Smart vs Gaming Projectors: Choosing Between Convenience and Performance

When shopping for a projector in 2025, you're essentially choosing between two very different philosophies: the all-in-one convenience of smart projectors or the specialized performance of gaming-focused models. The HAPPRUN Google TV Smart Projector and BenQ TH685P Gaming Projector represent these approaches perfectly, each excelling in their intended use while making significant trade-offs elsewhere.

Understanding Modern Projector Categories

The projector market has evolved dramatically since these models launched. The HAPPRUN arrived in 2024 as part of the latest wave of budget smart projectors that integrate streaming platforms directly into the device. Meanwhile, the BenQ TH685P debuted in 2022 during the gaming projector boom, when manufacturers began prioritizing ultra-low input lag and high refresh rates to compete with gaming monitors.

This timing matters because it reflects broader industry trends. Smart projectors have become increasingly sophisticated, with newer models like the HAPPRUN featuring official Netflix licensing and advanced wireless connectivity that wasn't available in earlier budget models. Gaming projectors, led by devices like the BenQ TH685P, have pushed input lag down from the 50-100ms range that was common just a few years ago to gaming-monitor levels of responsiveness.

The fundamental question you need to answer is whether you want a projector that handles everything out of the box, or one that excels at specific tasks while requiring additional components for a complete entertainment system.

The Brightness Battle: Why Lumens Matter More Than You Think

The most dramatic difference between these projectors is brightness output, measured in ANSI lumens. ANSI lumens represent the actual light output of a projector under standardized testing conditions – it's the most reliable way to compare how bright different projectors really are.

The BenQ TH685P produces a substantial 3,500 ANSI lumens, while the HAPPRUN manages around 350 ANSI lumens. This isn't just a numbers game – it fundamentally changes how and where you can use each projector.

With 3,500 lumens, the BenQ can project watchable images even with room lights on or during daytime hours with curtains open. You could set it up in a living room for a football game with friends, or use it for presentations in a meeting room with overhead lights. The brightness also means you can project larger images – up to 300 inches – without the picture becoming too dim to enjoy.

The HAPPRUN's 350 lumens, while perfectly adequate in dark conditions, requires careful light control. Any ambient light will wash out the image, making colors look faded and details hard to see. This isn't necessarily a dealbreaker – many home theater enthusiasts prefer dark rooms anyway – but it does limit your options.

From our research into user reviews, the brightness difference becomes most apparent when families want to watch content together. The BenQ accommodates casual viewing scenarios where someone might want to get up for snacks or check their phone without completely ruining the image quality for others. The HAPPRUN demands more commitment to the viewing experience, which can be either a feature or a limitation depending on your household.

Gaming Performance: When Milliseconds Matter

If gaming is important to you, the performance gap between these projectors is enormous. The BenQ TH685P achieves an exceptional 8.3ms input lag at 1080p/120Hz, which puts it in the same league as dedicated gaming monitors. Input lag is the delay between when you press a button on your controller and when the action appears on screen – for competitive gaming, every millisecond counts.

To put this in perspective, most TVs have input lag between 20-50ms, and older projectors often exceeded 100ms. The BenQ's 8.3ms means you'll feel virtually no delay between your inputs and the on-screen action, making it viable for competitive online gaming or fast-paced single-player titles.

The HAPPRUN doesn't specify its input lag, which typically means it's not optimized for gaming. Based on similar projectors in this category, you'd likely see input lag in the 50-100ms range – fine for casual gaming or turn-based strategy games, but problematic for first-person shooters or fighting games where timing is critical.

The BenQ also supports 120Hz refresh rates, meaning it can display 120 frames per second from compatible gaming consoles like the PlayStation 5 or Xbox Series X. This results in smoother motion and can provide competitive advantages in fast-paced games. The HAPPRUN is limited to standard 60Hz refresh rates.

Beyond raw performance numbers, the BenQ includes a Game Mode that enhances visibility in dark scenes without overexposing bright areas – crucial for games where spotting enemies hiding in shadows can determine victory or defeat. There's also a Game Sound Mode that optimizes the built-in speaker for gaming audio cues.

Smart Features: Convenience vs Flexibility

This is where the HAPPRUN Google TV Smart Projector truly shines. It runs full Google TV 11.0, which means you get the complete Android TV experience with access to the Google Play Store, official Netflix app, YouTube, Prime Video, Disney+, and thousands of other streaming services. The "official Netflix" aspect is particularly important – many cheaper projectors can only access Netflix through workarounds or don't support it at all due to licensing restrictions.

The Google TV interface is intuitive and regularly updated, with personalized recommendations across all your streaming services. You can use Google Assistant voice commands through the included remote, asking it to "play Stranger Things" or "show me action movies" without navigating through menus. The HAPPRUN also supports both Google Cast and Apple AirPlay, so you can easily stream content from your phone or tablet.

Wi-Fi 6 support ensures fast, stable connections for 4K streaming, while Bluetooth 5.2 lets you connect wireless headphones or speakers. The dual-band Wi-Fi (2.4GHz and 5GHz) helps avoid congestion in busy wireless environments.

The BenQ TH685P takes the opposite approach – it's purely a display device. You'll need to connect external streaming devices like a Roku Ultra, Amazon Fire TV Stick, or Apple TV to access streaming content. While this adds complexity and cost, it also provides flexibility. You can choose the streaming platform you prefer, upgrade it independently of the projector, and often get better performance than built-in smart features.

From a long-term perspective, external streaming devices tend to stay updated longer than built-in smart platforms. The HAPPRUN's Google TV will receive updates for several years, but eventually support will end. A separate streaming device can be replaced without changing your projector.

Image Quality: Resolution, HDR, and Color Accuracy

Both projectors offer native 1080p resolution with support for 4K content, but they handle this differently. The HAPPRUN can decode and downscale 4K video to its 1080p display, while the BenQ TH685P includes more sophisticated processing for 4K HDR content.

HDR (High Dynamic Range) support varies between the models. The HAPPRUN supports HDR10+, which includes dynamic metadata that optimizes brightness and contrast on a scene-by-scene basis. The BenQ supports HDR10 and HLG with BenQ's projector-optimized processing that's specifically tuned for projection rather than direct display.

However, HDR performance is closely tied to brightness. The BenQ's 3,500 lumens allows it to actually display meaningful HDR improvements – brighter highlights and better contrast. The HAPPRUN's lower brightness limits how effectively it can reproduce HDR content, though it will still look better than standard dynamic range content in dark rooms.

Color accuracy is where the BenQ shows its professional heritage. It covers 95% of the Rec.709 color space, which is the standard for HDTV content. This means colors appear as filmmakers and content creators intended. The HAPPRUN doesn't specify its color gamut coverage, which typically indicates it's not optimized for color accuracy.

Contrast ratios tell an interesting story – the HAPPRUN claims 20,000:1 while the BenQ specifies 10,000:1. However, contrast ratio measurements can be misleading, especially when brightness varies dramatically. In practice, the BenQ's superior brightness and processing likely deliver better perceived contrast in most viewing conditions.

Audio Considerations and Connectivity

Both projectors include built-in speakers – 5-8W depending on the exact model – but don't expect theater-quality audio from either. The HAPPRUN features Dolby-certified 3D stereo sound, while the BenQ uses treVolo audio technology with game-optimized sound modes.

In our experience researching user feedback, most owners of both projectors eventually add external audio. The built-in speakers are fine for casual viewing or when portability matters, but a soundbar or dedicated speakers dramatically improve the experience. Both projectors support various audio output options, though the HAPPRUN's Bluetooth 5.2 makes wireless audio connections more convenient.

Connectivity varies significantly between the models. The HAPPRUN includes HDMI, AV, dual USB ports, and a headphone jack, plus comprehensive wireless connectivity. The BenQ focuses on dual HDMI inputs for connecting multiple gaming consoles or devices, with basic Bluetooth support.

Installation and Setup Flexibility

The BenQ TH685P offers superior installation flexibility with its 1.3x manual zoom lens and throw ratio range of 1.13:1 to 1.46:1. This means you can place it closer to or further from your screen while maintaining the same image size – helpful when dealing with room layout constraints. It also includes vertical keystone correction to square up the image if the projector isn't perfectly aligned with your screen.

The HAPPRUN supports various mounting options including ceiling, tabletop, and wall mounting, but lacks the optical adjustments that make installation easier. You'll need to be more precise about placement to get optimal image geometry.

Both projectors are reasonably portable, with the BenQ weighing 6.2 pounds and featuring a compact design. The HAPPRUN appears similar in size based on user reports, making both viable for outdoor movie nights or temporary setups.

Home Theater Considerations

For dedicated home theater use, your choice depends heavily on your room setup and priorities. If you have a light-controlled room with proper seating and can add external audio and streaming devices, the BenQ TH685P provides superior image quality and gaming performance. Its professional-grade brightness and color accuracy create a more cinematic experience.

The HAPPRUN Google TV Smart Projector excels in casual home theater scenarios where convenience matters more than ultimate performance. It's perfect for apartment dwellers who want a large screen experience without complex installations or multiple components. The integrated smart features mean you can go from unboxing to watching Netflix in minutes.

Making Your Decision: Scenarios and Recommendations

Choose the HAPPRUN Google TV Smart Projector if you want maximum convenience in a dark room environment. It's ideal for renters who can't make permanent installations, families who want simple operation, or anyone who values the all-in-one approach. At the time of writing, it offers exceptional value in the budget smart projector category, typically costing less than the streaming device alone that you'd need with other projectors.

The BenQ TH685P makes sense when performance is your priority and you're willing to invest in a complete system. It's essential if you need bright-room capability, serious gaming performance, or professional-grade color accuracy. While it costs significantly more than the HAPPRUN, it delivers professional-level performance that justifies the investment for the right user.

Consider your long-term plans as well. The HAPPRUN provides immediate satisfaction but may leave you wanting more brightness or gaming performance later. The BenQ represents a more substantial investment but offers capabilities you're less likely to outgrow.

The Bottom Line

These projectors represent two valid but very different approaches to large-screen entertainment. The HAPPRUN Google TV Smart Projector prioritizes convenience and value, delivering a complete streaming experience in dark rooms at an attractive price point. The BenQ TH685P focuses on performance and versatility, offering gaming-monitor responsiveness and bright-room capability at a premium price.

Neither projector is objectively better – they're optimized for different users and scenarios. Your choice should align with your room conditions, performance requirements, and willingness to invest in additional components. Both represent solid value in their respective categories, making this decision more about matching capabilities to your specific needs than finding a clear winner.
