What Are the Important Things to keep in Mind when Choose a Projector?

The projector, or say video projector, unlike other electronic goods, has the advantage that even purchased used it does not appear to be an obsolete asset such as a smartphone or PC that if purchased new, surely offers greater performance than a previously released model. The projector does not have a ram or internal memory or processor such as a PC, so the technical specifications of a projector released on the market months or years ago will have equal performance compared to a new model. It’s always been the same technology for years now. The thing matter only is the technical characteristics of the model and the conditions of use in which the projector is located at the time of Projector on rent in Noida. However, there are many other upgrades have been done in the projectors such as now you can get the video quality of even 4K resolution.

From a technical point of view, the visual performance of a projector depends on the combination of three main parameters: ANSI lumens, native resolution, contrast. The projector does not have a ram or internal memory or processor such as a PC, so the technical specifications of a projector released on the market months or years ago will have equal performance compared to a new model. To this we must consider the variable of the environment in which we project, or if there is natural or artificial light at the time of projection or if it is possible to completely or partially obscure the environment, as well as how far we are from the wall or curtain. The luminous flux according to the ANSI standard parameter. We are led to think that the higher the ANSI lumens, the higher the image quality.

ANSI Lumens

Often considered as the main parameter for assessing the value of a projector, with ANSI lumens the intensity of light emitted by a fixture is expressed, that is, the luminous flux according to the ANSI standard parameter. We are led to think that the higher the ANSI lumens, the higher the image quality, but choosing a projector-based only on the ANSI lumens can be misleading, as there are other technical parameters to evaluate as we will see later. Furthermore, buying a projector with a high value of ANSI lumens for a small room like a living room at home can be excessive, just think that to illuminate a screen of 80-120 inches, 800-1000 ANSI lumens of a branded projector is sufficient.

Don’t Get Confused with Resolution and Image Format

The resolution expresses the number of horizontal and vertical lines that make up the image, as well as the total number of pixels, i.e. the basic unit of the image, which the projector can reproduce and project on the screen. For example, with a projector with a native XGA resolution (1024×768), we will have the base of the image consisting of 1024 lines and a height of 768 for a total of 786.432 pixels. The maximum resolution, on the other hand, indicates a potential possibility of the projector to support a maximum resolution as it is electronically encoded. This means that a projector with a maximum resolution of 1920×1080 Full HD may work for 1080p reproductions.

Image Format instead indicates the proportion of the screen, for example, a 4: 3 means that the ratio between the base and the height is 4 units out of 3. A 16:9 or 16:10 ratio will indicate a more rectangular image. Generally, a projector allows you to change the image format for example from 4: 3 to 16: 9, in case you prefer a home cinema aspect. The difference between the chosen format and the initial image format will be filled by the typical black bands, horizontally or vertically.
