2.6 Quick Media Switching

In the past, when playing video contents that have different refresh rate, there was a short blackout as the HDMI sink needs to re-sync its refresh rate when different video content is switching. The Quick Media Switching (QMS) eliminates the blackout caused by refresh rate changes and allows the end user to watch content with differing refresh rates back-to-back without the blackout.
