The laser answer to the X500i: the same 0.69 short throw and the same 4.2 ms gaming path, but with a 20,000-hour laser-phosphor engine pushing 3,200 ANSI lumens instead of 2,200. At 6.8 lb it is among the lightest projectors here bright enough to use with the lights on.

What it does well

3,200 ANSI lumens from a short-throw laser chassis that weighs under 7 lb
The 20,000-hour laser reaches full output in seconds and never needs a lamp
4.2 ms at 1080p/240 and 8.3 ms at 1080p/120
Puts a 100-inch image up from about six feet, so it fits a bedroom or apartment
31 dB is quiet for a laser projector this bright

What it gives up

No lens shift and only a 1.2x zoom, so placement is close to fixed
HDMI 2.0 caps 4K at 60 Hz
A single 5 W speaker — a soundbar is not optional
Optoma's UHZ35ST is brighter, lighter and throws shorter, though it has no zoom and no streaming

The two lists above are read off manufacturer specifications and published measurements, not from owner reports. Where owner discussion has been collected it appears separately below, so the two are never mistaken for each other.

Throw calculator

Worked from this projector’s published throw ratio of 0.69–0.83:1. Estimates: a real install loses a little to lens offset, and zoom ranges are quoted at the extremes of the lens.

The brightness figure is measured to a nine-point screen standard and is comparable with the rest of the catalog.

What owners say

This projector arrived into a specific gap and owners recognised it immediately: a genuinely short throw ratio with a laser light source, at a time when the short-throw category was all LED and comparatively dim. Owners shopping that category had been weighing two LED models against each other and describe this as the brighter third option they were hoping for.

The throw ratio matters more than the brightness for some owners. It matches BenQ's older short-throw lamp projectors, which means owners replacing one can put this in the same mount position — a detail that decides the purchase when the ceiling is plastered and the mount cannot move.

The complaint is price. Owners following the launch expected it to land near the LED competition and it did not, and several concluded the cheaper standard-throw sibling was the better buy for any room that could take the longer distance. Owners also note that short throw is a vague term and advise checking a throw calculator against a specific screen size and distance rather than shopping by category label.

What owners like

Owners with short rooms welcomed the 0.69 to 0.83 throw ratio specifically — it matches BenQ's older short-throw lamp models, so owners replacing one can reuse the existing mount position
It is brighter than the LED short-throws it competes with, and owners shopping that category name the extra light as the reason to consider it
The laser light source draws the usual credit over LED and lamp rivals for longevity and instant full brightness
Owners tracking the category describe it as the short-throw option they had been waiting for, since previous BenQ short-throws were not short enough for their rooms

Common complaints

It launched meaningfully above the LED short-throws it competes with, and owners watching the category describe the pricing as higher than expected
The standard-throw sibling costs less and owners say it looks like the better buy for anyone whose room can take a longer throw
Owners with a fixed mount close to the screen found even this throw ratio too long for their distance
A single 5 W mono speaker, which owners treat as a placeholder

Questions owners ask about the BenQ TK710STi

How short is the throw, in practice?

0.69 to 0.83, which puts a 100-inch image up from roughly six feet. Owners note it matches BenQ's older short-throw lamp models, so a mount positioned for one of those will work for this.

How does it compare with the LED short-throws at a similar price?

It is brighter — 3,200 ANSI lumens against roughly 2,200 for the LED alternatives — and it costs more. Owners in rooms they can darken generally found the LED models bright enough; owners with any ambient light picked this one.

Should I buy this or the standard-throw version?

Owners are consistent: if the room can take the longer throw, the standard-throw sibling costs less and is the better buy. The short-throw premium only makes sense when the distance genuinely is not available.

Is 'short throw' a useful category to shop by?

Experienced owners say no, and put it bluntly — short throw is as vague as hot or cold. The useful approach is to take your actual screen size and your actual lens-to-screen distance and check them against a throw calculator for each specific model.

Is the built-in audio usable?

It is a single 5 W mono driver and owners treat it as a placeholder. Budget for a soundbar or a receiver.
