The catch
JMGO N1S Ultra
The gimbal changes the aim but not the image size from a given distance, because the throw ratio is fixed.
Side by side
The N1S Ultimate is the pick if you want more published light output for a larger picture. If your planned screen already suits the N1S Ultra and the extra output wouldn't solve a particular problem, go with the Ultra. Both share the fixed 1.2 throw ratio, Google TV and 20W speaker specification.
Before you buy
If conditions are equal, Ultimate's output ratio could support a picture of about 130 inches, compared with the 120 inches for Ultra at the same nominal light per area. Treat this as an illustration. It is not a measured viewing recommendation.
Where this comes from
3,300 ÷ 2,800 = 1.179 as the area ratio. The diagonal grows with the square root of area, giving 120 × √1.179 = 130.3 inches. This assumes the same screen gain, aspect ratio, mode losses and calibration.

The catch
With a fixed 1.2:1 throw ratio and no optical zoom, changing the image size means moving the unit.

A screen-size calculation, the lens limits both share and practical buying advice for a dark room or a larger picture, comparing JMGO N1S Ultra and N1S Ultimate.
The two are close relatives, sharing the same nominal lens and core streaming setup. The question worth asking is how much picture-size headroom the extra output can reasonably buy.
Which one fits
The nominal throw ratio is identical on both.
The Ultimate has a higher published ISO rating to spread over the picture.
With the same fixed lens on both, that constraint stays.
Those requirements are already met by both.
In practice
If conditions are equal, Ultimate's output ratio could support a picture of about 130 inches, compared with the 120 inches for Ultra at the same nominal light per area. Treat this as an illustration. It is not a measured viewing recommendation.
3,300 ÷ 2,800 = 1.179 as the area ratio. The diagonal grows with the square root of area, giving 120 × √1.179 = 130.3 inches. This assumes the same screen gain, aspect ratio, mode losses and calibration.
A 120-inch picture takes about 10.5 feet with either one. If nine feet is all your room allows, neither can reach that screen size optically.
A 16:9 image at 120 inches is 104.6 inches wide. Times the shared 1.2 ratio, divided by 12, that is 10.46 feet.
Both have Google TV, native Netflix, HDR10 and a 20W speaker specification. These are good reasons to pick either one, but none of them justifies an upgrade.
The comparison draws the same fields from JMGO's exact US specifications for the N1S Ultra and N1S Ultimate.
Plug in your numbers
This checks hard limits only. Personal preferences are left out of the math.
For a 120-inch 16:9 picture, the calculated lens position is about 10.46 ft. You entered 9.50 ft.
For a 120-inch 16:9 picture, the calculated lens position is about 10.46 ft. You entered 9.50 ft.
Measure distance from the lens to the screen. The math assumes a 16:9 picture and uses the verified throw range for each exact model.

Spec by spec
| Spec | JMGO N1S Ultra | JMGO N1S Ultimate | In practice |
|---|---|---|---|
| Published brightness | 2,800 ISO lumens | 3,300 ISO lumens | Ultimate gives more stated light output and leaves the room geometry as it was. |
| Throw ratio | Fixed 1.2:1 | Fixed 1.2:1 | Neither one adds optical zoom to suit the shelf you have. |
| Native streaming | Google TV with Netflix | Google TV with Netflix | Both give the same day-to-day access to those services. |
| HDR specification | HDR10 | HDR10 | Neither of the pair opens up a new Dolby Vision playback path. |
| Speaker output | 20W | 20W | The published power rating by itself does not set them apart. |
| 120-inch optical distance | About 10.5 ft | About 10.5 ft | The throw you need stays just as long after the upgrade. |
Trade-offs
Decision guide
The Ultimate is an output upgrade for the same basic setup. It does not fix an awkward projector position.
Light spreads thinner across a larger picture. If you're still choosing the screen, the Ultimate gives you some additional rated output to work with. When the screen is already installed and looks bright enough, the advantage is less compelling than the model names suggest.
Fixed 1.2:1 optics are used by both, so upgrading won't get you a larger image from a shorter distance. Measure the lens position now, particularly if the only shelf is behind the sofa. Set image size by physical placement wherever possible, and then apply only the correction the room needs.
Stands, glasses and other accessories can vary between Amazon packages. Compare the complete items you would otherwise need to buy, and keep the projector names straight. The included Google TV system and the published 20W speaker rating don't turn the Ultimate into a different kind of everyday streaming device.
By the numbers
What we found across the home projectors we compare, plus the checked facts behind each finding.
Only 17 of the 90 models checked meet every need here: “My movie watching is mostly in a dark room”, “I am after a picture of 120 inches or larger”, and “I want Netflix working from day one”.
17 models fit, out of 90 checkedJMGO N1S Ultimate lists 3,300 ISO lm for listed ISO brightness, 18% more than the 2,800 ISO lm on JMGO N1S Ultra.
How we countedThe count uses each product's current fit ratings for “My movie watching is mostly in a dark room”, “I am after a picture of 120 inches or larger”, and “I want Netflix working from day one”. A need with no documented match is not counted.
How we calculatedThis median counts ISO-lumen figures alone. ANSI ratings and lumen labels used only by the maker stay out. For context, 44 of 90 models publish comparable figures.
