The catch
BenQ X3100i
Most lifestyle models are far less bulky than this tall 15-pound chassis.
Side by side
BenQ X3100i vs ViewSonic LX700-4K compared: ViewSonic fits closer, BenQ includes streaming
Quick verdict
Go for the X3100i if you want its 4LED gaming design and included streaming device. The LX700-4K is the better match for a closer laser installation that uses your own HDMI sources.
Before you buy
Why, and what it costs you
Confirm a 120-inch picture fits first
For a 120-inch 16:9 picture, expect 10 to 13.1 ft from lens to screen with the BenQ X3100i and 9.2 to 12.6 ft with the ViewSonic LX700-4K.
Where this comes from
Width = diagonal × 16 / √337, which is 104.6 inches at 120 inches. Times each documented throw endpoint, divided by 12, that gives feet. Digital zoom, keystone, cabinet offset and lens-shift limits are not included.
The catch
ViewSonic LX700-4K
Out-of-box color and gamma were inaccurate according to ProjectorCentral, which may steer buyers who put movies first toward a cinema model.

You'd find an included streaming device useful
A licensed Android TV device comes with the X3100i. The LX700-4K needs an external streamer, which brings its own power and cable arrangement.

The projector has to sit closer
At a 120-inch picture, the LX700-4K's minimum lens distance is about nine inches shorter, since it starts at a 1.06 throw against 1.15 for the X3100i.

Taking the lens as the starting point, allow 10 to 13.1 ft for the BenQ X3100i or 9.2 to 12.6 ft for the ViewSonic LX700-4K. Check cabinet and mounting clearances on their own.

In practice
Differences you will notice
Confirm a 120-inch picture fits first
For a 120-inch 16:9 picture, expect 10 to 13.1 ft from lens to screen with the BenQ X3100i and 9.2 to 12.6 ft with the ViewSonic LX700-4K.
How we worked this out
Width = diagonal × 16 / √337, which is 104.6 inches at 120 inches. Times each documented throw endpoint, divided by 12, that gives feet. Digital zoom, keystone, cabinet offset and lens-shift limits are not included.
Treat the light ratings with their limits in mind
The BenQ X3100i lists 3300 ANSI lumens and the ViewSonic LX700-4K lists 3500, which makes the higher headline about 6% above the lower one. These ratings come from the manufacturers and are not matched measurements.
How we worked this out
Published exactly, the inputs are 3300 ANSI for BenQ X3100i and 3500 ANSI for ViewSonic LX700-4K. A percentage is shown only when the labeled standard matches. Manufacturer methods, calibration and picture modes can still differ.
Don't let a small brightness headline outweigh the package
The X3100i includes the streaming device that ViewSonic leaves to the buyer, while the LX700-4K's listed ANSI output is only about 6% higher than the X3100i's.
How we worked this out
(3500 / 3300 - 1) × 100 = 6.1%. Android TV is part of the X3100i package, whereas the LX700-4K has no built-in streaming platform.
Plug in your numbers
Will either projector work in your room?
This checks hard limits only. Personal preferences are left out of the math.
BenQ X3100i
Does not work with your numbersFor a 120-inch 16:9 picture, the calculated lens range is about 10.02 to 13.07 ft. You entered 9.50 ft.
ViewSonic LX700-4K
Works with your numbersFor a 120-inch 16:9 picture, the calculated lens range is about 9.24 to 12.64 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.

Spec by spec
Where they really differ
| Spec | BenQ X3100i | ViewSonic LX700-4K | In practice |
|---|---|---|---|
| Optical throw ratio | 1.15 to 1.5 | 1.06 to 1.45 | Distance runs from the lens to the screen and is calculated from the image width. |
| Lens distance for 120 inches | 10 to 13.1 ft | 9.2 to 12.6 ft | The calculation assumes 16:9 and optical adjustment alone. Cabinet depth and cable clearance come on top. |
| Published image-size range | 30 to 300 in | 30 to 300 in | A supported maximum is no guarantee of a bright picture in your room. |
| Published light output | 3300 ANSI lumens | 3500 ANSI lumens | You cannot swap one measurement standard or picture mode for another. |
| Display architecture | single-chip-dlp | single-chip-dlp | Viewers who are sensitive to rainbow flashes may care about single-chip sequential color. |
| Streaming platform | Included Android TV device | None | Before you add a separate streamer, confirm the exact US edition and the apps you need. |
Trade-offs
What each pick costs you
With BenQ X3100i
- In independent testing, dark-scene contrast was weaker, and 1440p input was noted as being downscaled internally.
With ViewSonic LX700-4K
- There's no smart OS, 4K120 input isn't supported, and the single speaker sounds thin.
Decision guide
How to decide
The X3100i is the pick for its 4LED gaming design and included streaming device. LX700-4K fits a closer laser installation with your own HDMI sources.
ViewSonic wins on the closer position
The LX700-4K starts at a 1.06 throw, versus 1.15 for the X3100i. At a 120-inch picture that difference saves about nine inches, which can matter at the edge of a room.
The included device alters the complete package
A licensed Android TV device comes with the X3100i, but the LX700-4K requires an external streamer. That's a small detail until there's no spare outlet or cable route.
The headline brightness gap is small
Published ANSI figures of 3,300 and 3,500 are only about six percent apart. With no matched picture-mode tests, light-source preference and fit tell you more than a declared brightness winner would.
What this page can’t tell you
- Throw calculations rely on published optical ranges and a 16:9 picture, so they can't stand in for the exact installation diagram.
- Published lumens, contrast and latency don't amount to a matched real-room picture-quality result.
