The catch
Epson Home Cinema LS11000
For the stated 3.2m, 120-inch setup, its minimum throw is too long.
Side by side
Epson LS11000 vs BenQ X3100i: BenQ reaches 240 Hz at 1080p, Epson accepts 4K120
Quick verdict
The LS11000 suits a farther-back installation, motorized lens adjustments or a 4K120 source. The X3100i suits a shorter room where the included streaming dongle and built-in speakers make a temporary setup easier, and it also suits a compatible PC running 1080p240. What matters is the installation and signal you will really use, since high-refresh claims do not all deliver the same experience.
Before you buy
Why, and what it costs you
A rear shelf and a small room point in opposite directions
At 120 inches, a 16:9 screen is about 2.66m wide. LS11000's throw range calls for roughly 3.59 to 7.55m from lens to screen, and X3100i for about 3.05 to 3.98m.
Where this comes from
The screen is 2.6566m wide. Multiply by 1.35 and 2.84 for Epson, or by 1.15 and 1.50 for BenQ. Chassis and cable clearance need to be allowed for separately.
The catch
BenQ X3100i
Its fastest refresh mode comes at the cost of 4K resolution.

In practice
Differences you will notice
A rear shelf and a small room point in opposite directions
At 120 inches, a 16:9 screen is about 2.66m wide. LS11000's throw range calls for roughly 3.59 to 7.55m from lens to screen, and X3100i for about 3.05 to 3.98m.
How we worked this out
The screen is 2.6566m wide. Multiply by 1.35 and 2.84 for Epson, or by 1.15 and 1.50 for BenQ. Chassis and cable clearance need to be allowed for separately.
Setup convenience can mean recalled lens settings or fewer boxes to carry
For a permanent room, LS11000's motorized lens memories can bring back saved zoom, focus and shift settings when you switch an established screen arrangement. X3100i comes instead with a streaming dongle and small speakers, which can make a temporary evening setup simpler with no separate audio system.
How we worked this out
This distinction rests on the motorized lens memories documented for Epson and the included QS02 plus two 5W speakers for BenQ. Lens memories do not guarantee automatic calibration after furniture is moved.
Buying for 4K120 differs from buying for 1080p240
For a console that has to run 4K120, LS11000 is the better fit. X3100i's fastest documented timing is 1080p240, and its 1440p modes are downscaled to 1080p.
How we worked this out
In BenQ's exact compatibility table, 4K60, 1080p240 and downscaled 1440p input are listed separately. Epson specifies 4K120.

| Spec | Epson Home Cinema LS11000 | BenQ X3100i | In practice |
|---|---|---|---|
| Throw range | 1.35 to 2.84 | 1.15 to 1.50 | For the same image, LS11000 can sit on a rear shelf much farther back. |
| Lens operation | Motorized zoom, focus and shift with lens memories | Manual optical zoom and vertical lens shift | Recalling an established lens setup is something LS11000 handles better. |
| High-refresh source modes | Up to 4K120 | 4K60 or 1080p240 | Pick based on source resolution and refresh rate taken together. |

Trade-offs
What each pick costs you
With Epson Home Cinema LS11000
- The installation has a source device and an audio system as separate parts.
With BenQ X3100i
- Epson's saved motorized lens positions have no counterpart in manual lens controls.
Change of plan
When the answer changes
The source has to stay at 4K and 120Hz
Go with Epson Home Cinema LS11000. The required combination of resolution and refresh is supported by LS11000.
The room is defined by a 3.2m lens position and included basic audio
Go with BenQ X3100i. X3100i suits the stated 120-inch geometry and has speakers included.
Decision guide
How to decide
The LS11000 is the pick for a farther-back installation, motorized lens adjustments or a 4K120 source.
A rear shelf and a small room point in opposite directions
At 120 inches and 16:9, the screen is about 2.66m wide. From lens to screen, the LS11000's throw range calls for roughly 3.59 to 7.55m, compared with about 3.05 to 3.98m for the X3100i. An existing 5m rear shelf points to the Epson, and a fixed 3.2m lens position points to the BenQ. Lens shift moves the image inside its envelope but cannot stand in for the required throw distance.
Setup convenience can mean recalled lens settings or fewer boxes to carry
In a permanent room, the LS11000's motorized lens memories bring back saved zoom, focus and shift settings when you change between established screen arrangements. The X3100i takes another route. It includes a streaming dongle and small speakers, which can make a temporary evening setup simpler without a separate audio system. Epson is the choice for repeatable installed optics, and BenQ for the basic source-and-audio package. With either one, moving the projector still means checking image geometry, ventilation and available outlets.
Buying for 4K120 differs from buying for 1080p240
If your console needs 4K120, that favors the LS11000. The fastest documented timing on the X3100i is 1080p240, and its 1440p modes are downscaled to 1080p. A high refresh number is no reason to buy it expecting native 1440p120 or 4K120.
