I simply tried the projector and talked about the points that need to be paid attention to when purchasing a projector.
Brightness , which is definitely the number one consideration. A bright light covers a hundred ugliness, no bright light is nothing. To be specific, preferably 1000+ ANSI lumens. If it is mainly to turn off the lights at night, it is acceptable to be lower. Otherwise, as long as there is a little natural light, the picture is almost impossible to see.
Throw ratio is how far away the screen can be projected. In fact, this is related to brightness. Imagine a flashlight, the closer you get, the smaller and brighter the aperture, and vice versa. From this point of view, the projection ratio does not need to be too large, so that the light can be concentrated and the brightness can be relatively improved. In other words, if you can accept that the screen is smaller and the projector is closer to the screen, it can also increase the brightness.
The resolution , the cheap ones are basically physical 720 shakes into 1080, which is basically enough.
Audio , the sound is second only to the feeling of the picture, but if the built-in audio is too bad, you can actually plug in the audio. For example, using AirPods to listen to the sound through Bluetooth, the experience is actually good in the dead of night. However, those who are sensitive to delays should pay attention.
5G WiFi . If the network speed is not good, it will freeze, which will affect the experience. If WiFi 6 is supported, it is naturally better. Of course, if you use wired, you can ignore WiFi.
CPU/Memory , in view of the general rule of Android getting stuck, the stronger the hardware, the better. Specifically, it is best to have 2G+ memory.
Autofocus/Keystone . If it is hoisting, that is, it will not move after it is installed, these two are not so important. But if you often move in different rooms, it is a must-have function that affects the experience.
Noise , generally speaking, noise is acceptable.
Fever , if it is hoisted, it does not have much effect, unless it is forced to shut down due to overheating.
Having said that, how do you choose? In fact, the competition is already sufficient, and there are few hidden pits; looking directly at the price, choosing the most expensive one within the acceptable range is the simplest and most rude way.
