Main trade-off
BenQ TK710
Its color coverage tops out around Rec.709 rather than the wider cinema gamuts of premium RGB-laser models.
Head-to-head
BenQ TK710 vs TK710STi: STi fits closer, TK710 adds vertical lens shift
The short answer
Choose the TK710STi if you need a large picture from a short distance. Choose the TK710 for a mount farther back or when vertical lens shift would help align the image. Their published brightness and main gaming response figures are tied, so the lens should decide this purchase.
Before you choose
The reasoning and the trade-offs
A 120-inch screen leaves two separate placement bands
The TK710STi fits at about 6.0–7.2 feet. The TK710 fits at about 10.0–13.1 feet. A lens fixed at eight feet is outside both optical bands.
What this is based on
A 120-inch 16:9 image is 104.6 inches wide. Multiply that width by each throw-ratio endpoint and divide by 12 to get feet. No digital zoom or keystone is included.
Main trade-off
BenQ TK710STi
It has no optical lens shift, so the short throw still needs a centered shelf or mount.
BenQ TK710
- Choose it for
- Your 120-inch screen sits roughly 10 to 13 feet from the lens.
- You want vertical lens shift for a fixed installation.
- Main trade-off
- Its color coverage tops out around Rec.709 rather than the wider cinema gamuts of premium RGB-laser models.
BenQ TK710STi
- Choose it for
- Your 120-inch screen sits roughly 6 to 7 feet from the lens.
- You want the included Android TV streaming device.
- Main trade-off
- It has no optical lens shift, so the short throw still needs a centered shelf or mount.
About this comparison
Compare BenQ TK710 and TK710STi by the distance needed for your screen, lens adjustment, streaming and gaming. A 120-inch room-fit example makes the choice clear.
The short-throw lens changes where you can put the projector. It does not buy a higher published brightness or a faster 4K60 response.
Winner by situation
Start with what you need it to do
A 120-inch picture from a 6.5-foot lens position
Only the STi's optical range includes this position.

- Better fit
A 120-inch picture from an 11-foot rear mount
The standard TK710 reaches this size optically from the rear of the room.

What matters in practice
The differences that matter
A 120-inch screen leaves two separate placement bands
The TK710STi fits at about 6.0–7.2 feet. The TK710 fits at about 10.0–13.1 feet. A lens fixed at eight feet is outside both optical bands.
How we reached this conclusion
A 120-inch 16:9 image is 104.6 inches wide. Multiply that width by each throw-ratio endpoint and divide by 12 to get feet. No digital zoom or keystone is included.
The shortest placement is 40% closer
At the wide end of each lens, the STi needs 40% less throw distance for the same picture width. This helps keep the projector in front of seating, but body depth and cable space still matter.
How we reached this conclusion
1 minus 0.69 divided by 1.15 equals 0.40. The comparison concerns lens-to-screen distance only.
Gaming specifications do not explain the price gap
Both publish 16.7 ms at 4K60 and 4.2 ms at 1080p240. Choose the lens that works first, then the streaming bundle.
How we reached this conclusion
The exact BenQ specification tables use the same input formats for these latency values. They are manufacturer claims, not independent measurements.

BenQ TK710
Does not fit these inputsFor a 120-inch 16:9 picture, the calculated lens range is about 10.02 to 13.07 ft. Your input is 9.50 ft.
BenQ TK710STi
Does not fit these inputsFor a 120-inch 16:9 picture, the calculated lens range is about 6.01 to 7.23 ft. Your input is 9.50 ft.
Distance is measured from the lens to the screen. The calculation uses a 16:9 image and the verified optical throw range for each exact model.

Meaningful differences
What changes the fit
| What changes | BenQ TK710 | BenQ TK710STi | Why it matters |
|---|---|---|---|
| Throw ratio | 1.15–1.50:1 | 0.69–0.83:1 | The STi needs substantially less room between the lens and screen. |
| 120-inch optical distance | 10.0–13.1 ft | 6.0–7.2 ft | There is no shared mounting distance for this picture size. |
| Optical zoom | 1.3x | 1.2x | The standard model has a wider adjustment range around its longer throw. |
| Vertical lens shift | +10% | No lens shift listed | The TK710 offers optical height adjustment before resorting to keystone. |
| Streaming | External device required | Android TV device included | Account for an additional streamer when comparing complete packages. |
| Brightness and 4K60 response | 3,200 ANSI lumens, 16.7 ms | 3,200 ANSI lumens, 16.7 ms | These published specifications do not separate the pair. |
What you give up
Every choice has a cost
If you choose BenQ TK710
- It lacks a built-in smart platform, and independent testing found only average black levels and imperfect out-of-box color.
If you choose BenQ TK710STi
- Its Rec.709-focused color is less expansive than RGB-laser and cinema-first wide-gamut models.
What matters in practice
How to make the call
Measure from the lens to the screen before comparing features. These two lenses serve different positions in the room.
The mounting point can settle the choice
A projector shelf behind a sofa and a coffee table in front of it are very different starting points. Work out the desired picture size, then check the matching distance range. Buying the wrong lens and shrinking the picture digitally leaves you paying for pixels you are no longer using.
Keep the image square at the source
The TK710 gives you vertical lens shift, useful when the mount cannot sit at the ideal height. The short-throw model requires closer attention to its fixed optical offset. Place either unit straight toward the screen before using digital corrections, particularly for gaming and small text.
Budget for the rest of the setup
The TK710STi includes an Android TV device. The TK710 needs a separate streaming source if you do not already own one. Both can take a console over HDMI. Check the number of sources you need and how sound will reach your speakers before treating the projector alone as the complete system.
What this comparison cannot tell you
- Distances assume a flat 16:9 screen and optical sizing without digital shrink.
- Manufacturer latency figures apply to the stated input format and operating mode.
