A big image from twenty centimeters, 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.
Short throw without the compromise on resolution, and self-contained on top — the specification omits native contrast, and everything else is stated. Key figures: Short throw · 4K HDR · 3,000 ANSI lumens · Google TV built in. Amazon.com had an offer at $1,599 on October 25, 2026. Our score: 7.4/10, specification-checked.
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 theater 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.
Buying it in the United States
Amazon.com lists this model (ASIN B0FKD9YSJ5) and had an offer at $1,599 on October 25, 2026. The price box on this page is refreshed live and takes precedence over that figure.
In its favor, and against it
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

What gets asked most
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.
Our score
7.4/ 10
Short throw without the compromise on resolution, and self-contained on top — the specification omits native contrast, and everything else is stated.

What these short and ultra short throw projectors do not share
If price decides: Hisense Laser Cinema PT1 ultra short throw laser projector, at $1400.
Who should pick this one, among short and ultra short throw projectors
A room too small for a long throw projector where the picture still has to be 4K, and where one object is preferable to three.
Sources
Specifications: the manufacturer sheet and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
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 catalog 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 · Bose 2.1 audio · Google TV · 150-inch image · three HDMI with ALLM
The most expensive projector in this catalog, and the most complete: a 3LCD laser ultra short throw with Bose audio, Google TV and 4,000 lumens rated to ISO and IDMS standards.
Best for: A living room where this is the television — with the Hisense PT1, one of the two machines here sold and specified as a replacement for one.
Ultra short throw · 4K · laser · 2,500 lumens stated · 80–150 inch image · Dolby Vision and Atmos · HDR10+ · 240 Hz · screen not included
A laser television in the literal sense: an ultra short throw machine that sits under the screen, decodes Dolby Vision and Atmos, and is sold without the screen it needs.
Best for: A living room that cannot take a ceiling mount, where the projector has to look like furniture and work as a television.
