. This means that the BenQ can deliver vibrant visuals even with the lights on, making it a superior choice for daytime usage or larger spaces. If the intended use is in a well-lit environment, the BenQ TH575i is undoubtedly the better option.
Which should you buy?
Ultimately, the choice between the Mini Smart 4K Projector and the BenQ TH575i hinges on individual needs and budget. The Mini Smart 4K Projector is a compelling option for those seeking an affordable, feature-rich projector suitable for streaming and casual use, especially in darker environments. Conversely, the BenQ TH575i excels in brightness, gaming performance, and setup ease, making it ideal for users who prioritise high-quality visuals and versatile functionality, particularly in well-lit settings.
