Google is said to be testing support for variable refresh rates (VRR) in the Chrome OS 101 Dev Channel, according to a report by About Chromebooks. The feature could improve gaming experience on Chromebooks.
About:
Refresh rate is the number of times a display is capable of refreshing in a second.
It is measured in hertz (Hz). So, a 30 Hz or a 60 Hz display can refresh 30 or 60 times per second, respectively. The higher the refresh rate, the better the quality of viewing experience.
Displays with over 120 Hz can deliver a smoother and more comfortable viewing experience. This is necessary while playing video games or watching videos.
VRR supports a wide range of refresh rates, allowing its refresh rate to change in real-time based on the frames-per-second (FPS) rate coming from a source device such as a gaming console.
VRR is also termed as dynamic refresh rate or adaptive refresh rate by different device makers.
VRR is designed to eliminate syncing issues that arise when the refresh rate of a display does not match with the FPS of the content from a source device. Issues such as screen-tearing, judder (wobbling effect) and lag are common when refresh rate and FPS are not synchronised.
