Main trade-off
JMGO N1S Ultra
Its fixed throw ratio means the gimbal changes aim but not image size from a given distance.
Head-to-head
Choose the N1S Ultimate if you want more published light output for a larger picture. Choose the N1S Ultra when your planned screen already suits it and the extra output does not solve a specific problem. The fixed 1.2 throw ratio, Google TV and 20W speaker specification are shared.
Before you choose
Under equal conditions, Ultimate's output ratio could support about a 130-inch picture where Ultra uses 120 inches at the same nominal light per area. That is an illustration, not a measured viewing recommendation.
What this is based on
3,300 ÷ 2,800 = 1.179 for area. Diagonal scales with the square root of area, so 120 × √1.179 = 130.3 inches. Assumes equal screen gain, aspect ratio, mode losses and calibration.
Main trade-off

Main trade-off
The fixed 1.2:1 throw ratio offers no optical zoom, so image size changes require moving the unit.


Compare JMGO N1S Ultra and N1S Ultimate with a screen-size calculation, shared lens limits and practical buying advice for a dark room or larger picture.
These are close relatives with the same nominal lens and core streaming setup. The useful question is how much picture-size headroom the output increase can reasonably buy.
Winner by situation
Both use the same nominal throw ratio.
Ultimate has a higher published ISO rating to distribute across the image.
The shared fixed lens does not solve that constraint.
Both already cover those requirements.
What matters in practice
Under equal conditions, Ultimate's output ratio could support about a 130-inch picture where Ultra uses 120 inches at the same nominal light per area. That is an illustration, not a measured viewing recommendation.
3,300 ÷ 2,800 = 1.179 for area. Diagonal scales with the square root of area, so 120 × √1.179 = 130.3 inches. Assumes equal screen gain, aspect ratio, mode losses and calibration.
Both need about 10.5 feet for a 120-inch picture. If your room offers only nine feet, neither reaches that screen size optically.
A 120-inch 16:9 image is 104.6 inches wide. Multiply by the shared 1.2 ratio and divide by 12 to get 10.46 feet.
Google TV, native Netflix, HDR10 and a 20W speaker specification are present on both. They support choosing either model but do not explain an upgrade.
The comparison uses the same fields from JMGO's exact N1S Ultra and N1S Ultimate US specifications.
Try your real numbers
The result checks hard limits only. Preferences stay out of the calculation.
For a 120-inch 16:9 picture, the calculated lens position is about 10.46 ft. Your input is 9.50 ft.
For a 120-inch 16:9 picture, the calculated lens position is about 10.46 ft. Your input is 9.50 ft.
Distance is measured from the lens to the screen. The calculation uses a 16:9 image and the verified optical throw range for each exact model.

Meaningful differences
| What changes | JMGO N1S Ultra | JMGO N1S Ultimate | Why it matters |
|---|---|---|---|
| Published brightness | 2,800 ISO lumens | 3,300 ISO lumens | Ultimate adds stated light output without changing the room geometry. |
| Throw ratio | Fixed 1.2:1 | Fixed 1.2:1 | Neither adds optical zoom for an existing shelf. |
| Native streaming | Google TV with Netflix | Google TV with Netflix | Everyday access to those services is shared. |
| HDR specification | HDR10 | HDR10 | This pair does not buy a new Dolby Vision playback path. |
| Speaker output | 20W | 20W | The published power rating alone does not separate them. |
| 120-inch optical distance | About 10.5 ft | About 10.5 ft | Upgrading does not shorten the required throw. |
What you give up
What matters in practice
Treat Ultimate as an output upgrade within the same basic setup, not as a solution to an awkward projector position.
A larger picture spreads the available light across more surface. If you are still choosing the screen, the Ultimate gives you some additional rated output to work with. If the screen is already installed and looks appropriately bright, the advantage is less compelling than the model names suggest.
Both use fixed 1.2:1 optics. Upgrading does not allow a larger image from a shorter distance. Measure the lens position now, particularly when the only shelf is behind the sofa. Use physical placement to set image size wherever possible, then apply only the correction the room actually requires.
Amazon packages may differ in stands, glasses or other accessories. Compare the complete items you would otherwise need to buy, while keeping the projector names straight. Neither the included Google TV system nor the published 20W speaker rating makes the Ultimate a different kind of everyday streaming device.
What the facts say
Useful conclusions from the current home projectors comparison, followed by the checked facts used to reach them.
Only 17 of 90 models checked match every need here: “I mostly watch movies in a dark room”, “I want a picture 120 inches or larger”, and “I want Netflix ready on day one”.
17 matching models from 90 checkedJMGO N1S Ultimate lists 3,300 ISO lm for published ISO brightness, 18% above JMGO N1S Ultra at 2,800 ISO lm.
Match countThe count uses the current product-to-need assignments for “I mostly watch movies in a dark room”, “I want a picture 120 inches or larger”, and “I want Netflix ready on day one”. A need with no documented match does not count.
Calculation noteOnly ISO-lumen figures are included. ANSI and manufacturer-only lumen labels are kept out of this median. 44 of 90 models have comparable published figures for context.
