What is refresh rate ?

 Refresh Rates

As illustrated above, a higher refresh rate refers to the frequency that a display updates the onscreen image. The time between these updates is measured in milliseconds (ms), while the refresh rate of the display is measured in hertz (Hz).

The refresh rate of your display refers to how many times per second the display is able to draw a new image. This is measured in Hertz (Hz). For example, if your display has a refresh rate of 144Hz, it is refreshing the image 144 times per second. When paired with the high frame rates produced by a GPU and CPU working together, this can result in a smoother experience and potentially higher FPS.

In order to take advantage of higher refresh rates, three of the most important components to consider are:

• A monitor with the ability to refresh quickly.
• A CPU that’s fast enough to provide critical game instructions, including AI, physics, game logic, and rendering data.
• A GPU that’s fast enough to execute these instructions quickly and create the graphics you see on the screen.

The monitor can only display an image at the rate the system produces it, so it’s important that your CPU and GPU are capable of completing this process quickly. If your CPU and GPU are incapable of supplying the monitor with a sufficiently high number of frames then your monitor won’t be able to produce a high-refresh rate image regardless of how good its specs are.

If your monitor has a refresh rate of 144Hz but the GPU is only supplying 30 frames per second, that higher refresh rate is not being utilized.
