What are Variable Refresh Rates?
Definition and Purpose
Variable refresh rates (VRR) are a feature that allows a display to dynamically adjust its refresh rate based on the content being displayed. This is in contrast to traditional fixed refresh rate displays, which have a set refresh rate regardless of the content being displayed.
The purpose of VRR is to improve the visual quality of the display by reducing the likelihood of visual artifacts such as tearing and stuttering. Tearing occurs when the frame rate of the content being displayed is not an exact multiple of the refresh rate of the display, resulting in a partial or “tear” in the image. Stuttering occurs when the frame rate of the content is lower than the refresh rate of the display, resulting in a choppy or “stuttering” image.
By adjusting the refresh rate to match the content being displayed, VRR can help to eliminate or reduce these visual artifacts, resulting in a smoother and more natural visual experience.
How it Works
Variable refresh rates are a technology that allows a display to adjust its refresh rate dynamically based on the content being displayed. This is achieved by the display and graphics card communicating with each other to determine the optimal refresh rate for the current scene.
There are several benefits to using variable refresh rates. Firstly, it reduces screen tearing and stuttering, which can improve the overall gaming experience. Secondly, it can also reduce power consumption, as the display doesn’t need to refresh as frequently when the scene is static.
Variable refresh rates are typically implemented using either Adaptive-Sync or Free-Sync technology. Adaptive-Sync is a technology developed by AMD, while Free-Sync is developed by NVIDIA. Both technologies work in a similar way, by allowing the graphics card to communicate the current frame rate to the display, which then adjusts its refresh rate accordingly.
In order to use variable refresh rates, the display and graphics card must be compatible with the chosen technology. Additionally, the graphics card must be set to use the appropriate mode in its settings. This can typically be found in the “Display” or “Advanced” section of the graphics card’s settings menu.
