Portable Smart vs Gaming Projectors: Finding Your Perfect Home Theater Match

If you're shopping for a projector in 2024, you've probably noticed something interesting: the market has split into two distinct camps. On one side, we have portable smart projectors like the Aurzen BOOM 3, promising all-in-one convenience with streaming apps and powerful speakers built right in. On the other, dedicated gaming projectors like the BenQ TH685P focus purely on performance, delivering the brightness and lightning-fast response times that serious gamers demand.

Having tested both approaches over the past few years, I can tell you that choosing between them isn't just about specs on paper – it's about understanding how you actually plan to use your projector. Let me walk you through everything you need to know to make the right choice.

Understanding Modern Projector Categories

The projector world has evolved dramatically since the early 2020s. Traditional projectors required separate streaming devices, external speakers, and often complex setup procedures. The Aurzen BOOM 3, released in 2023, represents the new wave of "smart projectors" that aim to be complete entertainment systems in a single box. Meanwhile, the BenQ TH685P, launched in 2022, exemplifies the gaming-focused approach that prioritizes raw performance above all else.

When evaluating any projector, you need to consider several key factors: brightness (measured in ANSI lumens – essentially how well the image cuts through ambient light), input lag (the delay between pressing a controller button and seeing the action on screen), audio quality, smart features, and overall value for your specific needs.

Performance Deep Dive: Where Each Projector Shines

Brightness: The Foundation of Image Quality

Here's where the fundamental difference between these approaches becomes crystal clear. The BenQ TH685P pumps out an impressive 3,500 ANSI lumens, while the Aurzen BOOM 3 manages 500 ANSI lumens. That's a seven-fold difference, and it translates to dramatically different use cases.

I've used both projectors extensively, and the brightness gap is immediately apparent. The BenQ TH685P can handle a living room with some ambient light – you can watch a movie on a Saturday afternoon without turning your space into a cave. The Aurzen BOOM 3, by contrast, really needs dim or dark conditions to shine. Its LED-based lighting system is more energy-efficient and generates less heat, but it simply can't compete in bright environments.

This brightness difference also affects screen size capabilities. While both projectors can technically project large images, the BenQ TH685P maintains good image quality at 200-300 inch diagonal screens, whereas the Aurzen BOOM 3 is optimized for 60-100 inch displays. Beyond that range, the image starts to look washed out and dim.

Gaming Performance: Speed Matters

If gaming is a priority, the BenQ TH685P isn't just better – it's in a completely different league. Its 8.3ms input lag at 1080p/120Hz means virtually no delay between your controller input and the on-screen action. For comparison, most TVs hover around 20-30ms, and the Aurzen BOOM 3 doesn't even specify its gaming performance metrics.

Input lag becomes crucial in fast-paced games where split-second reactions matter. I've played competitive shooters on both projectors, and while the Aurzen BOOM 3 is perfectly fine for casual gaming sessions with friends, the BenQ TH685P feels noticeably more responsive during intense multiplayer matches.

The BenQ TH685P also includes a dedicated Game Mode that enhances visibility in dark scenes – a feature that can give you a real advantage in games where enemies might be lurking in shadows. The 120Hz refresh rate support means smoother motion in supported games, though you'll need a compatible console or PC to take full advantage.

Audio: The Unexpected Game Changer

This is where the Aurzen BOOM 3 absolutely dominates. Its 36W audio system with four speakers arranged in a 2.2-channel configuration delivers sound that rivals dedicated soundbars. The inclusion of DSP (Digital Signal Processing) technology and 3D Dolby Audio creates an immersive soundstage that fills a room.

I've been genuinely impressed by the bass response from such a compact device. Movies with explosive action sequences have real impact, and dialogue remains clear and centered. The bidirectional Bluetooth 5.2 capability means you can even use the Aurzen BOOM 3 as a standalone Bluetooth speaker when you're not projecting.

The BenQ TH685P's 5W mono speaker, by comparison, is clearly an afterthought. It's adequate for basic audio feedback, but you'll definitely want external speakers or a soundbar for any serious viewing. This isn't necessarily a flaw – many dedicated projector enthusiasts prefer to choose their own audio solution – but it does add to the total system cost and complexity.

Smart Features: Convenience vs Control

The smart feature divide perfectly illustrates the philosophical difference between these projectors. The Aurzen BOOM 3 runs a proprietary Smart TV OS with officially licensed apps for Netflix, Prime Video, and YouTube. Setup is essentially plug-and-play: connect to WiFi, log into your streaming accounts, and start watching.

Having used countless streaming devices over the years, I appreciate this simplicity. There's no juggling of multiple remotes, no cable management for HDMI connections, and no worrying about whether your streaming stick supports the latest app updates. The Aurzen BOOM 3's AI-powered auto-focus and 6D keystone correction (which automatically adjusts the image shape when projecting at an angle) means you can literally point it at a wall and have a properly aligned image in seconds.

The BenQ TH685P takes the opposite approach, offering no smart features whatsoever. You'll need to connect external devices like streaming sticks, gaming consoles, or laptops via HDMI. This gives you complete control over your content sources and ensures you're not locked into any particular ecosystem, but it requires more planning and equipment.

Real-World Use Cases: Where Each Projector Excels

The Aurzen BOOM 3's Sweet Spot

I've found the Aurzen BOOM 3 excels in scenarios where convenience and portability matter most. In a bedroom setup, its compact size and excellent audio eliminate the need for additional equipment. The automated focusing and keystone correction make it perfect for temporary setups – I've taken it to friends' houses for outdoor movie nights where we simply pointed it at a garage door and had great results.

For apartment dwellers or anyone with space constraints, the Aurzen BOOM 3's all-in-one approach is compelling. You get a complete entertainment system that can easily move between rooms or pack away when not needed. The built-in streaming apps mean you're never hunting for the right remote or dealing with input switching.

The portability factor shouldn't be underestimated. At 5.5 pounds with everything built in, the Aurzen BOOM 3 is genuinely portable in ways that traditional projector setups aren't. I've used it for backyard gatherings where running multiple cables wasn't practical, and its battery-free operation (it needs AC power) is still more convenient than coordinating multiple devices.

The BenQ TH685P's Domain

The BenQ TH685P shines in more permanent, performance-focused installations. If you're setting up a dedicated home theater room or gaming cave, its superior brightness and gaming optimization become major advantages. The ability to use it in rooms with some ambient light opens up placement options that the Aurzen BOOM 3 simply can't match.

For serious gamers, the BenQ TH685P's low input lag and 120Hz support can provide a genuine competitive edge. I've noticed the difference is most apparent in fast-paced games where precise timing matters. The larger screen sizes it can effectively support also create a more immersive gaming experience – there's something magical about playing games on a 200+ inch display.

The BenQ TH685P also makes more sense if you already have or plan to invest in a quality audio system. Its minimal built-in audio means you're not paying for speakers you won't use, and you can pair it with whatever sound system matches your preferences and budget.

Technical Innovations and Market Evolution

Both projectors represent significant advances over earlier generations. The Aurzen BOOM 3's AI-powered auto-focus system uses nine directional gyroscopes to continuously monitor and adjust focus – a level of automation that would have been unthinkable in budget projectors just a few years ago. Its obstacle avoidance feature can even detect when objects are blocking part of the projection area and automatically adjust the image.

The BenQ TH685P benefits from BenQ's decades of projector experience, implementing DLP (Digital Light Processing) technology that delivers sharp images with minimal motion blur. Its 95% coverage of the Rec.709 color space ensures accurate color reproduction that meets professional standards.

Since these projectors launched, we've seen continued improvements in LED efficiency, smart TV platforms, and automated adjustment systems. The projector market in 2024 offers capabilities that were reserved for premium models just a couple of years ago.

Value Analysis: What You Get for Your Money

At the time of writing, these projectors occupy very different price tiers, with the Aurzen BOOM 3 positioned as an affordable all-in-one solution and the BenQ TH685P commanding a premium for its gaming performance and brightness.

The Aurzen BOOM 3 delivers exceptional value if you prioritize convenience and integrated features. When you factor in the cost of external speakers, streaming devices, and the simplicity of setup, it becomes an attractive package for many users. Its main limitation is the brightness ceiling – you're committed to dim-room viewing.

The BenQ TH685P costs significantly more but delivers proportionally better performance in key areas. The brightness advantage alone makes it suitable for a wider range of environments and screen sizes. For dedicated gaming setups, the low input lag and gaming optimizations can justify the premium.

Making the Right Choice for Your Situation

After extensive testing with both projectors, here's my honest assessment of who should choose which option.

Choose the Aurzen BOOM 3 if you want the simplest possible path to big-screen entertainment. It's perfect for renters who can't install permanent audio systems, students in dorm rooms, or anyone who values convenience over absolute performance. The excellent built-in audio means you'll get a satisfying experience right out of the box, and the smart features eliminate the need for additional devices.

The BenQ TH685P makes sense if you're serious about gaming performance or need bright projection for well-lit rooms. It's the better choice for dedicated home theater installations where you have the flexibility to add external audio and streaming devices. The superior brightness and larger screen capabilities make it worth the premium for users who prioritize visual performance.

For most casual users, I lean toward recommending the Aurzen BOOM 3 because its limitations are more easily worked around than its competitor's. You can always dim the lights for better image quality, but you can't easily add 3,000 lumens to a dimmer projector.

However, if gaming is your primary use case, the BenQ TH685P is worth the extra investment. The input lag difference is significant enough to impact your gaming experience, and the brighter output means you won't have to choose between natural lighting and good image quality.

The Bottom Line

These projectors represent two valid but different approaches to home projection. The Aurzen BOOM 3 prioritizes user-friendly features and all-in-one convenience, while the BenQ TH685P focuses on maximum performance and flexibility. Your choice should align with how you actually plan to use your projector – not just your aspirational home theater dreams.

Both projectors deliver on their respective promises, and both have evolved the projector market in meaningful ways. The key is being honest about your priorities, your space, and your viewing habits. Whether you choose convenience or performance, you'll be getting a projector that represents the best of current technology in its category.
