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.

In brief

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. Key figures: Full HD 1080p · 1,200 ANSI lumens · 4K signal accepted · 5G Wi-Fi · Bluetooth · up to 300-inch image. It is a European model with no Amazon.com offer on October 25, 2026. Our score: 7.8/10, specification-checked.

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 favor. “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-meter screen at three meters 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-meter image is dim. Two to two and a half meters 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.

Buying it in the United States

Not sold on Amazon.com when we checked on October 25, 2026. This is a model of the European catalog: we hold Amazon references for it in Europe only, so the button can only run a search on Amazon.com. Read it as a description of the design, and buy from the list below.

In its favor, and against it

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

What gets asked most

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-meter image is where this machine looks its best.

Our score

7.8/ 10

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.

Who should pick this one, among full HD projectors

A first projector in a room that can be darkened, for someone who wants a large image without a large budget.
