The catch
Optoma UHD35STx
Calculate the mount position before buying, since the 0.5 throw lens is fixed.
Side by side
Optoma UHD35STx vs BenQ TK710STi: BenQ adds optical zoom, Optoma fits closer
Quick verdict
The UHD35STx is the pick when the projector must sit as close as possible in a fixed spot. The TK710STi fits a laser setup that needs optical zoom and streaming included.
Before you buy
Why, and what it costs you
Confirm a 120-inch picture fits first
For a 120-inch 16:9 picture the lens sits 4.4 ft from the screen with the Optoma UHD35STx, versus 6 to 7.2 ft with the BenQ TK710STi.
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
BenQ TK710STi
Without optical lens shift, even the short throw requires a shelf or mount that's centered.

What this page compares
The TK710STi is the laser option here, with optical zoom and streaming included. The UHD35STx is the pick when the projector has to sit as close as possible in a fixed spot.

Which one fits
Pick the situations that sound like you
The projector has to be placed very close
Throw is fixed at 0.5 on the Optoma and 0.69 to 0.83 on the BenQ. At 120 inches, the Optoma sits about 4.4 feet back, where the BenQ needs six to seven feet.

You need some optical adjustment range at the mount
The TK710STi offers an optical throw range of 0.69 to 0.83. The UHD35STx is fixed at 0.5, so getting the mounting distance right is what counts, since there is no optical zoom to adjust.

Counting from the lens, allow 4.4 ft for the Optoma UHD35STx or 6 to 7.2 ft for the BenQ TK710STi. Cabinet and mounting clearances need their own check.

Differences you will notice
Confirm a 120-inch picture fits first
For a 120-inch 16:9 picture the lens sits 4.4 ft from the screen with the Optoma UHD35STx, versus 6 to 7.2 ft with the BenQ TK710STi.
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 Optoma UHD35STx is listed at 3600 published lumens and the BenQ TK710STi at 3200 ANSI. The labeled standards differ, so no brightness multiplier is derived from them.
How we worked this out
The exact published inputs are 3600 published for Optoma UHD35STx and 3200 ANSI for BenQ TK710STi. Percentages are shown only for figures with the same labeled standard, and manufacturer methods, calibration and picture modes can still differ.
Choosing the shortest throw is not the same as choosing the more adjustable lens
At its nearest setting, UHD35STx can sit about 28% closer than TK710STi. TK710STi, though, supplies optical zoom and a laser light source.
How we worked this out
1 - 0.5 / 0.69 = 27.5%. Optoma has a fixed 0.5 throw and a lamp. BenQ runs 0.69 to 0.83 and uses a laser.

Spec by spec
Where they really differ
| Spec | Optoma UHD35STx | BenQ TK710STi | In practice |
|---|---|---|---|
| Optical throw ratio | 0.5 to 0.5 | 0.69 to 0.83 | Distance runs from the lens to the screen and is calculated from the image width. |
| Lens distance for 120 inches | 4.4 ft | 6 to 7.2 ft | The calculation assumes 16:9 and optical adjustment alone. Cabinet depth and cable clearance come on top. |
| Published image-size range | 36.43 to 300.53 in | 30 to 300 in | A supported maximum is no guarantee of a bright picture in your room. |
| Published light output | 3600 published lumens | 3200 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 | None | Included Android TV device | Before you add a separate streamer, confirm the exact US edition and the apps you need. |
Trade-offs
What each pick costs you
With Optoma UHD35STx
- The lamp is replaceable, and there's no smart streaming platform.
With BenQ TK710STi
- Color is built around Rec.709, which covers less than RGB-laser and cinema-first wide-gamut models.
Decision guide
How to decide
Take the UHD35STx if the shortest fixed position matters most in this pair. Take the TK710STi for a laser installation that also needs optical zoom and included streaming.
A short throw can be a firm requirement
Throw is fixed at 0.5 on the Optoma and 0.69 to 0.83 on the BenQ. At 120 inches, the Optoma sits about 4.4 feet back, where the BenQ needs six to seven feet.
A lamp or a laser changes what upkeep looks like
The TK710STi runs on a laser and comes with an Android TV device, whereas the UHD35STx uses a lamp. For people who watch movies often, that changes what the whole purchase involves.
Only the BenQ has optical zoom to work with
With a fixed lens, exactly where the projector sits becomes critical. The BenQ can change the image size optically within its range. The Optoma needs you to move the unit or resort to digital adjustment.
What this page can’t tell you
- Treat the throw math as a guide. It rests on published optical ranges and a 16:9 picture, so the exact installation diagram still has the final say.
- Lumens, contrast and latency figures from the spec sheets do not prove how the two would look side by side in an actual room.
