VRR (Variable Refresh Rate)

In News

• Google is said to be testing support for variable refresh rates (VRR) in the Chrome OS.

What is VRR?

• 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.

Significance of this technology

• Efficient streaming: This screen technology enables a monitor or a TV to communicate with a gaming console or a media streaming device much more effectively.
• It can improve gaming experience in both console and PC-based gaming.
  • Besides, the screen technology can give players an important edge, especially in competitive multiplayer games where split-second decisions are crucial for victory.
• In mobile devices: it saves battery power on them as the adaptive refresh rate does not run at the highest rate all the time and switches to a lower refresh rate during less graphic-intensive tasks.
