Brightness

     Brightness is the light emitted by the projector. The higher the brightness, the clearer the projected picture.

Common units of brightness are ANSI lumen and lumen. ANSI lumen refers to the brightness of the projector screen, and lumen refers to the brightness of the projector light source. It is generally accepted internationally that ANSI lumens are used to represent brightness, so ANSI lumens should be used as a reference item when buying a projector. 1000ANSI lumens are about 3500 lumens.

Contrast

    Contrast is the ratio between the black and white of the projector screen. The higher the contrast, the richer and more natural the color of the screen, and the clearer the image. If the contrast is low, the screen will be white.

Resolution

    The resolution is the clarity of the projector screen, the higher the resolution, the clearer the screen. The resolution of a home projector must be at least 720p, and most projectors will be 1080p.

   The resolution is divided into standard resolution and compatible resolution. The standard resolution refers to the maximum definition that can present the picture; the compatible resolution refers to the resolution that the projector can play pictures or videos, regardless of the picture resolution.

Display chip

    The display chip is the chip that provides the image display function of the projector. The larger the size of the display chip, the higher the resolution of the picture.

    The size of the display chip is: 0.23DMD (native 480P resolution), 0.33DMD (native 720P resolution), 0.47DMD (native 1080P resolution), some projectors on the market use 0.33DMD display chip but the resolution is 1080p , which is achieved by using the TPR display chip dithering scheme.

Throw ratio 

   The throw ratio is the ratio between the projection distance and the size of the projected screen. The smaller the throw ratio, the shorter the distance to project a large-size screen, and the more space-saving it will be.

Zoom

   Zooming is the function of changing the size of the projector screen, and the size of the screen can be adjusted by changing the position of the internal lens of the projector.

Processor

    The processor includes CPU and GPU. The CPU is also called the central processing unit, which is responsible for processing the data information of the projector; the GPU, also called the image processor, is responsible for processing the image information in the projector as the name implies. The stronger the performance of the CPU and GPU, the stronger the smoothness, running speed, decoding ability, etc. of the projector.

Body memory

   Body memory includes running memory and storage capacity. The running memory is the capacity required by the projector when it is running. The larger the capacity, the less likely the projector will freeze. The storage capacity refers to the space that the projector can use to store files. The larger the storage capacity, the more files the projector can save .

Interface

    The interface is the connection port for the projector to connect to other devices. The common interfaces of projectors are: USB interface: input and output interface, which can connect various devices and decode files in various formats. HDMI interface: It is a fully digital video and sound transmission interface that can send uncompressed audio and video signals.

3.5mm audio interface: It is the interface for input and output audio.

Function

Automatic Keystone Correction: It can automatically adjust the squareness of the screen.

Auto Focus: Automatically adjusts the sharpness of the picture.

Far-field voice: AI voice assistant that directly evokes the projector without a remote control.

The functions of different projector models are also different. The more additional functions, the more convenient the projector is to use.
