The $2,999 JMGO N3 Ultimate is a 4K laser projector that’s pricey, but delivers easy placement, paired with excellent video quality. Too bad it’s badly let down by Google TV software.
Most projectors assume you can put them exactly where they need to be. Real living rooms rarely work that way.
The usual fix is digital keystone correction, which electronically adjusts a skewed image to look straight. It works, but it costs you resolution and brightness in the process.
The N3 Ultimate is built around avoiding that trade-off entirely. JMGO calls its combination of placement tools the 3-in-1 system, and it takes a different approach to each part of the problem.
We previously reviewed JMGO’s N1S Ultra, which delivered excellent picture quality but left us wanting more from its smart TV software and speaker output. The N3 Ultimate sits higher in JMGO’s lineup and addresses several of those sticking points.
Not all of them, though.

JMGO N3 Ultimate review: Physical design
The N3 Ultimate measures 12.1 by 9.1 by 10.8 inches and weighs 15.3 pounds. That is a significant unit, but not an immovable one.
The most distinctive physical feature is the gimbal head, which houses the lens and rotates independently from the base. This is what lets the projector stay on a flat surface while pointing at a wall or ceiling without physically moving the whole unit.
The body is built from aluminum, which helps keep things cool given the powerful laser light source inside. It is clearly a living room piece rather than something you’ll move around often.
Around the back are two HDMI 2.1 ports, one of which supports eARC (which allows the projector to send audio back out to a connected sound system without a separate cable), plus a USB 3.0 port. Wi-Fi 6 and Bluetooth 5.2 handle wireless connectivity.
The built-in speaker system is 25W total across two channels. Noise output is rated below 26dB during operation.
JMGO N3 Ultimate review: The 3-in-1 placement system
The N3 Ultimate’s central selling point is how it handles placement. It tackles this in three ways.
The first is the optical zoom, which covers a 0.88 to 1.7:1 throw ratio. In practical terms, a 100-inch image can be produced from as close as roughly seven feet or as far as around fourteen, without affecting image quality.
The second is dual-direction lens shift, which moves the image up, down, left, or right by up to 130% vertically and 53% horizontally. Crucially, this is a purely optical adjustment, unlike digital keystone correction, so there is no loss of resolution or brightness.
The third is the AI gimbal, which JMGO claims is a first for the US market. It rotates the projector head automatically, letting it point at a different wall or the ceiling without the user touching the unit.
All three work together under JMGO’s Optical Image Optimization system. A single button press triggers automatic screen fitting, focus, keystone correction, and obstacle detection at the same time. A feature called AI Spatial Memory then stores those setups, so the projector can switch between surfaces without needing to recalibrate each time.
Use the automatic system. Manually doing it from the remote is fussy, and you will ultimately get frustrated by the process.
JMGO N3 Ultimate review: Image quality
The light source is a tri-color RGB laser, which JMGO calls MALC 5.0. It is the latest version of the same system used in the N1S Ultra we reviewed previously, with improved brightness and color figures.
The system is decent, with it minimizing speckling. There’s still the occasional rainbow effect at play.
Rainbow effect is a visual aberration. Not everyone is sensitive to this effect. Some users, including two of the five viewers on our panel, can see this on other projectors as flashes of red, blue, and green color during high-contrast scenes, or action shots.
In short, it’s a slight strobing around movement.
Our five-person testing panel watched a bunch of action movies, as they seem to show off and challenge projectors the most. With some other lower-end projectors, our testers saw the rainbow effect in a Star Wars fighter battle, and so forth.
One of our two testers saw the rainbow effect while watching the latest Dune movie. The other didn’t see it on Dune, but did see it in Star Wars: Andor‘s escape from the prison, as the escapees jumped into the water.
Good enough.
Output is rated at up to 5,800 ISO lumens. That is more than double the N1S Ultra’s 2,800 lumens, which is a meaningful jump for use in rooms with ambient light.
Contrast is rated at 20,000:1 using FOFO measurement (a standardized method that measures contrast in real projection conditions, rather than in a darkened test environment). This is supported by AI Dynamic Black processing and Shadow Detail Enhancement.
Color coverage is 110% of the BT.2020 standard, with a color accuracy rating of Delta E approximately 0.7. A Delta E below 1.0 is generally considered reference-grade, so this figure is impressive on paper.
Our AV expert brought his hardware over to the house to test the claims. The claims matched up with reality, with the expert measuring a more reasonable 0.8 Delta E in practice.
Still, this varies in testing environments. Like hard drive speeds in the real world not matching up with manufacturer’s claims, this is close enough.
HDR support covers Dolby Vision and HDR10. However, while Dolby Vision seems perfect, support for the plainer HDR10 support is a little off when it comes to color on both Google TV and a connected Apple TV set-top box. Our AV expert didn’t have an answer for why, but said that it “was still reasonable” in a unit at this price point.
From a regular viewer’s standpoint, this isn’t terrible. It is noticeable if you’re viewing something that does not support Dolby Vision.
The image can scale from 40 inches up to 300 inches. This is a good range, especially if you want to watch on a big screen and you happen to have a clear side of your home available for outdoor viewing.
JMGO N3 Ultimate review: Smart features and software
The N3 Ultimate runs Google TV with native Netflix support. It has 4GB of RAM and 64GB of storage, which is generous for a projector.
When we reviewed the N1S Ultra, Google TV’s performance on JMGO’s hardware was a weak point. The MT9679 chip is used again here, so the same limitations apply.
For Apple users, the N3 Ultimate supports AirPlay, allowing iPhones and Macs to stream or mirror content directly to the projector without extra hardware. The Apple TV app is also available via Google TV.
For a cleaner Apple experience overall, pairing with an Apple TV box via one of the HDMI 2.1 ports remains the recommended approach, as it was with the N1S Ultra.
AI features include automatic screen fitting, focus, keystone correction, obstacle avoidance, eye protection, and wall color adaptation. The AI Spatial Memory system can store multiple projection setups, including position, image size, and the last-used app, for quick switching between surfaces.
Calling all this “AI” is marketing, and not much else. A few years ago, it’d have been called “computer vision” or the like.
And, we hooked up an Xbox Series X to the N3 Ultimate. Input lag is rated at 1ms, and it supports Variable Refresh Rate (VRR) that synchronizes the projector’s frame output with the console or PC for smoother motion. It also has up to a 240Hz refresh rate, but at a lower resolution that max.
A dedicated Pro Game Mode is also available. These figures are competitive with dedicated gaming monitors, which is unusual for a projector. Our test group liked the feature, and compared it positively to the 120Hz 4K display that I have on my desk.
PlayStation 5 and Xbox Series X users benefit from VRR directly over the HDMI 2.1 connections. Apple TV 4K users pairing via HDMI will also see a responsive, low-lag connection.
Upscaling of retro consoles is better handled by an emulator or an external box, though, if that’s your thing.
JMGO N3 Ultimate review: Audio
The N3 Ultimate has a 25W stereo speaker system with Dolby Audio and DTS-X support. That is a step up from the N1S Ultra’s 20W setup in name, though the configuration differs.
As with just about every projector’s speaker systems, whether this is adequate for your large-screen setup is something only hands-on use will confirm. We didn’t like it, and preferred our own Dolby Audio solution.
As was the case with the N1S Ultra, external audio is probably what you want. A soundbar or, for Apple users, a receiver with external speakers or a full-sized HomePod paired in low-latency mode via Apple TV, makes the most of what the projector can deliver.
JMGO N3 Ultimate review: A more complete package
The N3 Ultimate builds directly on what JMGO established with the N1S Ultra. The picture is substantially better, the placement system is more flexible, and the gaming credentials are genuinely competitive with screens.
The 3-in-1 system is a real differentiator. For users who cannot mount a projector to a ceiling, or who want flexibility in how they use a room, the ability to repoint the projector automatically without losing image quality is worth paying for.
At a MSRP of $2,999, it is a premium product. It is priced for people who want the best image they can get in a living room context, and who value placement flexibility alongside it.
That Google TV, though, is awful. It’s slow, it’s not very responsive, and it’s janky. All of this is not JMGO’s fault, and Google might be able to make it better. Eventually. Maybe.
But, Google is on Google TV 5.0, though. You’d think they’d have fixed it by now.
Apple users will find it integrates well with an Apple TV or Mac mini in the chain. It is clearly not an Apple product, but it is a good projector for one.
JMGO N3 Ultimate Pros
- 3-in-1 lossless placement system
- Significantly improved brightness over previous models
- Competitive gaming specs
JMGO N3 Ultimate Cons
- Premium price
- Google TV performance is very bad
- Onboard audio is a bit weak, and should be replaced with another solution
Rating: 4 out of 5
I liked the JMGO N1S Ultra. I like the N3 more, but I still hate Google TV.
AirPlay to the unit natively isn’t enough. Hook it up to an Apple TV with HDMI, and that removes most of the friction of the product for Apple users.
