How to Choose Projector

If you don't know how to choose the projector, we advise you to follow below important parameters:
1、Resolution
The higher the resolution, the better the quality of the projected image.Most of the LED projectors in the market have 1080P high definition resolutions which we always called 1080P projector. There are also some flagship products that support 4K resolution, but the price is high, and they are generally used in professional home theaters.

2、 Brightness
The brightness of the projector is related to its own needs.Higher projector brightness, it can see the image clearly in very bright environment intensity during the day, while the projection effect in the daytime with low brightness is more general! We suggested buying a higher brightness within your budget.The brightness range is 3000 lumens to 4000 lumens. The advantage of high brightness is that it can avoid the embarrassing situation of turning on and off the lights while taking notes, which is especially important for people with office needs. In general, most 1080P projector can meet the needs of daily life.

3、Lens
At present, projector lenses on the market are mainly divided into two categories, namely all-glass lenses and high-transmittance coated resin lenses. Between the two, I recommend choosing an all-glass lens, because when the projector is used, the light source will generate high temperature. In this case, the resin lens will cause the image to be out of focus due to heat, and the image projection will be unstable.

The light transmittance and heat resistance of the all-glass lens is relatively stable, its refractive index is high, and the color reproduction of the projected image is relatively accurate. The problem that the screen is out of focus.
