How to choose

There are a lot of characteristics of image creation devices, but among them, there are the main ones:

  • Goals and objectives. The apparatus must fully cover the needs of the user.
  • Screen size. Most likely, the user knows the dimensions of the future screen. Using the measured data, it is possible to determine the required power of the device when operated in a room with artificial light. The formula is: X = 500xS, where X is the power and S is the area of the future screen.
  • Resolution. To play high-quality Blu-Ray or FullHD content, you need the right resolution for your projector. Optimal is 1920x1080 pixels. If the resolution is lower, the picture quality will fall.
  • Battery life. The battery capacity of each model is different and with it the duration of the device without recharging changes. The greater the battery capacity, the longer the portable projector can work.

When it is reasonable to buy mini projectors:

  • When there is an infrequent need to use a large device. If the desire to see a picture on the wall occurs infrequently, it is better to take a mini-model. Traditional projectors require a special mount and equipment, which will interfere in the inactive state.
  • For presentations in different locations. You can find a flat wall in almost any location, and you can take a cloth to nature and stretch it out.
  • In the case of frequent travel. It will not be difficult to create a picture in the train on the wall of the compartment or on the top shelf.
