VESA Wants To Make Motion Blur Official With ClearMR

Would You Welcome A Clear Motion Ratio Spec?

There is currently no standard to measure the motion blur on a display, though many sites like and who have become very good at measuring motion blur in their reviews.  Those resources are a great help, but it might be nice to have an official rating similar to HDR which consumers can easily refer to at purchase.   Then again, there have been some shenanigans on some monitors HDR rating; hopefully this can be avoided in ClearMR.

Motion blur is a little more complicated than HDR as it is a combination of the monitor’s refresh rate, adaptive or not, as well as the response time.   If the time it takes for a pixel to shift is not in sync with the refresh rate then you get what is called motion blur.   VESA would like to see the adoption of their Clear Motion Ratio Compliance Test Specification which would measure the ratio of clear pixels to blurry ones and assign them a rating from ClearMR 3000 to ClearMR 9000.   Ars Technica provides the example of ClearMR 7000, which has a “Clear Motion Ratio” range of 6,500 to 7,500, so the clear-to-blurry pixel ratio would be 65 to 75 times more clear pixels than blurry ones.

This is still a bit of a work in progress, VESA’s ClearMR can deal with displays that have overdrive features, but as of yet only SDR is supported.  Find more details in this article.
