Refresh Rate Optimizer – standard monitor functionality and works as follows.
Monitors with high screen refresh rates are produced, top models for gamers support a frame rate of 144 per second). But to maintain this frequency there must be a powerful video card. But what if the video is fed to the monitor at a rate of 30 frames per second.
The monitor determines the frame rate in the input signal and automatically adjusts to display the image on the screen at the appropriate frequency. The monitor can display video at a rate of 25 frames per second, as well as many additional video standards.
This possibility is supported by monitors for about 15 years, but some manufacturers periodically, somehow or other, the standard function is called a new beautiful term and advertised as an extended functionality of the device.
