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 initially developed by AMD in response to NVidia's G-Sync. FreeSync is royalty-free, free to use, and has no performance penalty. As of 2015, VESA has adopted FreeSync as an optional component of the DisplayPort 1.2a specification. FreeSync has a dynamic refresh rate range of 9–240 Hz.〔 As of August 2015, Intel also plan to support VESA's adaptive-sync with the next generation of GPU.〔http://www.forbes.com/sites/jasonevangelho/2015/08/21/intel-throws-its-support-behind-amd-freesync-style-display-technology/〕 ==Advantages== * Presents no 2% performance penalty, unlike G-Sync〔 * 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).〔(【引用サイトリンク】url=http://www.amd.com/Documents/FreeSync-Whitepaper.pdf )〕 * 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「FreeSync」の詳細全文を読む スポンサード リンク
