What is important in choosing a projector? This may confuse a lot of people before the purchase. The purchase of projectors focuses on the following six aspects, which are optical parameters, system parameters, configuration parameters, projection performance, connection interfaces and product specifications.

1. Optical parameters​


Optical parameters are mainly brightness parameters, resolution parameters, projection ratio and display ratio, etc. Brightness and resolution need to be higher the better, the higher the brightness and resolution, the better the picture quality.

2. System Parameters​


The system is mainly divided into the intelligent system and non-intelligent system, intelligent system is based on Android deep customization, generally speaking, the Android system higher will be more stable.

3. Configuration parameters​


Configuration mainly depends on the processor and memory, smart projector processors nowadays mainly use MTK and Amlogic, but also are ARM processors, preferably quad-core A73 architecture.

4. Projection performance​


Projection performance is primarily a function supported by the projector, such as support for autofocus, keystone correction or auto keystone correction.

5. Connection interfaces​


The current projector basically needs to meet the four types of interfaces HDMI, USB, SPDIF, and 3.5mm audio, if it is a portable projector, you can sacrifice the audio output interface.

6. Product specifications​


Product specifications are less restrictive, which is mainly in terms of size, power consumption, noise, net weight, etc. Noise and power consumption can choose lower, if there is a special use of demand, you can consider the size and weight, such as the need for portable use.
