WiMiUS K1 Full HD projector, 1 200 ANSI lumens review
A 1080p projector that states 1 200 ANSI lumens — a measured unit at a price where the shelf usually does not — and that accepts a 4K signal without displaying one.
The bottom line An honest budget projector with a dishonest-sounding headline: the ANSI figure is real and useful, the "4K support" is signal acceptance, and the page says which is which.
The two numbers, separated
1 200 ANSI lumens is a measurement, and stating it at this price is unusual enough to count in the machine’s favour. “4K support” is signal acceptance: the projector takes a 4K input and shows it at its native 1 920 × 1 080. Both claims are true; only one of them is about the panel.
What that means in practice
You can leave a console or a player set to 4K and the picture will appear. What you will see is a good 1080p image, which on a two-metre screen at three metres is closer to a native 4K picture than the specification gap suggests.
The image size to aim for
Not 300 inches. Light per unit area is what you see, and a 1 200 ANSI machine spread across a seven-and-a-half-metre image is dim. Two to two and a half metres wide, in a room where the light can be controlled, is where this projector is at its best.
What the listing does not publish
A contrast ratio, and a throw ratio. The first is a real omission at any price. The second matters more practically: without it, the distance the machine needs has to be found in the manual before deciding whether it fits.
The connections that come free
Dual-band Wi-Fi and Bluetooth. The second is more useful than it looks on a projector, because it sends the sound to a speaker without a cable crossing the room — and the built-in speaker on any machine at this price is a fallback.

What we like, and what we don't
Strengths
States 1 200 ANSI lumens, which at this price puts it in a small minority
Dual-band Wi-Fi and Bluetooth, so a phone or a soundbar connects without a cable
Accepts a 4K signal, which means a source can be left at its native output
Compromises
"4K support" means the signal is accepted and shown at 1080p — the panel is Full HD, and the listing's wording invites the other reading
The stated 300-inch maximum is a maximum: at that size the image is at its dimmest
No contrast ratio is published in the listing

Questions people actually ask
Does "4K support" mean it is a 4K projector?
No. It means the machine accepts a 4K signal and displays it at its native 1080p. That is a genuinely useful feature — a source can be left at its native output — and it is not the same as a 4K panel. Three different machines are sold as 4K, and this is the third kind.
Can it really do a 300-inch image?
It can throw one, and it should not. The same light spread over a larger area is dimmer everywhere: at 300 inches, 1 200 ANSI lumens is thin. The maker states a maximum rather than a recommendation, and a two-to-two-and-a-half-metre image is where this machine looks its best.
Full HD 1 920 × 1 080 · 5 200 ANSI lumens · 10 000:1 stated contrast · 3D · keystone
The brightest machine in this catalogue by its stated figure — 5 200 ANSI lumens — which is what makes a 1080p projector work in a room you cannot darken.
Best for: A room with daylight, or a very large image, where light matters more than pixel count.
Native 1080p · Netflix and Dolby support stated · smart system built in
A compact 1080p projector sold on its built-in applications rather than on its optics — which makes the licensing question, not the brightness figure, the thing to check.
Best for: A second room or an occasional setup, where a self-contained machine matters more than a comparable specification.
Native 1080p · 4K signal accepted · Android 13 · electric focus · auto keystone · dual-band Wi-Fi · Bluetooth 5.2
The entry point of this catalogue: a 1080p machine with electric focus, automatic keystone and Android on board, whose brightness the maker does not state in a measured unit.
Best for: An occasional projector for a dark room, a garden wall in summer, or a first machine bought to find out whether projection suits the household.
