The throw ratio of the Hisense C1 projector is 1.2:1.

This means for every 1.2 feet of distance from the screen, you'll get 1 foot of image width.

This ratio gives you some flexibility in where you place the projector, but you'll still need to plan a bit to get the best picture quality.

So, the Hisense C1 4K UHD Triple Color RGB Laser Portable Mini Projector can project images up to 300 inches and has some cool features like TriChroma laser tech.

According to the manufacturer, it covers 110% of the BT.2020 color gamut and supports Dolby Vision and HDR10, so the colors should look pretty vibrant and the picture quality is enhanced for both dark and bright scenes.

Sounds like a solid choice if you're after a cinema-like experience at home. According to our research, folks are generally happy with its brightness and clarity—you can even use it in semi-lit rooms, although it's best in the dark.

It also has Auto Keystone Correction and autofocus, making setup easier, which people seem to appreciate.

Now, about your question—unfortunately, the Hisense C1 doesn't have optical zoom or lens shift. This means you'll have to be careful about where you place the projector to get the best image. Ideally, it should be mounted at ceiling level or at the bottom of the projection area.

This lack of flexibility can be a bit annoying because you'll need to manually adjust it to get the right image size and focus. Also, our research suggests that while the built-in sound system is okay, it’s not as good as a dedicated audio setup, especially during louder scenes.

So you might want to think about adding an external sound system if the audio is important to you. Overall, if you can live with the placement limitations and don't mind spending a bit of time setting it up, the Hisense C1 could be a good addition to your home entertainment lineup.

It comes with smart TV functionalities and supports major streaming services like Netflix, which is a nice bonus.

The Hisense C1 projector has a contrast ratio of 1,000,000:1. This means it can show deep blacks and bright whites, which is pretty great for watching movies or playing games where you want those details to pop.

According to our research, this high contrast ratio helps a lot to clearly see dark and light areas in scenes.
