Manufacturers now use their own measurements so can not necessarily be compared between brands. Examples include LG – Motion Clarity Index (MCI), Samsung – Clear Motion rate (CMR), Philips – Perfect Motion Rate (PMR), Sony – Motionflow XR and Panasonic – BLS (Back Light Scanning). All these figures are twice or more than the traditional 100Hz/200Hz refresh rate figures. No abbreviation indicates traditional measurement. Plasmas generally use a 600Hz sub-field refresh rate.
