The original FreeSync is based over DisplayPort 1.2a, using an optional feature that VESA terms Adaptive-Sync. [ 9 ] [ 10 ] This feature was in turn ported by AMD from a Panel-Self-Refresh (PSR) feature from Embedded DisplayPort 1.0, [ 11 ] which allows panels to control its own refreshing intended for power-saving on laptops.

On displays with a fixed refresh rate, a frame can only be shown on the screen at specific intervals, evenly spaced apart. If a new frame is not ready when that interval arrives, then the old frame is held on screen until the next interval (stutter) or a mixture of the old frame and the completed part of the new frame is shown ().
front porch – blank while still moving right, past the end of the scanline, sync pulse – blank while rapidly moving left; in terms of amplitude, "blacker than black". back porch – blank while moving right again, before the start of the next scanline. Colorburst occurs during the back porch, and unblanking happens at the end of the back porch.
Screen tearing [1] is a visual artifact in video display where a display device shows information from multiple frames in a single screen draw. [ 2 ] The artifact occurs when the video feed to the device is not synchronized with the display's refresh rate.
Coordinated Video Timings (CVT; VESA-2013-3 v1.2 [1]) is a standard by VESA which defines the timings of the component video signal.Initially intended for use by computer monitors and video cards, the standard made its way into consumer televisions.
A vertical blank interrupt (or VBI) is a hardware feature found in some legacy computer systems that generate a video signal. Cathode-ray tube based video display circuits generate vertical blanking and vertical sync pulses when the display picture has completed and the raster is being returned to the start of the display.
