Screen resolution
Resolution of built-in displays in glasses equipped with such equipment — that is, models for PC / consoles, as well as standalone devices (see "Intended use").
The higher the resolution, the more smooth and detailed the “picture” is given out by glasses, all other things being equal. Thanks to the development of technology nowadays, models with Full HD (1920x1080) screens and even higher resolutions are not uncommon. On the other hand, this parameter significantly affects the cost of points. In addition, it is worth remembering that in order to fully work with high-resolution displays, you need powerful graphics capable of playing relevant content. In the case of glasses for PCs and set-top boxes, this puts forward corresponding requirements for external devices, and in standalone models you have to use advanced integrated video adapters (which affects the cost even more).
Refresh rate
The refresh rate supported by the glasses' built-in screens, in simple terms, is the maximum frame rate that the screens are capable of delivering.
Recall that screens are provided in models for PC / consoles and in stand-alone devices (see "Intended use"). And the quality of the picture directly depends on this indicator: other things being equal, a
higher frame rate provides a smoother image, without jerks and with good detail in dynamic scenes. The flip side of these benefits is an increase in price.
It is also worth considering that in some cases the actual frame rate will not be limited by the capabilities of the glasses, but by the characteristics of the external device or the properties of the content being played. For example, a relatively weak PC graphics card may not be able to pull out a high frame rate signal, or a certain frame rate may be set in the game and not provide boosting. Therefore, you should not chase after large values and
points with a frequency of 90 fps will be enough.
