The catch
LG CineBeam S
Controlled light is needed for the 500 ANSI-lumen output, which works best at the smaller end of its range.
Side by side
XGIMI MIRA vs LG CineBeam S: MIRA needs at least 80, LG starts at 40 inches
Quick verdict
For a small UST picture down to 40 inches, choose the CineBeam S. The MIRA fits an 80 to 120-inch living-room screen with Google TV.
Before you buy
Why, and what it costs you
Check a 100-inch picture fits before you choose
A 100-inch 16:9 picture needs 1.8 ft from lens to screen with the LG CineBeam S and 1.3 ft with the XGIMI MIRA.
Where this comes from
Width = diagonal × 16 / √337, so a 100-inch diagonal gives 87.2 inches. Times each documented throw endpoint, divided by 12, that gives feet. Digital zoom, keystone, cabinet offset and lens-shift limits are left out.
The catch
XGIMI MIRA
Larger premium UST models are more flexible than its fixed 80 to 120-inch range.

Which one fits
Pick the situations that sound like you
The picture you plan is 40 to 79 inches
LG covers 40 to 100 inches and MIRA covers 80 to 120. For a 60-inch plan, LG is the match, and for a 110-inch plan, MIRA is.
- LG CineBeam S
- Better fit
- XGIMI MIRA
- Not suitable
The screen size is over 100 and up to 120 inches
MIRA handles pictures up to 120 inches, but CineBeam S tops out at 100 in the published range, so LG cannot meet this larger-screen requirement.

I've settled on a 100-inch 16:9 screen
Measured from the lens, 1.8 ft applies to the LG CineBeam S and 1.3 ft to the XGIMI MIRA. Cabinet and mounting clearances need a separate check.

The LG CineBeam S is documented with webOS and the XGIMI MIRA with Smart platform. Verify the exact US model and the apps you need, and do not rely on a similar name or older generation.

In practice
Differences you will notice
Check a 100-inch picture fits before you choose
A 100-inch 16:9 picture needs 1.8 ft from lens to screen with the LG CineBeam S and 1.3 ft with the XGIMI MIRA.
How we worked this out
Width = diagonal × 16 / √337, so a 100-inch diagonal gives 87.2 inches. Times each documented throw endpoint, divided by 12, that gives feet. Digital zoom, keystone, cabinet offset and lens-shift limits are left out.
Treat the light ratings with their limits in mind
The LG CineBeam S lists 500 ANSI lumens and the XGIMI MIRA lists 2000 ISO. Different labeled standards are not converted into a brightness multiplier here.
How we worked this out
Exact inputs, as published: 500 ANSI for LG CineBeam S and 2000 ISO for XGIMI MIRA. A percentage is shown only when the labeled standard is the same. Manufacturer methods, calibration and picture modes can still differ.
Your intended picture size may settle this straight away
The overlap between CineBeam S and MIRA is just 80 to 100 inches. Outside that band, one of the two models is beyond its published image-size range.
How we worked this out
LG covers 40 to 100 inches and MIRA 80 to 120 inches, so the intersection is 80 to 100. The check applies to published optical use limits and not to subjective picture quality.
Plug in your numbers
Will either projector work in your room?
This checks hard limits only. Personal preferences are left out of the math.
LG CineBeam S
Does not work with your numbersFor a 120-inch 16:9 picture, the calculated lens position is about 2.18 ft. You entered 9.50 ft. This model is documented for pictures from 40 to 100 inches.
XGIMI MIRA
Does not work with your numbersFor a 120-inch 16:9 picture, the calculated lens position is about 1.53 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.
With an ultra-short-throw model, the gap behind the cabinet is a separate measurement. Check the installation diagram for cabinet position, screen height and ventilation.

Spec by spec
Where they really differ
| Spec | LG CineBeam S | XGIMI MIRA | In practice |
|---|---|---|---|
| Optical throw ratio | 0.25 to 0.25 | 0.175 to 0.175 | Distance runs from the lens to the screen and is calculated from the image width. |
| Lens distance for 100 inches | 1.8 ft | 1.3 ft | The calculation assumes 16:9 and optical adjustment alone. Cabinet depth and cable clearance come on top. |
| Published image-size range | 40 to 100 in | 80 to 120 in | A supported maximum is no guarantee of a bright picture in your room. |
| Published light output | 500 ANSI lumens | 2000 ISO 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 | webOS | Smart platform | Before you add a separate streamer, confirm the exact US edition and the apps you need. |
Trade-offs
What each pick costs you
With LG CineBeam S
- Stock on the verified new-model Amazon page is currently limited, and there's no battery.
With XGIMI MIRA
- A compact body doesn't remove the need for precise cabinet height and a flat wall or screen.
Decision guide
How to decide
CineBeam S suits a small UST picture down to 40 inches. MIRA is for an 80 to 120-inch living-room screen with Google TV.
Their supported size ranges overlap only in part
LG covers 40 to 100 inches and MIRA covers 80 to 120. For a 60-inch plan, LG is the match, and for a 110-inch plan, MIRA is.
A shorter throw doesn't mean a smaller supported image
The MIRA has the shorter 0.175 throw, yet its minimum stated screen is bigger. When checking a room, use both the throw ratio and the supported image range.
Even a compact UST needs a flat surface and screen
Cabinet height has to be exact for either one, and the image surface must be flat. Take exact installation measurements first, since swapping in either projector for a TV may mean changing your furniture.
What this page can’t tell you
- The exact installation diagram is what to follow. The throw calculations here rest on published optical ranges and a 16:9 picture, so they cannot stand in for it.
- Spec-sheet lumens, contrast and latency numbers cannot show how the two compare for picture quality in the same real room.
