3 Tips Help You Get the Most Suitable Home Projector

You may be dazzled when choosing multiple types of projectors on the market and wondering which projector is right for you. Besides the brightness and the resolution, there are other three parameters that are also vital to choosing the suitable common projector for you when building a home theater.

1. Projection Focal Length

According to the different focal lengths of the projector, which is usually from 50mm to 210mm, the lens can be divided into a short-throw lens, standard lens, and telephoto lens (long-throw lens). The smaller the numerical value, the shorter the focal length, and vice versa.

If you want to project a large picture at a short distance, you need to choose a projector with a short-focus lens. Generally, the projectors use standard lenses, and the popular laser TVs usually use ultra-short-throw lenses.

2. Throw Ratio

The throw ratio refers to the ratio value of the projection distance to the width of the projected screen in the definition of the formula. The throw ratio of standard projectors is usually between 1.5 and 1.9. We usually call a projector with a throw ratio of less than 1 a short-throw projector, and a projector with a throw ratio of less than 0.6 as an ultra-short-throw projector.


3. Contrast Ratio

The brightness and the resolution are two parameters that people pay most attention to when purchasing a projector. However, the contrast ratio is also an essential parameter. The combination of contrast, brightness, and resolution makes the color of the home projector's image stand out, creating a unique large-screen image. 

The contrast ratio of the projector refers to the ratio of the luminance of the brightest area to that of the darkest area of the screen. The larger the ratio, the more gradient levels from the darkest to the brightest, and the richer the color expression, providing a clearer and more eye-catching image.

At present, the nominal contrast ratio of most LCD projector products is around 400:1 (ANSI), while the modern computer LCD monitors have a contrast ratio of between 1000:1 and 3000:1. For watching rich photos and video animations, it is recommended that you should choose a high-contrast projector with a ratio of 1000:1 or more. 

What Kind of Projector is Best for Home Use? 

If you want to get an extremely cost-effective home movie projector, JIRENO CUBE4 can be your initial choice. Although it is equipped with a standard fixed focus lens, it can also adjust the projected image size

Nowadays, the throw ratio of the projector is constantly getting smaller, so that the projector can project large-screen images within a short distance. Take it with a 16:9 aspect ratio as an example, to project a fixed 100-inch projection screen size, you only need to leave a space with a distance of 2.5 meters far away from the projection screen. The CUBE4 fashionable projector has the ability to project a maximum of 200-inch images, making it a highly affordable projector under $300.


For renters or people with irregular room structures, the CUBE4 cinematic projector can make it unnecessary to choose between image quality and screen size as you can get a superior image and a large screen simultaneously, eliminating the concerns of many projector enthusiasts users suffering from the small indoor space. 

With the LCD technology, the CUBE4 projector with full HD can achieve the unambiguous contrast ratio almost the same as an LCD computer monitor, far ahead of other projectors, allowing you to enjoy a vibrant, vivid image full of life and sharpness without loss of detail. Overall, the CUBE4 projector possesses excellent perceived contrast and is able to handle the image color well in ambient light.
