Main trade-off
XGIMI Elfin Flip 4K
The 1 ms claim requires 1080p120, Game Mode, VRR on and auto keystone off. The maximum brightness mode may increase fan noise.
Head-to-head
Choose Elfin Flip 4K for a short, fixed table or a console plus an eARC-only soundbar. Choose the 1,700-lumen N1S 4K Upgrade for compatible 3D movies, or a lower current offer when its fixed throw fits. Check the source format and glasses. JMGO has one shared HDMI/eARC socket, so an external player also needs a workable sound connection.
Before you choose
With built-in Google TV, JMGO can send streaming sound through its one HDMI/eARC connection to a soundbar. Add a console and that socket is already occupied. If the soundbar has no separate HDMI input, the two cannot both connect directly. Elfin gives the soundbar HDMI1 and the console HDMI2. A compatible soundbar or receiver with video passthrough can make JMGO workable, but that is an equipment check before buying. Two consoles plus the soundbar exceed Elfin’s direct socket count too.
What this is based on
Port allocation derived from the current exact-model port lists. Assumes an eARC-only soundbar with no HDMI input. Passthrough is conditional on the receiving equipment and supported video/audio formats.

Main trade-off
One shared HDMI/eARC socket cannot directly connect a console and an eARC-only soundbar together. Its gimbal changes aim, not optical image size.


Compare Elfin Flip 4K and the 1700-lumen N1S 4K Upgrade for a small living room, a console plus soundbar and a projector you put away after watching.
These compact triple-laser 4K Google TV projectors compete for movie nights in rooms without a permanent installation. Elfin’s optical zoom and extra HDMI port can matter more than a small difference between their brightness claims.
Winner by situation
Elfin can fit that image optically. JMGO needs a farther lens position.
JMGO supports 3D. Elfin explicitly does not. An external player also needs a sound-system connection plan.
Elfin has two sockets. JMGO has one shared HDMI/eARC socket.
Both have Google TV. If the current JMGO offer is lower, the extra Elfin flexibility may add little to this setup.
Three direct connections exceed both documented port counts.

At 9.5 feet, JMGO’s fixed 1.2 throw makes a maximum picture of roughly 109 inches before digital correction. It cannot fill a 120-inch screen from there. Elfin’s optical zoom can. That matters when a sofa, walkway or small dining area prevents moving the table back. If you can use about 10.5 feet, both can make 120 inches and JMGO’s simpler fixed lens stops being a meaningful obstacle. Do not pay for optical flexibility you have no need to use.
At 9.5 ft, diagonal = 9.5 × 12 / 1.2 × √337 / 16 = 109.0 inches. A 120-inch 16:9 image needs about 10.46 ft at 1.2. No keystone, digital shrink or installation tolerance is included.
JMGO supports 3D while Elfin explicitly does not. If occasional 3D nights are the reason to keep a projector, Elfin’s extra socket cannot recover that missing capability. Check that the actual source format and glasses work with JMGO before buying. If an external player supplies those films, it also occupies the single HDMI socket. You may need the player’s separate audio output or compatible receiver passthrough to keep the existing sound system. A household that streams ordinary 2D films avoids that particular compromise and can give more weight to Elfin’s placement flexibility.
A documented feature exclusion crossed with a conditional external-player and sound-system requirement. No universal compatibility with every 3D disc format, player, glasses or receiver is inferred.
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 range is about 8.54 to 11.33 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.

XGIMI, Elfin Flip 4K
Your 120-inch screen needs a lens around 9.5 feet away, within Elfin’s optical zoom range.

JMGO, N1S 4K Upgrade
You want 3D and have checked the source format, compatible glasses and sound connection. Elfin does not support 3D.
Meaningful differences
| What changes | XGIMI Elfin Flip 4K | JMGO N1S 4K | Why it matters |
|---|---|---|---|
| 120-inch optical position | About 8.5 to 11.3 feet | About 10.5 feet at fixed 1.2 throw | Elfin leaves more choice of table position while keeping the same picture size without digital shrinking. |
| Console plus eARC soundbar | Two HDMI ports, eARC on HDMI1 | One HDMI port, also used for eARC | The JMGO port is shared between jobs, not a second audio-only socket. |
| Streaming without an HDMI player | Google TV with native Netflix | Google TV with native Netflix | Built-in apps can avoid using the external-input socket. Check the specific service and subscription. |
| 3D movie nights | 3D explicitly excluded in XGIMI’s comparison table | 3D supported with compatible content and glasses | JMGO is the relevant choice for this requirement. Check the input format and accessories instead of assuming every 3D source works. |
| Aiming the image | Folding stand with optical zoom | 127-degree gimbal with fixed optical throw | A gimbal helps point the picture. It cannot enlarge a fixed-lens picture without moving farther away. |
| Published output | 1,600 ISO lumens | 1,700 ISO lumens for the Upgrade version | These are manufacturer claims, not a matched comparison of the viewing modes you will use. |
| Weight evidence | 1.55 kg body | Marketing says 4.4 lb while specifications say 2.2 kg | JMGO’s conflicting values are not used to calculate a precise weight or comfort advantage. |
What you give up
Recommendation switch
Choose XGIMI Elfin Flip 4K. Elfin supplies optical zoom and a second HDMI connection.
Choose JMGO N1S 4K. JMGO supports 3D with the source and glasses checked. Its one HDMI socket still needs a workable sound route.
Choose neither. Plan suitable switching or receiver equipment rather than expecting unused sockets.
What matters in practice
You want a compact projector to keep the room simple, but adding a console and the soundbar you already own can turn a one-box plan into an extra-hardware purchase.
