JMGO PicoPlay VS Xiaomi Redmi Projector 4 Pro

The most striking difference in this group is physical size. The JMGO PicoPlay occupies just 1,088 cm³ of volume, while the Xiaomi Redmi Projector 4 Pro displaces nearly 7,394 cm³ — almost seven times more space. In practical terms, the PicoPlay is genuinely pocket- or bag-friendly, whereas the Redmi 4 Pro is a full-sized desktop unit that requires a dedicated shelf or carrying case. If portability is a priority, the PicoPlay holds a commanding advantage here.

On shared ground, both projectors rely on a non-laser light source (LED or lamp-based) and both offer a dedicated smartphone app. Neither product gains an edge from these two attributes since they are evenly matched, though the presence of an app on both units is a welcome convenience for wireless control and content management.

Overall, the PicoPlay clearly wins this group on form factor, trading the bulk of the Redmi 4 Pro for exceptional compactness. The Redmi 4 Pro's larger chassis, however, typically signals room for more powerful internals and cooling — a trade-off that may become relevant when examining performance-related spec groups.

Both projectors output at 1080p resolution, so neither holds a pixel-count advantage. Where they diverge meaningfully is in maximum image size and focus convenience. The JMGO PicoPlay supports projections up to 200″, compared to the Redmi 4 Pro's ceiling of 120″ — a substantial gap that determines whether a projector can fill a true home-cinema wall or is limited to more modest screen setups.

Focus handling is another clear differentiator. The PicoPlay features motorized focus, meaning the lens adjusts automatically at the touch of a button — a genuine quality-of-life upgrade, especially when repositioning the unit frequently. The Redmi 4 Pro offers neither motorized nor manual focus controls according to the provided data, which raises practical questions about setup flexibility. Additionally, the PicoPlay supports HDR10, enabling better contrast and color depth on compatible content, while the Redmi 4 Pro lacks any HDR standard — meaning HDR-encoded video will be tone-mapped down, losing some visual richness.

Across every meaningful differentiator in this group — image size ceiling, focus automation, and HDR support — the PicoPlay holds a clear advantage. Despite its compact body, it punches well above the Redmi 4 Pro on projection capability, making it the stronger choice for users who prioritize image quality and setup convenience.

Connectivity is remarkably consistent between these two projectors. Both carry identical wireless credentials — Wi-Fi, Bluetooth 5.1, AirPlay, Chromecast built-in, and Miracast — covering virtually every mainstream casting and mirroring scenario a user might encounter. At this level of wireless parity, neither device offers a meaningful edge for cable-free use cases.

On the wired side, both share a single HDMI port, which is standard for this category. The one tangible difference is USB: the JMGO PicoPlay includes 2 USB ports versus the Redmi 4 Pro's 1. In practice, that extra port removes the need for a hub when simultaneously connecting, for example, a storage drive and a wireless dongle — a small but real convenience advantage, particularly for the PicoPlay's portable use case where a hub is less likely to be on hand.

Overall, this group is essentially a near-tie, with the PicoPlay claiming a minor edge solely due to its additional USB port. Users who rely heavily on wired peripherals will appreciate it, but for the majority of wireless-first workflows, both projectors are functionally equivalent here.

Audio is where these two projectors part ways most noticeably. The Xiaomi Redmi Projector 4 Pro delivers 2 × 8W stereo sound, while the JMGO PicoPlay is limited to a single 1 × 8W mono speaker. Stereo separation creates a wider, more immersive soundstage — particularly noticeable during music playback or cinematic content — whereas mono output collapses everything to a single point of sound. For built-in audio, this is a meaningful real-world difference.

The Redmi 4 Pro also includes a 3.5 mm audio jack, giving users a straightforward wired path to headphones or external speakers without relying on Bluetooth. The PicoPlay omits this entirely, which limits audio output flexibility — especially in quiet environments where Bluetooth latency or pairing friction might be inconvenient. Both units share a built-in smart TV platform and a remote control, so neither holds an advantage in smart features or day-to-day navigation.

For this group, the Redmi 4 Pro holds a clear edge. Its stereo speaker configuration, doubled total wattage, and wired audio output option collectively make it the stronger standalone audio performer — a notable advantage for users who intend to use the projector's built-in sound rather than routing to an external system.
