The catch
Hisense C3 Ultra
For 120 inches, its longest optical throw gets to about 13.1 feet. At a 14-foot position you would need a larger picture, digital shrinking or a closer lens.
Side by side
Hisense C3 Ultra vs JMGO N3 Ultimate for shelf and sound: Hisense adds optical audio, N3 fits 120 inches from 14 ft
Quick verdict
The N3 Ultimate is for a 120-inch picture that has to come from a rear shelf around 14 feet away. The C3 Ultra is for direct optical audio to an existing soundbar, or for built-in Ethernet. From 10 feet, both fit the screen optically. If two consoles and an optical-input soundbar all need to stay connected, the C3 Ultra has the simpler direct connection plan, once audio formats are checked.
Before you buy
Why, and what it costs you
N3’s extra reach may be needed for a rear shelf that keeps the family route clear
Put a 120-inch screen at the front of a shared room and you may find an inviting shelf about 14 feet behind it. N3 Ultimate can fit that screen optically. From the same distance, the smallest optical picture C3 Ultra can make is about 128 inches, so it would need digital shrinking or a different position. That gap counts when moving the projector forward would put it in the room’s walking route. At 10 feet both fit 120 inches, and the extra long-end zoom is no longer a reason to pick N3. All these measurements start at the lens and leave out shelf, cable and ventilation clearance.
Where this comes from
A 120-inch screen at 16:9 is 104.59 inches wide. N3 range = 104.59 × 0.88 to 1.7 / 12 = 7.67 to 14.82 ft. C3 Ultra = 7.84 to 13.07 ft. With a 1.5 throw at 14 ft, the minimum optical diagonal is 128.5 inches. This assumes a perpendicular image and does not model installation tolerance.
The catch
JMGO N3 Ultimate
Its documented connectors give HDMI/eARC audio and no direct optical output. To keep an optical-only soundbar, you would need a compatible source output or an adapter.
Hisense C3 Ultra
- Why pick it
- The soundbar you have takes an optical input, and you want both HDMI sockets free for sources. Confirm the audio formats of the soundbar and the sources.
- Wired Ethernet is available at the shelf you chose and you want a built-in network socket, with enough room for the 8 kg body and ventilation.
- The catch
- For 120 inches, its longest optical throw gets to about 13.1 feet. At a 14-foot position you would need a larger picture, digital shrinking or a closer lens.
JMGO N3 Ultimate
- Why pick it
- For your 120-inch screen, the lens position is around 14 feet away, and you would like to avoid both digital shrinking and moving the shelf.
- The service you picked runs on Google TV, and your equipment already works with the HDMI/eARC audio route.
- The catch
- Its documented connectors give HDMI/eARC audio and no direct optical output. To keep an optical-only soundbar, you would need a compatible source output or an adapter.

Differences you will notice

Put a 120-inch screen at the front of a shared room and you may find an inviting shelf about 14 feet behind it. N3 Ultimate can fit that screen optically. From the same distance, the smallest optical picture C3 Ultra can make is about 128 inches, so it would need digital shrinking or a different position.

How we worked this out
A 120-inch screen at 16:9 is 104.59 inches wide. N3 range = 104.59 × 0.88 to 1.7 / 12 = 7.67 to 14.82 ft. C3 Ultra = 7.84 to 13.07 ft. With a 1.5 throw at 14 ft, the minimum optical diagonal is 128.5 inches. This assumes a perpendicular image and does not model installation tolerance.
An older soundbar you keep can leave room for both consoles
Say the household has two consoles and a soundbar with a usable optical input. C3 Ultra can give each console an HDMI input and send compatible audio out through its separate optical socket. N3’s published connector panel shows no equivalent direct optical route. An eARC soundbar would take one of its two HDMI sockets and leave only one for consoles. A receiver, a suitable extractor or a source with separate audio can make N3 work, but check format support and the total equipment cost. A soundbar with its own HDMI input and suitable passthrough can remove the conflict. Here C3 Ultra’s edge is that a particular setup can be reused with fewer extra boxes.
How we worked this out
The port allocation is inferred from the connector lists for each exact model and from rear panels checked by eye. It assumes two HDMI consoles and an optical-input soundbar with no video passthrough. Optical audio depends on the source and soundbar supporting compatible formats, and it does not equal eARC format support.
A wired shelf is useful only when the streaming service fits too
If a cable is already run to a rear shelf, C3 Ultra’s Ethernet socket can use it and spare that connection from relying on Wi-Fi. Its built-in VIDAA apps still have to cover the films or sports you want. If they don’t, an external player may take an HDMI input you meant to keep for a console. N3 may do without that player when the exact Google TV service is supported, but its published panel has no built-in Ethernet socket. Look at the app, the network route and the source count together. Faster Wi-Fi branding can’t fix a missing service or a congested room.
How we worked this out
This combines connection and software availability with a fixed network cable and shared demand for HDMI. No measured buffering advantage is claimed. USB Ethernet compatibility is not assumed for either projector, and an app missing from a list does not prove the app is unavailable.

Spec by spec
Where they really differ
| Spec | Hisense C3 Ultra | JMGO N3 Ultimate | In practice |
|---|---|---|---|
| 120-inch optical distance | About 7.8 to 13.1 feet | About 7.7 to 14.8 feet | A rear shelf farther back works for N3. The difference at the short end is too small to stand in for a careful installation check. |
| Keep an optical-input soundbar | Dedicated optical audio output | HDMI/eARC audio on the published connector panel | The direct optical route is on C3 Ultra. N3 needs compatible extra equipment, or a source that has its own output. |
| Two consoles plus audio | Two HDMI sources can remain connected when compatible optical audio is used | An HDMI/eARC soundbar occupies one of the two HDMI sockets | How many source devices can stay connected without cable swapping comes down to the audio route. |
| Network at the fixed shelf | Built-in Gigabit Ethernet and Wi-Fi 7 | Wi-Fi 6, with no Ethernet socket in the published panel | C3 Ultra may be the better fit for a wired room. Neither protocol label proves a specific internet speed. |
| Streaming and carry weight | VIDAA, 8 kg body | Google TV, 6.95 kg body | Treat apps and physical handling as separate checks from what the gimbal can do to aim the image. |
| Published image claims | 4,000 ANSI maximum, seven manually selected iris levels | 5,800 ISO claim with dynamic black-level processing | No matched brightness or dark-scene winner comes out of these figures. |
Trade-offs
What each pick costs you
With Hisense C3 Ultra
- Not every format that eARC carries survives over optical audio. Confirm the formats you need before you use optical to free up an HDMI socket.
With JMGO N3 Ultimate
- When an eARC-only soundbar takes the other of two HDMI inputs, only one source input is left. Google TV doesn’t prove support for every streaming service or format.
Change of plan
When the answer changes
At 120 inches, the lens sits around 14 feet back at the rear
Go with JMGO N3 Ultimate. The projector can stay at the back of the room because N3 fits optically.
Optical audio on its own, with both HDMI inputs left free
Go with Hisense C3 Ultra. C3 Ultra provides the documented direct route, as long as the supported formats are checked.
Three HDMI devices all have to connect directly
Neither model fits. A different connection plan is required for either.
Decision guide
Before you buy
The goal is a modern big-screen setup that still keeps your rear shelf and a sound system that works. One projector offers more optical reach, and the other offers more direct ways to reuse older equipment.
What this page can’t tell you
- No lumen or contrast headline here comes from a matched laboratory comparison.
- We do not assume the published shift axes can all be maxed at once.
- The documents for the C3 Ultra disagree about automatic adjustment above 150 inches. Do not count on a large-screen setup that runs unattended.
