Projectors are currently manufactured in several different technologies. This is how we distinguish DLP projectors (Digital Light Processing), LCD projectors (Liquid Crystal Display), LCOS projectors (Liquid Crystal on Silicon), etc. Depending on the light source, they are divided into projectors with standard lamps (UHP, Metal Halide) and LED lamps.
Depending on the purpose, you can choose a professional projector, a short or ultra-short throw projector, an interactive projector, a pocket projector, a home theater projector or a multi-purpose projector. When choosing a suitable model, it is necessary to pay particular attention to the light intensity (illumination), resolution and image format.
Resolution is the number of pixels that produce an image. The higher the resolution or the higher the pixel density, the higher the quality and sharper the image. It is important, however, that the desired resolution is also supported by the source.
For easier understanding, we attach the resolution scale:
