Projector Buying Guide

With the great immersive viewing experience brought by the large screen, more and more families will choose to buy projectors. Today we'll explore a few key points on how to choose the home projector of your choice.

Contrast

Contrast is the contrast between the darkest and whitest areas in an image and is the most important indicator of image quality in a projection system. It describes the comparison between the brightest and the darkest light output on the screen. Generally speaking, the larger the picture contrast, the clearer and more eye-catching the picture, and the richer and more delicate the color of the projected picture. The lower the contrast, the darker and less transparent the image appears as if covered by a layer of fog. And high contrast has a great impact on the sharpness, detail performance, and gray level of the projected image.

That's not to say, however, that the greater the contrast, the better the projector. For home use, the contrast ratio of 5000:1 is enough, if conditions permit, you can also choose from 10000:1 or above. In the process of using the projector, you can manually adjust the color parameters such as saturation and contrast of the picture.

Brightness

If you want a good viewing effect during the day and night, you must pay attention to the brightness parameters. The brightness can be seperate as light source brightness and ANSI lumens. The brightness of a light source is the brightness that is not decayed by lenses or other factors. The brightness value is very high, but it is completely invisible to the human eye, and the actual reference value is of little significance. ANSI lumens is the brightness after layers of attenuation, which simulates the brightness observed by the human eye, so ANSI lumens is a more realistic and reliable indicator of brightness.

The brighter the environment in which the projector is used, the more lumens it needs to make the picture clear. In general, projectors should have at least 2000 ANSI lumens without environmental constraints. Excessive brightness (over 4000 ANSI lumens) can cause eye discomfort and even sting. Therefore, home projector lumens are generally 1500-3000 ANSI lumens.

Resolution

Resolution is an important factor reflecting the clarity of the picture because some companies divide the resolution into standard resolution and compatible resolution, and it is difficult for consumers to distinguish without professional knowledge.

Let me talk about compatible resolutions first. For example, the standard resolution of a projector is 480p, but the compatible resolution is 1080p. Specifically, it is to compress 1080P film to 480P playback, it will not show format incompatibility. The actual image quality is still 480P. True and false resolutions depend on the chip. True 1080P requires a 0.47DMD chip and can project 1920x1080 pixels.

Gradient correction, wireless connection, and smart remote control

Smarter and more automated is one of the main lines of intelligent projection development. Entering 2022, sensorless focusing and automatic correction have become new trends in smart projection, and wireless connectivity and smart remote control functions are also very popular. Industry insiders pointed out that the more mainstream products will be clear at a glance when the product is turned on, and the sensorless focusing will remove the focus image that interferes with the line of sight, an
