The refresh rate is the number of times per second that a display’s image is updated. It is measured in Hertz (Hz). A higher refresh rate means that the image on the screen will be refreshed more frequently, resulting in a smoother visual experience. Most modern displays have a refresh rate of 60Hz, but some high-performance monitors can have a refresh rate of up to 240Hz.
Refresh rate in VR
In virtual reality (VR), the refresh rate is an important factor that affects the overall user experience. A higher refresh rate can make the VR experience feel more realistic and immersive.
When a VR headset is used, the refresh rate refers to the number of times per second that the headset’s display updates the image for each eye. A high refresh rate can help reduce the motion sickness and disorientation that some users may experience.
Most VR headsets currently on the market have a refresh rate of 90Hz or higher. Some high-end VR headsets, like the Oculus Quest 2 and the Valve Index, have a refresh rate of up to 120Hz.
It’s also important to note that high refresh rate is not the only important factor, low latency and high resolution also play important role in VR experience.
