3D monitors

3D

— the ability of the monitor to work with "volumetric" 3D content. The principle of operation of such screens is based on the fact that each eye receives its own image, slightly different from what the other eye sees (as when viewing real objects). This creates the illusion of three-dimensional image. Specifically, the screen works in this way: the monitor alternates “left” and “right” frames, and the user looks at the screen through special glasses, thanks to which each eye sees only its own part of the image. In effect, half of the video stream is output to each eye; accordingly, so that the quality of the “picture” does not deteriorate, the overall frame rate should be at least twice as high as usual. Therefore, this indicator in 3D monitors is at least 120 Hz (60 Hz for each eye). However, not every screen with refresh rate of 120 Hz and above is 3D model.

Also note that before purchasing such monitor, you need to take into account number of nuances. Firstly, to work with 3D, you will need fairly powerful graphics card, especially when it comes to modern games. So before buying, it's ok to clarify whether the system will “pull out” the planned 3D content. Secondly, the mentioned 3D glasses may not be included in the package (there are screens that do not require glasses, but they are extremely rare). Thirdly, the 3D picture must be seen with both eyes at once; with binocular vision disorders (strabismus, missing one eye, etc.), normal viewing of such content will not be possible.
