◆ GetVRRRange()

MythVRRRange MythEDID::GetVRRRange ( ) const

Return the range of supported refresh rates.

If the VRR range is explicit in the EDID then the third element of MythVRRRange is set to true, otherwise 'false' indicates that the VRR range is assumed from the vertical refresh range indicated in the EDID. In both cases the behaviour of the display below any minimum is undefined (e.g. there is no current indication whether the display supports 'FreeSync Premium' - in which case low frame rates may produce significant jitter).
