VESA Adds Adaptive-Sync to Popular DisplayPort Video Standard

New Tech­no­lo­gy Enab­les Smoot­her Gaming, Lower Power and
Effi­ci­ent Dis­play of Con­tent Ren­de­red at a Wide Ran­ge of Frame Rates –

NEWARK, CA (12 May 2014) – The Video Elec­tro­nics Stan­dards Asso­cia­ti­on (VESA®) today announ­ced the addi­ti­on of ‘Adap­ti­ve-Sync’ to its popu­lar Dis­play­Po­rt™ 1.2a video inter­face stan­dard. This tech­no­lo­gy deli­vers several important capa­bi­li­ties to com­pu­ter users: Adap­ti­ve-Sync pro­vi­des smoot­her, tear-free images for gaming and jud­der-free video play­back. It also signi­fi­cant­ly redu­ces power con­sump­ti­on for sta­tic desk­top con­tent and low frame rate video.

Com­pu­ter moni­tors nor­mal­ly refresh their dis­plays at a fixed frame rate. In gaming app­li­ca­ti­ons, a computer’s CPU or GPU out­put frame rate will vary accord­ing to the ren­de­ring com­ple­xi­ty of the image. If a display’s refresh rate and a computer’s ren­der rate are not syn­chro­ni­zed, visu­al artifacts—tearing or stuttering—can be seen by the user. Dis­play­Po­rt Adap­ti­ve-Sync enab­les the dis­play to dyna­mi­cal­ly match a GPU’s ren­de­ring rate, on a frame-by-frame basis, to pro­du­ce a smoot­her, low laten­cy, gaming experience.

In app­li­ca­ti­ons whe­re the dis­play con­tent is static—such as sur­fing the web, rea­ding email, or viewing a sli­de presentation—DisplayPort Adap­ti­ve-Sync allows the dis­play refresh rate to be redu­ced seam­less­ly, lowe­ring sys­tem power and exten­ding bat­te­ry life.

During the play­back of lower frame rate video con­tent, Adap­ti­ve-Sync allows the source to opti­mi­ze trans­port of the video for­mat lever­aging OS and Dis­play­Po­rt inter­faces.   In addi­ti­on to pro­vi­ding smoot­her video play­back, the lower frame rate enab­led by Adap­ti­ve-Sync also redu­ces power demand, exten­ding bat­te­ry life.

Dis­play­Po­rt Adap­ti­ve-Sync enab­les a new approach in dis­play refresh tech­no­lo­gy, ” said Syed Athar Hus­s­ain, Dis­play Domain Archi­tect, AMD and VESA Board Vice Chair­man. “Ins­tead of updating a moni­tor at a con­stant rate, Adap­ti­ve-Sync enab­les tech­no­lo­gies that match the dis­play update rate to the user’s con­tent, enab­ling power effi­ci­ent trans­port over the dis­play link and a flu­id, low-laten­cy visu­al experience.”

Adap­ti­ve-Sync is a pro­ven and wide­ly adop­ted tech­no­lo­gy. The tech­no­lo­gy has been a stan­dard com­po­nent of VESA’s embed­ded Dis­play­Po­rt (eDP™) spe­ci­fi­ca­ti­on sin­ce its initi­al roll­out in 2009. As a result, Adap­ti­ve-Sync tech­no­lo­gy is alrea­dy incor­po­ra­ted into many of the buil­ding block com­pon­ents for dis­plays that rely on eDP for inter­nal video signa­ling. New­ly intro­du­ced to the Dis­play­Po­rt 1.2a spe­ci­fi­ca­ti­on for exter­nal dis­plays, this tech­no­lo­gy is now for­mal­ly known as Dis­play­Po­rt Adaptive-Sync.

VESA is con­stant­ly eva­lua­ting new methods and tech­no­lo­gies that add value to both the end user and our OEM mem­ber com­pa­nies. Adap­ti­ve-Sync deli­vers clear­ly visi­ble advan­ta­ges to the user for gaming and live video, and con­tri­bu­tes to the deve­lo­p­ment of slee­ker mobi­le sys­tem designs by redu­cing bat­te­ry power requi­re­ments, ”said Bill Lem­pe­sis, VESA Exe­cu­ti­ve Direc­tor. “VESA has deve­lo­ped a test spe­ci­fi­ca­ti­on to cer­ti­fy Adap­ti­ve-Sync com­pli­an­ce. Sys­tems that pass Adap­ti­ve-Sync com­pli­an­ce tes­ting will be allo­wed to fea­ture the offi­cial Adap­ti­ve-Sync logo on their pack­a­ging, informing con­su­mers which Dis­play­Po­rt-cer­ti­fied dis­plays and video sources offer Adaptive-Sync.”

Imple­men­ta­ti­on of Dis­play­Po­rt Adap­ti­ve-Sync is offe­red to VESA mem­bers without any licen­se fee.
