    Default VESA Adds Adaptive-Sync To DisplayPort 1.2a Specification

    Phoronix: VESA Adds Adaptive-Sync To DisplayPort 1.2a Specification

    The VESA association has added "Adaptive-Sync" to the DisplayPort 1.2a video interface specification. Adaptive-Sync is a vendor-neutral way of having a dynamic/adaptive refresh-rate and similar to NVIDIA's G-Sync...

    Default Standards

    This is great news. It means that once DP 1.2a is out on monitors and GPUs that a lot of tearing will go away. I've had all kinds of videos and video games (mostly via Steam) tear quite a lot. On NVidia, AMD, and Intel GPUs. This being part of the standard means that any 1.2a hardware will have to support it, and that's great news for everyone.

    So it begins. A new age of tearless gaming. What will NVIDIA be able to offer more with their G-SYNC compared to this?

    Availability two years earlier than VESA?

    Hold off buying that new monitor until the dust settles!

    +1. DisplayPort 1.3 is coming out soon anyways. It should have this + 8k bandwidth incorporated.

    I actually don't like this feature. Smoothness of animation is achieved by a constant refresh rate. Adaptive refresh rate is going to cause jittery animation.

    Do they have to do anything? It is an open standard. They don't need to sell tacked on proprietary chips for monitors when they just naturally handle adaptive vsync anyway. It is kind of like Mantle - bring out a closed arbitrary piece of shit, and motivate the open standards to get off their asses and adopt necessary technological improvements.

    The hardware will require a bigger buffer and probably more processing. I would expect a 50-100$ premium to start with prices stabilizing as more vendors enter the market.

    50-100$ premium seems very high to me. The requirements for Adaptive-Sync are only a new scaler ASIC and passing the compliance test (if you want to carry the logo). The cost of the scaler ASIC is only a very small part of the monitor's bill of materials.

    Keep in mind that Adaptive-Sync has been around in the eDP standard since 2009, and it certainly didn't make laptop displays cost $50-100 more.
