Freesync solution for screen tearing in monitor


What is project FreeSync?

Computer monitors usually refresh at the rate of 60 frames per second. As the contents like video having constant frame rate of 23.976 frames per second, so there is a sync between the video and monitor. But in games, there is never sync in monitor due to variable frame rates, which causes screen tearing. FreeSync is the solution where it sync monitor refresh rates with Games refresh rates. Let’s see how it differs from traditional method to avoid screen tearing ?


An example of  “screen tearing” in dirt 2


In traditional way, problem in games were solved by vertical Synchronization(v-sync).when the v-sync is ON,the computer delivers the frame rate at the monitor’s refresh rate exactly. The content and monitor were sync and the problem were gone.

                                               But when the game is in action, the monitor may not receive new frame from the GPU at it’s refresh cycle, so monitor will display current frame at second time. And here the tear will be seen at higher frame rates, that will result into lag, which will still annoy most of the users while playing Games.

                                                 But AMD has found solution for screen tearing by allowing the monitors frame rate to vary (ex :10-60 times per second) and let the refresh rates controlled by and synchronized to the Graphic cards.This was proposed by AMD to VESA(a standard body for standardizing display specifications) and this technology was accepted by VESA and integrated  into Display port 1.2a specification as “DisplayPort Adaptive-sync”.monitors which will feature Adaptive sync will refresh at the dynamic rates.To utilize the features of such a monitor, you need a graphic card and its driver.

It is same as that of Nvidia’s G-sync technology, but monitor vendors are mostly using AMD Freesync technology for stutter-free display.

project freesync is AMD’s name for the solution: a compatible radeon Graphics card,an AMD catalyst driver and an Adaptive-sync aware display for reducing input latency,abolishing tearing and to eliminate sluttering.

   FreeSync 2

After the Success of  Freesync in Market, AMD have launched Freesync 2 which is having capability to render the games at HDR Quality on monitors in 2017.

FreeSync 2 monitors will harness low-latency, high-brightness pixels, excellent black levels, and a wide color gamut to display High Dynamic Range (HDR) content. In addition, all FreeSync 2 monitors will have support for Low Framerate Compensation (LFC). With Radeon FreeSync 2 technology, gamers can enjoy a complete plug-and-play HDR gaming experience, avoiding the need to tweak settings in software or on the monitor.

FreeSync and FreeSync 2 technologies will co-exist to offer a wide variety of advanced displays to gamers. All FreeSync-compatible Radeon GPUs will support FreeSync 2 technology, including the Radeon RX series GPUs based on the Polaris architecture which also supports DisplayPort HBR3 and enables UltraHD resolution beyond 60Hz. Multiple display vendors are actively evaluating several upcoming products for FreeSync 2 qualification.
