BenQ TK705STi VS XGIMI Horizon 20 Max

Both the BenQ TK705STi and the XGIMI Horizon 20 Max share a laser light source and a dedicated smartphone app, placing them on equal footing in two of the most consequential general-info categories. Laser light sources deliver longer-lasting brightness, lower maintenance, and faster warm-up times compared to traditional lamp or LED-based projectors, so neither unit holds an advantage here.

Where the two diverge meaningfully is in their physical profiles. The XGIMI is notably more compact, with a volume of roughly 6,167 cm³ versus the BenQ's 9,775 cm³ — about 37% bulkier. The XGIMI achieves this through a shorter, squarer footprint (136 mm thick), making it easier to slot into tight AV cabinets or carry in a bag. However, that compactness comes at a cost: the XGIMI weighs 4,900 g compared to the BenQ's 3,800 g, a difference of over 1 kg. In practice, the BenQ is noticeably easier to lift, reposition, or ceiling-mount repeatedly.

Overall, neither product dominates this category outright. The XGIMI Horizon 20 Max has the edge for users prioritizing a smaller physical footprint and shelf-friendly design, while the BenQ TK705STi is the better pick for those who frequently move or reposition the unit and prefer lower carrying weight. Your choice here hinges on whether placement flexibility or portability matters more to you.

On paper, both projectors share the same headline specs: 4K output resolution and full support for HDR10+, HDR10, and HLG — meaning neither has an advantage in color volume standards or pixel density. The real differentiation in this group comes from motion handling and installation flexibility, where the two units diverge sharply.

The XGIMI Horizon 20 Max pulls ahead decisively in raw performance metrics. Its 240Hz refresh rate versus the BenQ's 60Hz is a fourfold difference that matters most for fast-motion content — sports, action films, and especially gaming — where smoother frame rendering reduces blur and judder. Paired with a 1 ms response time compared to the BenQ's 5 ms, the XGIMI is clearly tuned for low-latency, high-motion use cases. The BenQ's 5 ms is still acceptable for casual gaming and cinema, but it cannot match the XGIMI's responsiveness. The XGIMI also supports a dramatically larger maximum image size of 300″ versus the BenQ's 160″, making it the only viable option for true large-venue or dedicated home theater installations.

However, the BenQ TK705STi reclaims ground on installation practicality: its minimum throw distance of 0.8 m means it can fill a usable screen from just under a meter away, a major advantage in smaller rooms. The XGIMI requires at least 2.1 m of throw distance, limiting placement options considerably. In summary, the XGIMI Horizon 20 Max holds a clear edge in projection quality for performance-driven and large-space setups, while the BenQ is the more adaptable choice for constrained or compact rooms.

The wired connectivity foundation is identical: both projectors offer 2 HDMI ports, 2 USB ports, and no RJ45 ethernet jack. Wireless casting support — AirPlay, Chromecast built-in, and Bluetooth — is also shared across both units, giving either projector solid multi-ecosystem streaming compatibility out of the box.

The most consequential difference here is that the BenQ TK705STi lacks built-in Wi-Fi, which is a significant constraint in a modern smart projector. Without Wi-Fi, the BenQ depends on a wired HDMI source or an external streaming dongle to access network content, while the XGIMI Horizon 20 Max connects natively to wireless networks. The XGIMI also supports Miracast, adding Android screen mirroring without extra hardware — something the BenQ cannot do. On the legacy side, the XGIMI includes a DVI connector, which widens compatibility with older PC hardware, though this is a niche advantage for most users.

The BenQ does counter with one exclusive: an S/PDIF optical audio output, which enables a direct digital connection to a soundbar or AV receiver without an HDMI ARC setup. That said, the absence of Wi-Fi is too fundamental a gap to overlook. The XGIMI Horizon 20 Max holds a clear connectivity advantage, particularly for users who want a standalone smart projector experience. The BenQ TK705STi is better suited to setups where it will always be paired with a dedicated media source via HDMI, and where optical audio output is a priority.

Several feature pillars are shared: both projectors include a built-in smart TV platform, stereo speakers, a remote control, and a 3.5 mm audio jack. These are table-stakes for modern projectors at this tier, so they don't move the needle competitively. The real story in this group is how consistently the XGIMI Horizon 20 Max outpaces the BenQ across the differentiating features.

The most practically significant gap is in image alignment. The XGIMI offers both vertical and horizontal lens shift, while the BenQ TK705STi has neither. Lens shift allows physical optical adjustment of the projected image without moving the projector body or relying on digital keystone correction — which degrades image sharpness. For users who can't place their projector in a perfectly centered position, the absence of lens shift on the BenQ can be a meaningful installation headache. The XGIMI also delivers more audio power at 2 x 12W versus the BenQ's 2 x 8W — a 50% increase in rated output that translates to a louder, more room-filling sound without an external speaker, though audio quality depends on more than wattage alone.

Rounding out the XGIMI's advantages, it adds voice command support, which the BenQ lacks entirely — a convenience feature that matters for hands-free control in a living room setting. Taken together, the XGIMI Horizon 20 Max holds a clear and multi-fronted edge in this category, particularly for users who value flexible installation and a more self-contained, feature-rich experience.
