A big image from twenty centimetres, and a screen that must match · review
BenQ TK705STi 4K HDR short throw projector with Google TV review
The 4K version of the short-throw idea, with Google TV on board — a self-contained machine that sits close to the wall and needs nothing else plugged into it.
The bottom line Short throw without the compromise on resolution, and self-contained on top — the specification omits native contrast, and everything else is stated.
What the combination buys
A 4K image from a machine that sits close to the wall, with the streaming system already inside it. In a small living room, that is three problems solved at once: distance, cable run and source.
The brightness figure
3 000 ANSI lumens, stated. In a measured unit, so it can be compared with any other projector on this shelf that publishes one — and it cannot be compared at all with a machine quoting an unqualified figure, because there is no conversion between the two.
The part that will age
The operating system. Which services run, and at what resolution, is a licensing question rather than a hardware one, and it changes with firmware. Check the platforms you actually subscribe to on the maker’s own page before buying, because nothing on the box addresses it.
What is missing from the sheet
A native contrast ratio. On a projector aimed at home cinema that is a real omission, and this page reports it rather than repeating a dynamic figure in its place.
The screen, still
Short throw exaggerates surface imperfections. Not to the degree an ultra short throw machine does, and enough that a flat surface repays its cost here more than it does at the back of the room.

What we like, and what we don't
Strengths
4K and short throw together, which is a combination the shelf below this price does not offer
Google TV on board removes a box, a cable and a remote
3 000 ANSI lumens stated, comparable directly with any other machine publishing ANSI
Compromises
No native contrast figure published in the listing
The built-in system is the part that ages, and service licensing changes with firmware
Short throw still wants a flat surface — a plain roller screen will show its ripples

Questions people actually ask
Is short throw worse than long throw for image quality?
Not inherently. The lens works harder and the light arrives at a steeper angle, which makes the surface matter more, but the panel and the light source are the same class of components. What changes is what the screen has to be.
Do I need a special screen?
Not the specialist CLR surface an ultra short throw projector needs, and flatness matters more than it would at the back of the room. A fixed frame is the safe answer; a tab-tensioned roller is the compromise that works.
Short throw · Full HD 1 920 × 1 080 · 3 500 ANSI lumens · 10 000:1 stated contrast · 3D Ready · keystone
A short-throw 1080p projector at the accessible end of a family that is usually expensive — it sits close to the screen without needing the rigid, matched surface an ultra short throw machine demands.
Best for: A small room where a projector at the back is impossible, and where a rigid ALR screen is not in the budget.
Ultra short throw · 4K · 2 600 ISO lumens · 6 000:1 NATIVE contrast · Dolby Vision · 1 ms input lag · up to 200 inches
The only machine in this catalogue that publishes a native contrast ratio — 6 000:1 — alongside a measured brightness figure, which is what makes it comparable rather than merely impressive.
Best for: Someone who reads specifications and wants an ultra short throw machine whose figures can be checked against another that publishes the same ones.
Ultra short throw laser · 4K · 4 000 lumens stated · 3LCD · AI processing · Bose audio · Google TV · 150-inch image · 5-year warranty
The most expensive machine in this catalogue, and the most complete: a 3LCD laser ultra short throw with Bose audio, Google TV and a five-year warranty stated.
Best for: A living room where this is the television — the only machine here that is genuinely sold and specified as a replacement for one.
