Shopping tips:

1 to learn how to use the projector.

Users should be familiar with the use of projectors before choosing to buy. Projectors are divided into three types when used: desktop orthographic projection, ceiling orthographic projection, desktop rear projection, ceiling rear projection and rear projection integrated box. Therefore, according to the use environment, determining the purchase type of the machine is the first step.

2. The brightness and contrast should be moderate.

Brightness is an important index to measure the performance of projector. Brightness is the intensity of light output by the projector to the screen. High brightness can make the projected image clear and bright. The high-brightness projector is dazzling when used in a small environment, which will make your eyes tired. Therefore, according to the specific area of the living room, the selected home projector brightness is generally between 500- 1000 lumens.

3. Choose a projector with appropriate resolution.

Projectors, like digital cameras and digital video cameras, are judged by resolution. It should be noted that the higher the resolution, the more expensive it is. There is also a compatible resolution, which is a step higher than its physical resolution. Like DC and DV, the higher the resolution, the clearer the projector image and the higher the price.

4. Pay attention to the projection distance

For home users, the living area is very limited, and the distance between the installed projector and the screen is not too big. Therefore, for the home environment with narrow space, the projection distance becomes one of the important conditions for choosing a projector. What users want to compare is the projection distance of different projectors with the same diagonal projection size, not the "shortest projection distance" on the specification table.

Verb (abbreviation of verb) consumables and after-sales service

For the projector, the light bulb is its only consumable, and its life is directly related to the use cost of the projector, so be sure to ask about the life and replacement of the light bulb when buying. At the same time, after purchase, you should sign an after-sales service contract or obtain a warranty certificate in time to avoid the worries of using the projector.
