Unfortunately this will be yet another proprietary technology from Nvidia that nobody else will use - which means it won't have mass adoption - which means it's ultimately pointless (unless someone else creates an open source version of it).

NVidia doesn't make displays, so unless you're expecting them to move into that market, your comment doesn't make sense. (Doubly so because this is hardware, not software.) I expect NVidia to license this to monitor manufacturers to drive up demand for 4k-capable video cards.

  NVidia has various contractual arrangements with companies that do make displays to include NVidia-proprietary features though.

> Unfortunately this will be yet another proprietary technology from Nvidia that nobody else will use... This is a scientific/technical research paper for a computer graphics conference. It's not even near being a technology that ships. There's a reason that there are so many "Nvidia only" technologies. Take the G-sync displays for example. It's a problem dating back to cathode ray tube display technology but to overcome it, it takes integration between the display controller hardware (in the graphics card) and the panel control electronics. Display manufacturers do not make the GPU hardware so the only option is for a GPU company to try to make the first step. In the long run some of these technologies will become standard and widespread but someone has to take the first step and that must be economically viable.

  Except what G-sync does is not Nvidia only. What G-sync does is it sends frames at maximum speed (DVI, HDMI, and DP only send frames as fast as absolutely needed to get done in time, ie, at 60hz, it takes approximately 1/60th of a second to send the frame, even if the connection had an available clock rate to send it in 1/144th of a second), and then it sends it on demand instead of at the next frame interval (to reduce latency and jitter). However, before Nvidia announced G-sync (which requires special and expensive hardware), a group of companies lead by AMD submitted an addition to the DisplayPort standard called Freesync which does the same thing using existing hardware (and some monitors already in the wild could be theoretically upgraded to support Freesync with only a firmware update). Nvidia (as a company that makes gamer-grade GPUs) will be required to support Freesync on their GPUs (no existing GeForce can do it according to Nvidia due to HW issues, AMD says Radeons that are GCN should be able to do it with driver updates) because VESA accepted the Freesync proposal and finalized it into the next Displayport spec (VESA/AMD announced it at CES 2014, shortly after Nvidia announced their much more expensive and proprietary G-sync).

    Yes, you are correct. But G-sync (kind of) ships already, you can buy a DIY module to mod a display with it. I'm not aware of any other solutions that would ship yet. I sincerely hope that these proprietary technologies will get put in a standard that will ship with several vendors. All the variable refresh rate demos I've seen look amazing. But the point above still stands, it took the initial effort of the GPU companies to make progress happen on this. It would have been impossible for a display manufacturer, let alone a panel manufacturer to make this happen.
