Main trade-off
Epson Home Cinema LS11000
Its minimum throw is too long for the stated 3.2m, 120-inch setup.
Head-to-head
Epson LS11000 vs BenQ X3100i: Epson accepts 4K120, BenQ reaches 240 Hz at 1080p
The short answer
Choose LS11000 for a farther-back installation, motorized lens adjustments or a 4K120 source. Choose X3100i when a shorter room, included streaming dongle and built-in speakers make temporary setup easier, or when a compatible PC will use 1080p240. The choice depends on the installation and signal you will actually use, rather than treating every high-refresh claim as the same experience.
Before you choose
The reasoning and the trade-offs
A rear shelf and a small room lead to opposite choices
A 120-inch 16:9 screen is about 2.66m wide. LS11000's throw range needs roughly 3.59 to 7.55m from lens to screen, while X3100i needs about 3.05 to 3.98m.
What this is based on
Screen width is 2.6566m. Multiply by 1.35 and 2.84 for Epson, or 1.15 and 1.50 for BenQ. Allow chassis and cable clearance separately.
Main trade-off
BenQ X3100i

About this comparison
Compare Epson LS11000 and BenQ X3100i for a rear shelf, 4K120 gaming, lens memories and an easier temporary movie-room setup.

Winner by situation
Start with what you need it to do
Keep a 5m rear shelf for a 120-inch screen
Only Epson's throw range includes the stated lens position.
- Epson Home Cinema LS11000
- Better fit
- BenQ X3100i
- Not suitable
Use a fixed 3.2m lens position for 120 inches
BenQ's shorter throw fits that geometry.

What matters in practice
The differences that matter
A rear shelf and a small room lead to opposite choices
A 120-inch 16:9 screen is about 2.66m wide. LS11000's throw range needs roughly 3.59 to 7.55m from lens to screen, while X3100i needs about 3.05 to 3.98m.
How we reached this conclusion
Screen width is 2.6566m. Multiply by 1.35 and 2.84 for Epson, or 1.15 and 1.50 for BenQ. Allow chassis and cable clearance separately.
Decide whether setup convenience means recalling a lens or carrying fewer boxes
In a permanent room, LS11000's motorized lens memories can restore saved zoom, focus and shift settings when switching an established screen arrangement. X3100i instead includes a streaming dongle and small speakers, which can simplify a temporary evening setup without a separate audio system.
How we reached this conclusion
The distinction uses Epson's documented motorized lens memories and BenQ's included QS02 plus two 5W speakers. Lens memories do not guarantee automatic calibration after moving furniture.
4K120 and 1080p240 are different purchases
A 4K120 console brief favors LS11000. X3100i's fastest documented timing is 1080p240, and its 1440p modes are downscaled to 1080p.
How we reached this conclusion
BenQ's exact compatibility table distinguishes 4K60, 1080p240 and downscaled 1440p input. Epson specifies 4K120.

Meaningful differences
What changes the fit
| What changes | Epson Home Cinema LS11000 | BenQ X3100i | Why it matters |
|---|---|---|---|
| Throw range | 1.35 to 2.84 | 1.15 to 1.50 | LS11000 reaches much farther rear shelf positions for the same image. |
| Lens operation | Motorized zoom, focus and shift with lens memories | Manual optical zoom and vertical lens shift | LS11000 is better suited to recalling an established lens setup. |
| High-refresh source modes | Up to 4K120 | 4K60 or 1080p240 | Choose around source resolution and refresh together. |
| Streaming and temporary audio | Plan an external source and audio system | QS02 Android TV dongle and two 5W speakers included | X3100i supplies more of a basic movie setup in the box. |
What you give up
Every choice has a cost
If you choose Epson Home Cinema LS11000
- A source device and audio system are separate parts of the installation.
If you choose BenQ X3100i
- Manual lens controls do not offer Epson's saved motorized lens positions.
Recommendation switch
The decision flips if...
The source must remain 4K at 120Hz
Choose Epson Home Cinema LS11000. LS11000 supports the required resolution and refresh combination.
A 3.2m lens position and included basic audio define the room
Choose BenQ X3100i. X3100i fits the stated 120-inch geometry and includes speakers.
What matters in practice
How to make the call
Choose LS11000 for a farther-back installation, motorized lens adjustments or a 4K120 source.
A rear shelf and a small room lead to opposite choices
A 120-inch 16:9 screen is about 2.66m wide. LS11000's throw range needs roughly 3.59 to 7.55m from lens to screen, while X3100i needs about 3.05 to 3.98m. Choose Epson for an existing 5m rear shelf. Choose BenQ for a fixed 3.2m lens position. Lens shift moves the image within its envelope, but it does not replace the required throw distance.
Decide whether setup convenience means recalling a lens or carrying fewer boxes
In a permanent room, LS11000's motorized lens memories can restore saved zoom, focus and shift settings when switching an established screen arrangement. X3100i instead includes a streaming dongle and small speakers, which can simplify a temporary evening setup without a separate audio system. Choose Epson for repeatable installed optics. Choose BenQ for the basic source-and-audio package. Moving either projector still requires checking image geometry, ventilation and available outlets.
4K120 and 1080p240 are different purchases
A 4K120 console brief favors LS11000. X3100i's fastest documented timing is 1080p240, and its 1440p modes are downscaled to 1080p. Do not buy it expecting native 1440p120 or 4K120 merely because the refresh number is high.
