Sometimes we need something bigger to watch our favorite movies, something that can get close to the feeling of being at the cinema enjoying a movie. In recent times, more and more models of video projectors have appeared on the market that can meet this need, making it possible to transform our living room into a splendid movie theater. But with all these models it is really difficult to get your bearings so we decided to choose ten video projector models for you, from the cheapest to the most expensive, all with a very high quality ratio. It is important to remember that in order to choose a video projector it is necessary to evaluate the lamp life, the degree of brightness (lumen) and the connectivity of the device.
The first and fundamental evaluation to do, before buying a projector, concerns the use that it intends to do. Depending on the use you want to make of the projector, you will have to evaluate some technical features, which can make it suitable, for example, to rooms that are completely dark or partially illuminated, and suitable for watching movies or more suitable for general use, such as the projection of a Power-Point presentation, or playing video games, watching photos or more. The characteristics that influence the intended use, and that you will have to take into consideration, are the brightness of the lamp, the contrast of the image, the resolution and finally the screen size.
Brightness The brightness of the light beam emitted by a projector lamp is measured in lumens (lm), and determines how visible the projected image will be in the presence of ambient light: the lower the brightness, the dimer the image in even partially lighted. On the other hand, a projector with less brightness needs a less illuminated environment for the image to be clearly visible, but the definition level is better. We can identify three brightness bands as a reference for choosing the projector:
1500-2500 lm: home theater projectors require a completely dark environment
2500-4000 lm: general purpose floodlights require a partially darkened environment
4000 lm and beyond: office projectors, they render well even in illuminated environments
We will also see how brightness affects the size of the projected image.
Contrast As we have mentioned, a higher brightness normally results in a poorer image performance: in particular, a very bright projector causes losses in contrast. There will therefore be a lower sense of depth of the images and of the color range, in particular as regards the films. The more the lamp emits light, in fact, the more technically difficult it is to preserve dark areas in the image. For these reasons, home theater projectors have low brightness and need a completely dark environment for optimal performance, while projectors for more general or office use are much brighter, so as to project visible images even in semi-bright environments. Also with regard to the contrast, we can indicate the values that are relevant for the purposes of use:
600000: 1: high-end home theater projectors
50000: 1: versatile projectors for home theater and general use
10-25000: 1: general purpose projectors
It must be remembered that the headlamps, with the exception of those that use LED technology, have a maximum lifespan, and that the brightness of the lamp gradually decreases with use, until the moment of replacement occurs. The longevity of a lamp is expressed in hours of use, and can range from approximately 3,000 to 10,000, and also varies depending on the mode used.
Resolution in this field the projectors do not reserve many surprises, the resolutions available are in fact the same as those for computer monitors. The more advanced models, from the prices that we consider today inaccessible, can also touch the Ultra HD resolution (3840 × 2160 p), but it will still take a few years before it becomes a market standard. Among the commercial-type devices, instead, there are projectors that support Full HD resolution (1920 x 1080p), in particular those aimed at home theater, or HD (1280 x 720p), in particular among projectors for more general use. . If what you are looking for is a projector to watch movies and series, the Full HD resolution will be a good feature to have, while if you are looking for an office projector or for educational use you can safely put it off and stay on lower resolutions.
Screen size Expressed in inches, the size measures the diagonal length of the projected light rectangle. This factor is relevant whether you need to buy a projection screen or want to project images onto a white wall. The maximum screen size, it must be said, also affects the brightness of the lamp: the less luminous the lamp, the smaller the screen. In principle, the minimum dimensions of the projected rectangle are around 30-40 “without large variations between more or less luminous models, but it is on the ideal size of the screen that the gap manifests itself: the projectors with weaker lamps stop in fact around 150 “of ideal diagonal, while the brighter models can reach up to double the size (300”) and beyond.Expressed in inches, the size measures the diagonal length of the projected light rectangle.

All these factors must be decisive in our choice. And now the list of the 10 best video projectors!
