Main trade-off
JMGO N1S 4K
The 1,700 ISO-lumen rating is far below the N1S Ultimate and N3 Ultimate, so it is better after dark.
Head-to-head
Choose the N1S 4K for dark-room streaming and occasional ceiling viewing. Choose the N1S Ultra when the image must hold up in a brighter room or at a larger size. Both use a fixed 1.2 throw, so neither solves a tight shelf with optical zoom.
Before you choose
For “ISO brightness”, the published figure is 65% higher for JMGO N1S Ultra, at 2,800 ISO lumens compared with 1,700 ISO lumens for JMGO N1S 4K.
What this is based on
The published output matters only when the room, surface or workload needs the extra headroom. It does not prove better results by itself. The percentage uses the lower published figure as the baseline.
Main trade-off

Main trade-off
Its fixed throw ratio means the gimbal changes aim but not image size from a given distance.


Compare two 4K Google TV gimbal projectors by brightness, room use and the features that remain identical.
The practical choice turns on published iso brightness, then on the constraints in your own setup.
Winner by situation
Its documented light output is sized for moderate room light. A suitable screen and controlled daylight still matter.
Its integrated speakers are useful for casual viewing without adding a soundbar immediately.
Its weight, handle, gimbal or integrated stand makes room-to-room use more practical.
Both records list “Gimbal, Google TV and native Netflix” for shared convenience. Both records show the same result for “Shared convenience”, so this row does not separate them.
Its compact body, close-focusing optics or flexible stand makes an 80–120-inch image more practical in a tighter room.
Its documented game mode reduces input delay, with high-refresh support counted when the exact model provides it.
