VESA adds AMD’s Freesync as Adaptive-Sync to displayport standard

The VESA has announced that the Freesync standard from AMD, which monitors with a variable refresh rate can be controlled, it will record in the displayport 1.2 a standard. The technology is now Adaptive-Sync is called.

AMD presented the Freesync technology earlier this year at the CES fair, as a counterpart of the proprietary G-Sync technology from competitor Nvidia. Freesync makes use of existing VESA standard to the vblank intervals, so that on compatible displays variable verversingssnelheden possible. This must be tearing and stuttering when gaming to prevent. The technology is also interesting for showing videos. Thus, the judder-issues of video material with typical frame rates of 24 and 25fps on 60Hz monitors prevent. Also can lower frame rates for static content, for example, a laptop is of benefit to the battery life.

The VESA has Freesync is now included in the displayport 1.2 a standard, although implementation of the technology is not required. The technology was was already included in the embedded displayport specification, allowing for some integrated hardware for example, the video display on laptops is already compatible with the technology. Also has the VESA the name of the technology changed in Adaptive-Sync.

With the implementation of Freesync hopes to VESA that the technology wider will be implemented, than G-Sync, for which licensing fees to Nvidia to be paid for. AMD thinks that in six to twelve months the first monitors on the market that are compatible with Adaptive-Sync and VESA certified. In addition, a suitable Radeon-video card or AMD apu is needed. AMD calls Radeon R9 290X, R9 290, R7 260X and R7 260 as the compatible graphics cards and apus with the code names Kabini, Temash, Beema and Mullins also need to work.

The gpu or apu must have a compatible monitor can recognize and then minimum and maximum beeldverversingssnelheden to define. Among other things, the frequency bands 36-240Hz, 21-144Hz, 17-120Hz and 9-60Hz are possible. The chipbakker let know also soon support for Adaptive-Sync to its Catalyst-videodrivers to add.
