VESA launches Adaptive Sync 1.1 certification with tougher requirements for displays

Adaptive Sync is a VESA standard that has been available for years, but that has been put in the front line after the release of technologies AMD FreeSync (AMD’s implementation of this standard) and NVIDIA G-SYNC (Initially with own hardware to later also support Adaptive Sync). This is a technology that allows compatible screens to vary their refresh rate in real time to synchronize with the frames per second generated by the graphics card.

Now, the VESA (Video Electronics Standards Association) has updated the Adaptive Sync standard specifications with the release of Adaptive Sync version 1.1. Although the conventional Adaptive Sync 1.0 standard will remain active and manufacturers will be able to certify their products under that version, Adaptive Sync 1.1 introduces new requirements to provide a better user experience.

This means the inclusion of new, more demanding tests so that a monitor or screen can be certified by VESA. For example, Gray to Gray or GtG response time testing will now be done with a 9×9 test matrix instead of the current 5×5, tripling reaction time testing over 60+ transitions.

Another novelty is that the tests with overdrive are adapted so that they are more similar to how the human eye reacts to light, going from a model of fixed percentages to a method called “Perceptual Quantification”. In total, monitors will have to pass more than 50 tests to get certified.

Monitors with Adaptive Sync certification must offer a minimum frequency range of 60 to 144 Hz, with the minimum being lower and the maximum higher. The response tests must offer an average of less than 5 milliseconds.
