Together with the resolution in pixels, you also have to look at the resolution, which will tell us if the projector is optimized to display content in panoramic (16: 9) or normal (4: 3) format. However, we can easily alternate between them digitally.
ResolutionĪs with the purchase of a television, one of the tips to buy a projector that cannot be missed is to look at the resolution that they are capable of supporting. Full HD 1.080p is essential for those looking for quality, while a resolution of 720p may suffice if what we want is to acquire a more affordable model. In this case, we recommend starting at a minimum of 1,500: 1, it is preferable to reach 2,000: 1 to obtain a viewing without any hits. In this regard, we must pay attention to the characteristics that manufacturers provide, since the real contrast is not the same as the dynamic on-off contrast (which is artificially increased and many prefer to advertise before the real one). In addition to attending to the brightness offered by a projector, we will also take into account the contrast ratio. The higher it is, the purity of blacks and whites will be more appropriate. In fact, if we have many lumens but the contrast is low, it is normal that the image quality suffers, resulting somewhat discolored because the impact of light on the screen affects the intensity of black. If you start from a minimum of 1,500 lumens, the experience of viewing in your home will be satisfied even with a light on, while if you usually watch movies in the dark, just under 1,000 lumens will be enough. This is the value, which is used by ANSI – standing for the “American National Institute of Standards.” When it comes to the factor of light output, it is important to take into consideration brightness lumens, which are typically expressed in ANSI lumens.
