Radeon™ FreeSync Technology | AMD
src: www.amd.com

FreeSync is the brand name for an adaptive synchronization technology for LCD displays that support a dynamic refresh rate aimed at reducing screen tearing. FreeSync was developed by AMD in collaboration with VESA and released in 2015 in response to Nvidia's proprietary, closed, and more expensive G-Sync. FreeSync is royalty-free, free to use, and has no performance penalty.

Adaptive-Sync

In 2015, VESA announced Adaptive-Sync as an ingredient component of the DisplayPort 1.2a specification; FreeSync is a hardware-software solution that uses DisplayPort Adaptive-Sync protocols to enable smooth, tearing-free and low-latency gameplay. FreeSync has a dynamic refresh rate range of 9-240 Hz. FreeSync has also been implemented over HDMI.

Advantages

  • Helps improve battery life by reducing the refresh rate of the panel when the screen is static (meaning, the previous frame was the same as the current one).
  • Ensures that the transition between refresh rate is seamless and undetectable to the user.
  • Can be enabled by plug and play, making it transparent to the operating system and end user.
  • Reduces implementation complexity of the Timing Controller (TCON) and panel by keeping the GPU's pixel clock rate constant and varying blank parameters.
  • Dynamically adapts the display refresh rate to fixed video content frame rate for a power efficient and stutter-free video playback with anything over 30FPS.
  • Dynamically adapts the display refresh rate to variable gaming content render for low latency and a smooth, virtually stutter-free gaming experience.

FreeSync 2

In January 2017, AMD announced the second generation of FreeSync. FreeSync 2 expands beyond the territory of its predecessor by also including standards for things like color and dynamic range. Requirements include removing the minimum frame rate, and setting a maximum on screen latency. FreeSync 2 also doubles the color and brightness spaces, and communicating the screen's specifications to the driver, enabling automatic support for high dynamic range.
