G-Sync is Dead. VESA Adds Adaptive-Sync to DisplayPort Standard

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.
 
Checkout my doubles.
Doubles and this thread goes down hill fast.

oh wait, wrong part of the Internets. i have not traveled to that part of the internet to wade in fecal matter in a long time.

Erm, why necro post a news article from over a year ago?
Here we are a year on and gsync is well dead. No, wait...

Article is year old but the latest I heard is Intel are supporting this VESA standard so G-sync may die eventually or else we'll have two standards making life difficult.

We knew it was to be added to Vesa spec. but nvidia still seem determined not to support it.

They want to lock people into their proprietary technology so they can make more money, literally the only thing stopping them supporting open standards. With Intel supporting adaptive sync, I hope it destroys their g-sync division.

The more companies that support Adaptive-sync the better, will put pressure on Nvidia to support it. If someone that has a g-sync monitor moves to AMD they can't use Freesync, yet if someone that owns an AMD GPU + Freesync monitor wants to downsize and just use an Intel iGPU with Adaptive-sync they can.

Not yet they can't, there's no set date for a solution to use with adaptive sync, or what IGP's etc.

Not just that, but how many motherboards have Display Port (Support is sporadic at best on a handful of boards I looked at)? People don't seem to ever think further than a headline.
 
As I've just posted in the other thread, it might be one or two generations before Intel have a product that supports Adaptive-Sync, Freesync might not be around by then.
 
Why do the Nvidia crew get so wound up when a potential tech that could make it into all monitors and change gaming for everyone is promoted? Who cares if proprietary G-sync lives or dies, as long as the open standard Adaptive sync is widely accepted.

We all know G-sync will never make it into all monitors simply due to Nvidia's policies of keeping it in premium products.

To my understanding GSync will (until hardware changes) be superior due to its ability to store additional buffers - allowing for better latency in low, changing, framerate situations and while it probably won't ever be quite perfect without low level OS + hardware integration support for 3D in a window modes amongst 1-2 other features the gsync module allows for that the standard hardware with adaptive sync support doesn't.

I haven't tried either Free or G but from what I've read G-sync does a better job of it than Free-sync does but that comes with an additional price.
It seems that the main reason G is better is down to the monitor manufacturers not using the better suited components. If they was using the right bits so that the monitor could give us a full 30 -144 working range it would be a lot better and I imagine most of us would prefer that even if it meant paying a bit extra.

As an example look at the new 27" IPS Free and G panels, There's a 200 quid difference between the ROG Free panel and the Predator G panel. And in my opinion the cheaper one is the better brand that's usually the pricier of the two. I'd happily pay another 100 quid to it for a better working range, That'd still leave it 100 quid cheaper.
