The catch
BenQ TK700
At minimum throw it takes roughly two more feet to make the same large image.
Side by side
BenQ TK700 vs BenQ TK700ST: TK700 fits 10–12 and ST fits 8–9 ft for 120 inches
Quick verdict
If the lens will sit around ten to twelve feet from a 120-inch screen, go with the TK700. If it will sit around eight to nine feet away, go with the TK700ST. Published 4K/60 latency is identical, so the short-throw model is worth the extra money only when it solves the room.
Before you buy
Why, and what it costs you
A small gap exists where neither model fills the screen optically
Neither model gets to exactly 120 inches within its optical range from a 9.6-foot lens position. The ST needs about 9.4 feet or less, and the TK700 starts around 9.8. A few inches of mount movement can count for more than a brightness specification.
Where this comes from
BenQ TK700: 120-inch 16:9 width 104.59 inches × 1.127 / 12 = 9.82 feet minimum. BenQ TK700ST: 104.59 × 1.08 / 12 = 9.41 feet maximum. Optical gap about 4.9 inches.
The catch
BenQ TK700ST
A rear shelf may be unusable at your chosen screen size because of its short lens.

What this page compares
The BenQ TK700 and TK700ST come down to which lens fits your room. Compare 120-inch throw distances, a fixed ceiling mount, lamp upkeep and console connections.
Which one fits
Pick the situations that sound like you
An eleven-foot lens position with a 120-inch screen
From eleven feet, the TK700 is the only one that reaches this size optically.

An eight-foot lens position with a 120-inch screen
The ST alone has the short optical throw required.

In practice
Differences you will notice
A small gap exists where neither model fills the screen optically
Neither model gets to exactly 120 inches within its optical range from a 9.6-foot lens position. The ST needs about 9.4 feet or less, and the TK700 starts around 9.8. A few inches of mount movement can count for more than a brightness specification.
How we worked this out
BenQ TK700: 120-inch 16:9 width 104.59 inches × 1.127 / 12 = 9.82 feet minimum. BenQ TK700ST: 104.59 × 1.08 / 12 = 9.41 feet maximum. Optical gap about 4.9 inches.
ST cuts the room depth needed but leaves lamp maintenance the same
The ST sits about two feet closer at the nearest 120-inch position, but both are still lamp projectors. If the screen serves for television every evening, look at laser or LED alternatives on their own, and do not assume the short-throw upgrade gets rid of lamp replacement.
How we worked this out
BenQ TK700: Nearest 120-inch position 9.82 feet. Lamp light source. BenQ TK700ST: Nearest position 7.84 feet. Difference 1.98 feet. Lamp light source.
Don't let a brighter rating override a mount that fits
About 7 percent more is the TK700’s rated output. Neither manufacturer figure proves a 7 percent advantage in the picture mode you prefer. A shorter lens that keeps the projector out of a walkway or spares you a new ceiling mount is a firmer reason to choose the ST.
How we worked this out
BenQ TK700: Published 3,200 ANSI lumens. BenQ TK700ST: Published 3,000 ANSI lumens. 3200 / 3000 - 1 = 6.67 percent. No same-mode measurement supplied.

Spec by spec
Where they really differ
| Spec | BenQ TK700 | BenQ TK700ST | In practice |
|---|---|---|---|
| 120-inch optical distance | About 9.8 to 12.7 ft | About 7.8 to 9.4 ft | For this screen size, the optical intervals never overlap. |
| Lens adjustment | 1.127 to 1.46 throw, 1.3x zoom | 0.9 to 1.08 throw, 1.2x zoom | A mount you already have may work for one model and not the other. |
| 4K/60 input lag | 16.7 ms, published | 16.7 ms, published | Short throw helps with placement and does not make a console mode faster. |
| Light source | Lamp, 3,200 ANSI-lumen claim | Lamp, 3,000 ANSI-lumen claim | Lamp upkeep applies to both. The small gap in rated brightness is not a calibrated picture comparison. |
| Streaming setup | External source required | External source required | Do not mistake either exact package for a streamer-equipped STi bundle. |
Trade-offs
What each pick costs you
With BenQ TK700
- Streaming relies on a separate device that you have to connect.
With BenQ TK700ST
- The TK700STi streaming dongle is not part of this exact TK700ST package.
