What Details Should I Pay Attention To When Buying A Micro Projector?

First of all is to see whether there is a screen function. This function works well for young people. Many video apps now support the screen projection function. When watching a movie, select the screen projection, and then select the pico WIFI projector to realize the large screen viewing. This means that as long as you have a mobile APP membership, you won't have to buy a video membership with a pico WIFI projector. This way can save a lot of costs, according to the observation of the general pico WIFI projector video membership annual fee in 299 yuan or so a year. So pay attention to this feature when you buy it: it's easy to use and it saves money. Autofocus also requires special attention, as the pico WIFI projector can be out of focus even if it is fixed in one place for half an hour. This means that the user needs to pause the image and constantly focus it, even if the pico WIFI projector is fixed. 

The autofocus function is to measure the distance between the projector and the projection screen according to the rangefinder, and then use the microprocessor to read the distance measured by the rangefinder. At this time, the stepper motor drives a zoom projection lens to rotate to this position to complete the autofocus. This process usually takes a few seconds, and the autofocus feature is mature and reliable through evaluation.
