Highlights

Marketed as a versatile portable smart projector, the Polocsh HY300Pro boasts features like Android TV 11.0 and 210° rotation, positioning it for home theater, outdoor use, and casual entertainment. However, a detailed examination of advertised specs against user experiences uncovers typical exaggerations in budget projectors, where performance often prioritizes affordability over premium quality.

The projector is advertised with 10,000 Lumens or 260-290 ANSI Lumens brightness, implying suitability for various lighting conditions, but independent tests and user reports peg the actual output at around 100-160 ANSI Lumens. This means the device excels solely in pitch-black environments, with any ambient light causing significant washout, a common marketing overstatement in entry-level models.

A key highlight is the native 720P (1280×720) resolution, with support for 1080P and 4K decoding, which provides decent clarity for everyday viewing. Yet, the 1080P/4K claims refer only to input handling, not native projection; in practice, images soften and pixelate on larger screens, as confirmed by Reddit and YouTube reviews noting fuzzy edges and reduced sharpness.

Contrast ratio is listed as 15,000:1 or 3,000:1, suggesting deep blacks and vibrant visuals, but real-world measurements indicate a much lower effective ratio of about 1,000:1 or less. Blacks often appear gray, particularly in lit rooms, due to inherent LED constraints, leading to washed-out colors as highlighted in user forums and review sites.

The throw ratio of 0.9-1.1 enables short-throw projections, ideal for compact spaces, and aligns well with practical use. Combined with a min/max throw distance of 1.2m-4m, it offers flexibility in small rooms, though image quality diminishes at the extremes, with users recommending 2-3m for optimal focus and brightness, per Reddit feedback.

Lamp life is promoted at 30,000 hours for the LED source, a standard claim for longevity, but reports of overheating and failures suggest it often lasts only 6-12 months under regular use. No long-term independent data supports the full advertised lifespan, underscoring potential reliability issues in budget electronics.

Connectivity options include WiFi 6 (dual-band), Bluetooth 5.2, HDMI, USB, AV, and Audio Out, facilitating easy integration with devices. In reality, WiFi proves unreliable on 5GHz bands with streaming lags, Bluetooth suffers from audio sync problems, and while HDMI/USB work for basic inputs, format limitations and OS bugs cause frequent drops, as noted in widespread user complaints.

Auto keystone correction is a touted feature for quick setup, but it frequently requires manual adjustments and falters after firmware updates, with users reporting stuck or ineffective corrections. This makes alignment less seamless than advertised, especially in dynamic placements.

The digital zoom up to 50% allows image sizing without repositioning, yet as a non-optical function, it reduces resolution and introduces quality loss. Reviews confirm it as a basic tool, lacking the versatility of true lens zoom found in higher-end projectors.

Input lag is not explicitly advertised but implied as low for gaming; however, estimates place it at 30-50ms or higher, rendering it unsuitable for fast-paced games like FPS. User threads advise against it for serious gaming due to noticeable delays.

Audio is handled by built-in HiFi speakers with Dolby support and 360° surround, promising immersive sound, but the output is weak, tinny, and bass-deficient, distorting at high volumes. Most experiences recommend external speakers via Bluetooth or jack, aligning with Reddit consensus that onboard audio suits only casual, low-volume scenarios.

The aspect ratio of 16:9 / 4:3 supports standard content formats and auto-adjusts effectively, with no significant discrepancies reported, making it reliable for movies and presentations.

Weighing approximately 0.5-1 kg, the projector lives up to its portable claim, facilitating easy transport for outdoor or travel use without any noted inconsistencies in build or weight.

Lens shift is absent, as expected in this fixed-lens budget model, relying entirely on physical positioning for alignment, which is standard but limits advanced setup options.

The IR remote with mouse mode provides basic control, but OS navigation feels clunky, and firmware updates often lead to unresponsiveness, per user reports on remote functionality issues.

Noise level is claimed at <25 dB for quiet operation, yet actual fan noise reaches 30-40 dB, creating a distracting hum during quiet scenes, as complained about in reviews highlighting the constant “air sound.”

Projection size ranges from 40″-150″ or up to 200″, which is achievable, but quality degrades beyond 100″ due to brightness and resolution constraints; optimal viewing is at 80-100″ in dark rooms, based on user experiences.

Additional features encompass Android TV 11.0, 210° rotatable design, auto focus, streaming apps like Netflix, and dust-proof construction. Nevertheless, the OS is plagued by bugs, app crashes, and update-induced bricking; rotation can be unstable, auto features inconsistent, and no built-in battery exists despite occasional claims, with overheating a common grievance in Reddit discussions.

In essence, the Polocsh HY300Pro serves as an economical entry into portable projection, excelling in dark, controlled settings with its native 720P resolution and short-throw capabilities. However, overstated brightness, contrast, and audio, coupled with buggy software and reliability concerns, reflect standard budget trade-offs. It suits casual users prioritizing portability and low cost, but those desiring robust performance in varied conditions or long-term durability may find better value in established brands with verified specs.
