5679 * When a userspace application wants to play a video, the content follows a

5684 * - TV/NTSC (23.976 FPS)
5687 * - TV/NTSC (29.97 FPS)
5688 * - TV/NTSC (30 FPS)
5689 * - Cinema HFR (48 FPS)
5691 * - Commonly used (60 FPS)
5692 * - Multiples of 24 (48,72,96 FPS)
5694 * The list of standards video format is not huge and can be added to the

5696 * FreeSync to extends the front porch in order to attain the target refresh
5697 * rate. Such a switch will happen seamlessly, without screen blanking or

5699 * modesetting change compatible with FreeSync modes that only differ in the
5700 * refresh rate, DC will skip the full update and avoid blink during the
