The catch
XGIMI Elfin Flip 4K
It has no battery, and brightness was mediocre in independent testing, which makes it best after dark.
Side by side
If you move the projector often or want Google TV, the Elfin Flip 4K is the better fit. The M2 Pro fits if Dolby Vision and its VIDAA apps suit your viewing. Either projector can make a 120-inch picture optically from 9.5 feet, so the small difference in minimum throw shouldn't decide most purchases.
Before you buy
For a 120-inch picture, the useful range of the two lenses is nearly identical.
Where this comes from
At 120 inches, a 16:9 image is 104.59 inches wide. (1.00 - 0.98) × 104.59 = 2.09 inches. The maximum ratio is 1.3 for both.
The catch
It has no battery, and brightness was mediocre in independent testing, which makes it best after dark.
The catch
Both the 1,300 ANSI-lumen rating and the tested contrast are modest compared with larger lifestyle models.

Elfin Flip 4K and Hisense M2 Pro weighed for a 120-inch room, carrying weight, streaming and HDR. Their lens ranges are closer than they appear.
If you move the projector often or want Google TV, the Elfin Flip 4K is the better fit. The M2 Pro fits if Dolby Vision and its VIDAA apps suit your viewing. Either projector can make a 120-inch picture optically from 9.5 feet, so the small difference in minimum throw shouldn't decide most purchases.
Which one fits
Getting a 16:9 picture of 120 inches from 9.5 feet takes a throw ratio of about 1.09, and the optical ranges of both projectors include it.
The Elfin body, at 1.55 kg, is 2.35 kg lighter than the 3.9 kg M2 Pro. External power is required for both.
Dolby Vision works on the M2 Pro. It is not part of the HDR support listed for the Elfin Flip 4K.
Google TV is on the Elfin. The M2 Pro runs VIDAA, so confirm the exact apps you watch before settling on its built-in platform.
In practice
For a 120-inch picture, the useful range of the two lenses is nearly identical.
At 120 inches, a 16:9 image is 104.59 inches wide. (1.00 - 0.98) × 104.59 = 2.09 inches. The maximum ratio is 1.3 for both.
That is 2.35 kg less projector body to lift.
3.9 - 1.55 = 2.35 kg, and 2.35 ÷ 3.9 = 60.3%. Adapters, cables and cases are not counted.
You can decide on carrying and streaming needs and leave that lens position where it is.
9.5 × 12 ÷ 104.59 = 1.09 is the required throw ratio, which sits inside both published optical ranges.
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 range is about 8.54 to 11.33 ft. You entered 9.50 ft.
For a 120-inch 16:9 picture, the calculated lens range is about 8.72 to 11.33 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.

|---|---|---|---|
| 120-inch lens distance | About 8.5 to 11.3 ft | About 8.7 to 11.3 ft | A lens position 9.5 feet from a 120-inch screen is covered by both. |
| Published throw ratio | 0.98 to 1.3 | 1.0 to 1.3 | Between the two, the nearer limit at 120 inches differs by only about 2.1 inches. |
| Listed product weight | 1.55 kg | 3.9 kg | Before either power adapter is added, the Elfin body is 2.35 kg lighter. |
| HDR formats | HDR10 and HLG | Dolby Vision, HDR10 and HLG | If Dolby Vision matters, the M2 Pro is the one that supports it here. |
| Smart platform | Google TV | VIDAA | Check the apps you really use instead of assuming all smart projectors are the same. |
| Published brightness | 1600 ISO lumens | 1300 ANSI lumens | A direct numerical brightness ranking is not possible because the measurement labels differ. |
Trade-offs
Decision guide
The Elfin Flip 4K is the choice if you move the projector often or want Google TV. If Dolby Vision and its VIDAA apps fit your viewing, choose the M2 Pro. From 9.5 feet, both can make a 120-inch picture optically, so the small difference in minimum throw shouldn't drive most purchases.
On a spec sheet, minimum ratios of 0.98 and 1.0 can look like different classes. For a 120-inch 16:9 image, though, the nearest lens position shifts by only about two inches. Leave some installation tolerance rather than relying on either boundary exactly.
Once placed, both are easy to size thanks to optical zoom. Lifting them is a different task. The Elfin's published body weight is much lower, which matters if it comes off the shelf after every movie.
Dolby Vision is supported by the M2 Pro, whereas the Elfin lists HDR10 and HLG. The app selections on Google TV and VIDAA differ as well. Check the services and formats you use, and then compare the current Amazon offers in the same condition.
