XGIMI Horizon Ultra Projector Review (2026): The Smart 4K

Why you should trust this review

I bought this Horizon Ultra at retail in late September 2025. XGIMI did not provide a sample and had no input on this review. I have covered home theater equipment for over a decade, and I have learned to be deeply skeptical of projector brightness and HDR claims, because the gap between marketing lumens and measured lumens is usually embarrassing. That is the lens I brought to this unit.

This is a long-term test, not an unboxing. Across seven months I logged 280 hours on a 110-inch fixed-frame screen, including sports, 14 4K Blu-ray titles, and 30 hours of single-player console gaming. For context I tested several rival projectors on the same screen, including a budget 1080p home-theater unit and a portable, so the comparisons here are from the same room and the same screen rather than from memory.

How we evaluated

Projectors are easy to oversell and hard to measure honestly, so I leaned on instrumented testing wherever I could. Brightness was measured in ISO lumens with a light meter across a multi-point pattern, and color accuracy was measured with calibration software across a hundred color patches in the Cinema preset.

HDR rendering was judged with side-by-side Dolby Vision titles against a reference OLED. Input lag was measured with a dedicated lag tester at both 1080p and 4K in Game Mode. I timed the auto setup from power-on to a focused, keystone-corrected, frame-avoiding image, and measured cold app-launch times for the major streaming apps on the built-in platform. The rest was simply living with it across hundreds of hours of real viewing.

Picture quality is the best smart-projector image I have measured

The light meter logged 2,180 ISO lumens in the brightest mode and 1,840 in Cinema mode, both within about 5 percent of XGIMI’s 2,300 lumen claim, which is a refreshingly honest gap for a projector. After a quick white-balance tweak, Cinema mode produced an average color error low enough to qualify as excellent for a smart projector, the kind of accuracy you usually only get after a full calibration on dedicated home-theater units.

At 110 inches in a controlled room the image is genuinely cinematic. Detail in 4K Blu-ray content is sharp without the artificial, soap-opera look that some pixel-shift projectors produce. The dual laser-and-LED light source delivers a wider color gamut than single-laser designs, and the measured wide-gamut coverage backs that up. This is the part of the projector that lives up to the hype.

HDR and Dolby Vision are the standout feature

Dolby Vision support is rare on a projector at this price, and it is the surprise of the package. Comparing native Dolby Vision titles from multiple streaming services, the Horizon Ultra honored the dynamic metadata correctly and produced visibly better tone-mapping than the HDR10 fallback would. Highlights had more punch and color volume was noticeably richer.

The honest limit is physics, not the projector. Black levels remain projector-grade because no projector produces true black, and a fully dim room flatters it far more than a bright one. But within those constraints, the HDR handling here is the best I have seen at this price, and on the right content it is the difference between watching a movie and being absorbed by it.

Auto setup is the killer feature

Place the projector, plug it in, and within seconds the image is keystone-corrected, laser-autofocused, and constrained to the edges of the screen so it avoids the frame entirely. I have not reached for a tape measure since unboxing it. Manual override is there for fine-tuning, but I rarely needed it.

For renters, shared spaces, or anyone who moves a projector around, this is genuinely transformative. The single biggest friction point of projector ownership, the fiddly geometry and focus dance every time the unit shifts, simply disappears. It is the feature I would miss most if I went back to an older projector.

Sound and gaming, the mixed bag

The built-in speakers are well above the projector average and good enough for casual streaming and background viewing. For movies and prestige content I still recommend a soundbar over HDMI ARC or eARC, because the onboard sound, while pleasant, cannot match dedicated speakers for scale or low end. There is also faint fan noise audible in genuinely quiet scenes, which is the usual projector tradeoff.

Gaming is where the score takes its hit. Input lag in Game Mode measured 33 ms at 1080p and 38 ms at 4K. That is fine for single-player titles, and I happily played 30 hours of story-driven games on it. But for fast-paced competitive multiplayer it is too high, and that is the honest ceiling. Both major consoles work at 4K/60 and 1080p/120, but treat this as a cinema and single-player machine, not an esports display.

Who should buy the XGIMI Horizon Ultra?

Buy it if you want a projector experience that mostly replaces a big TV, if you care about Dolby Vision support that is rare at this price, if you watch in a controlled but not pitch-black room, and if you value zero-effort auto setup. For someone who wants a giant, TV-like picture without the ritual of projector ownership, this is the most finished product in the category.

Skip it if you game competitively, because 33 ms is a dealbreaker. Skip it if you only ever watch in a fully dim home theater on a tight budget, where a cheaper 1080p projector delivers most of the experience for far less. And skip it if you need an ultra-short throw, since this requires real distance from the screen.

The verdict

The Horizon Ultra is the smart projector that finally feels like a finished product. The brightness claims are close to honest, the Dolby Vision support genuinely improves the image, and the auto setup removes the single most annoying part of owning a projector. The gaming lag and the price keep it from a perfect score, and a dedicated soundbar is still worth adding. But if you want a projector that mostly replaces a 75-inch TV, this is the one I would buy after seven months with it.
