Cool, but not very useful right now, specially given that there's no TV or monitor that can use this feature as of now.
Still, it will be useful in the future once HDMI 2.1 with variable refresh rates gets aproved and TV/monitor manufacturers start to launch models with it.
Please excuse my bad English.
