The luminosity is measured in ANSI lumens. For the home projector, the luminosity has to be at least around 700 ANSI lumens.
The place where the projector is installed has a very important role in choosing the right video equipment. For the rooms with controlled artificial light and no natural light there is no need for a projector with a very white light, which is necessary in the rooms with many windows and a lot of natural light sources.
For the small rooms a 700 ANSI lumens are sufficient ,in the slightly light rooms are recommended 100 ANSI lumens and for the places with strong light the ideal projector is one with 2000 ANSI lumens.
In some cases, the luminosity calculated by the producers was created after the computer signal which is stronger than the video signal.
The two major factors that need to be considered when we are talking about the image quality are the image uniformity and the resolution. The resolution represents the number of pixels which create the image. The most common resolutions are SVGA and XGA. A projector with XGA resolution has an almost doubled pixels number than a SVGA but also costs a lot more.
For a better quality of the image there is need for something more than just resolution. The uniformity of resolution is also important. This represents the percentage between the luminosity from the center of the image and the one at the edges. A larger percentage results in image continuity. To achieve this, the percentage needs to be at minimum 85 %.
The connectivity and compatibility are factors which influence the contrast and the clarity of the image. The recommended projectors to become home cinemas usually have many entrances, special micro chips and other options. Other projectors without being created for the home cinema features are offering a high quality image.
