Main trade-off
Hisense C3 Ultra
At 8 kg, C3 Ultra is a substantial object to lift onto a shelf. Its body dimensions also understate the space needed for ventilation and cables.
Head-to-head
Hisense C3 Ultra vs XGIMI HORIZON 20 Max: Hisense fits 120 inches from 9 ft, XGIMI carries lighter
The short answer
Choose C3 Ultra when a 120-inch screen must work from about 9 feet, or you need its built-in Ethernet and AirPlay2. Choose HORIZON 20 Max for a Google TV service you have confirmed, or regular room changes with a 5.4 kg body instead of 8 kg. At a 12-foot lens position, both fit 120 inches optically. Neither brightness headline replaces a room and viewing-mode check.
Before you choose
The reasoning and the trade-offs
A nine-foot position makes this a lens decision before it becomes a brightness decision
A family room may have only one place for a projector that leaves the sofa and walking route usable. At 9 feet from the lens, C3 Ultra can make a 120-inch 16:9 picture optically. HORIZON 20 Max tops out around 103 inches from that position. If you can move the lens back to 12 feet, both can fill the same 120-inch screen. Measure that usable position first. The brighter-looking headline cannot compensate for a lens that cannot fill the screen from your furniture.
What this is based on
120-inch 16:9 width = 104.59 inches. Distance = width × throw / 12. C3 Ultra 7.84 to 13.07 ft, HORIZON 10.46 to 13.07 ft. At 9 ft and 1.2 throw, maximum diagonal is 103.3 inches. Assumes a perpendicular image before digital correction, with installation tolerance still needed.
Main trade-off
XGIMI HORIZON 20 Max
Its shortest optical throw needs about 10.5 feet for 120 inches. Digital correction cannot make that picture optically fit a 9-foot position.
Hisense C3 Ultra
- Choose it for
- Your 120-inch screen needs a lens around 9 feet away. Leave the required 20 cm side and rear ventilation space.
- You need the documented Ethernet connection or AirPlay2, with the exact streaming service and content restrictions checked.
- Main trade-off
- At 8 kg, C3 Ultra is a substantial object to lift onto a shelf. Its body dimensions also understate the space needed for ventilation and cables.
XGIMI HORIZON 20 Max
- Choose it for
- You put the projector away regularly and can use its longer optical distance. The body is 2.6 kg lighter.
- Your required service is available on Google TV but needs an external player on VIDAA. Confirm that service before buying.
- Main trade-off
- Its shortest optical throw needs about 10.5 feet for 120 inches. Digital correction cannot make that picture optically fit a 9-foot position.

What matters in practice
The differences that matter
A nine-foot position makes this a lens decision before it becomes a brightness decision
A family room may have only one place for a projector that leaves the sofa and walking route usable. At 9 feet from the lens, C3 Ultra can make a 120-inch 16:9 picture optically. HORIZON 20 Max tops out around 103 inches from that position. If you can move the lens back to 12 feet, both can fill the same 120-inch screen. Measure that usable position first. The brighter-looking headline cannot compensate for a lens that cannot fill the screen from your furniture.
How we reached this conclusion
120-inch 16:9 width = 104.59 inches. Distance = width × throw / 12. C3 Ultra 7.84 to 13.07 ft, HORIZON 10.46 to 13.07 ft. At 9 ft and 1.2 throw, maximum diagonal is 103.3 inches. Assumes a perpendicular image before digital correction, with installation tolerance still needed.
Keeping the room tidy creates a different advantage from keeping the projector installed
If the projector lives on a table only during movies, HORIZON removes 2.6 kg from the body you lift and store each time. If C3 Ultra stays installed, its wider throw range may let you stop moving it altogether. That second option only works with a stable support and the manual’s 20 cm side and rear ventilation space. A cabinet that looks large enough for the body can still be unsuitable. Choose the lighter HORIZON for a repeated carry, or the C3 Ultra placement that genuinely eliminates the carry. Neither recommendation establishes that a particular person can safely lift either unit.
How we reached this conclusion
8.0 minus 5.4 = 2.6 kg, using manufacturer body weights. The carry-versus-install distinction is conditional on room layout and manual clearance. No ergonomic or accessibility test is claimed.
The sports app can decide whether the console needs a switch
Suppose the room already has a console and an eARC-only soundbar. Those use both HDMI sockets on either projector. If the family’s sports service is built into the chosen operating system, the setup stays simple. If that service needs an external player, you now have three devices competing for two sockets. HORIZON is the better fit when the verified Google TV app avoids that extra player. C3 Ultra can be the better fit when its supported VIDAA app and Ethernet connection suit the room. A compatible receiver or soundbar with video passthrough can change the answer. AirPlay is not a universal substitute for protected streaming apps.
How we reached this conclusion
Two HDMI sockets minus one eARC soundbar minus one console leaves zero for a streaming player. Assumes a soundbar without a separate HDMI input. Service availability and format support must be checked for the actual devices.

The result checks hard limits only. Preferences stay out of the calculation.
Hisense C3 Ultra
Fits these inputsFor a 120-inch 16:9 picture, the calculated lens range is about 7.84 to 13.07 ft. Your input is 9.50 ft.

Meaningful differences
What changes the fit
| What changes | Hisense C3 Ultra | XGIMI HORIZON 20 Max | Why it matters |
|---|---|---|---|
| 120-inch optical distance | About 7.8 to 13.1 feet | About 10.5 to 13.1 feet | C3 Ultra can use a closer table. Both can work around 12 feet before digital correction. |
| Body carried between rooms | 8 kg / 17.6 lb | 5.4 kg / 11.9 lb | The 2.6 kg difference matters when the projector leaves the room after each film. Cables and accessories add to both loads. |
| Streaming platform | VIDAA with AirPlay2 and Gigabit Ethernet | Google TV with Google Cast and Wi-Fi 6 | Check the service you actually watch. A required external player changes the HDMI plan. |
| Console and soundbar connections | Two HDMI inputs, eARC on HDMI1, optical and analog audio | Two HDMI inputs, eARC on HDMI1, optical and analog audio | Both directly accommodate one HDMI source plus an eARC-only soundbar. A second source needs another route. |
| Optical shift | Up to vertical 100 percent and horizontal 35 percent | Up to vertical 120 percent and horizontal 45 percent, with full horizontal at vertical zero | These figures are not a promise that a high side corner fits. Confirm the combined envelope and reference position. |
| Published light output | Up to 4,000 ANSI lumens | Up to 5,700 ISO lumens in specified peak mode | No matched movie-mode test supports a percentage brightness advantage from these two headlines. |
What you give up
Every choice has a cost
If you choose Hisense C3 Ultra
- AirPlay2 does not guarantee that every protected video service can be mirrored. A missing VIDAA app may still need a separate HDMI player.
If you choose XGIMI HORIZON 20 Max
- The 5,700 ISO peak mode may change color and fan noise. Its 1 ms claim is at 1080p240 with VRR on and auto keystone off, not at 4K from any shelf.
Recommendation switch
The decision flips if...
The 120-inch lens position is around 9 feet
Choose Hisense C3 Ultra. C3 Ultra fits optically while HORIZON needs more distance.
You carry it regularly and the longer throw fits
Choose XGIMI HORIZON 20 Max. HORIZON removes 2.6 kg from the body load.
Three HDMI devices must connect directly
Choose neither. Both need a suitable switch, receiver or different audio route.
What matters in practice
Before you choose
You want a large picture without keeping a heavy projector in the middle of the room. A shorter throw can clear the walking route, while a lighter body is easier to put away.
What this comparison cannot tell you
- No matched noise, brightness, contrast or input-lag test was performed.
- C3 Ultra documentation differs on automatic adjustment for screens above 150 inches. Confirm the intended function and software before relying on it.
- A protection sensor does not make looking into the beam safe. Follow supervision and eye-safety instructions.
