Brief conclusions of the comparison projectors

The Epson EpiqVision Mini EF-22 and EF-21 projectors have similar features such as 1920x1080 pixel resolution, HDR support, and 1000 ANSI lumens brightness. However, the EF-22 stands out with more advanced features like motorized focus and automatic keystone correction, making it more convenient to use. While the EF-21 has a simpler design and less impressive contrast, the EF-22 offers higher image and sound quality thanks to built-in speakers with Dolby Audio. Users note that the EF-22 is better suited for watching movies in dark rooms, whereas the EF-21 may be less effective in this regard due to its low contrast ratio. Overall, the EF-22 is a more versatile and powerful option, while the EF-21 may appeal to those looking for a more affordable projector for everyday use.

Glossary

Noise level (nominal)

The maximum noise level generated by the projector.

In most models, the main source of noise is the cooling system — it often uses fans to efficiently remove the heat generated by the lamp. Of course, the lower the noise level, the more convenient the projector is to use, the less inconvenience it causes, and the better the sound accompaniment of the “picture” is heard (if it is provided at all). On the other hand, as the size and power increase, the noise level also inevitably increases, and measures to reduce it significantly affect the cost of the projector.

Portable models are the quietest (see "Main purpose") — most of them do not have active cooling and practically do not make noise, except for control keys clicking and other similar sounds. Therefore, this indicator for such projectors may not be indicated at all. The most "loud" are professional projectors — in them the noise level can reach 50 dB (human speech level at medium volume).

Noise level (energy-saving / quiet)

The noise level in the ECO mode is significantly reduced, due to the reduction in heat generation. The active cooling system (fan) slows down, thereby significantly reducing noise. Usually, in economy mode, the noise threshold does not exceed 30-40 dB, depending on the model of the projector.
