    This is great!
    ... for someone else lol, I've bought all the displays I'm going to for quite a few years.

    While I like the idea of permanently solving tearing, lagging and stuttering, I don't like the idea of buying specific monitors for it. This might have potential, but considering 120Hz monitors still aren't popular, I don't see this becoming popular either. Meaning it will be really limited choice of screens. Asus, Philips, BenQ and ViewSonic, are also the brands that have released "120Hz 3D Vision Ready" monitors... Those brands have about 6 different models spread out over those 4 brands, all 24" and 27" 1920x1080 screens with about 300$ starting price.

    They should have made this technology freely licenseable and still reap the benefits. Now they made a proprietary technology combined with proprietary hardware, just like their 3D Vision tech (although requiring one more hardware bit).

    I like the idea, I hate the execution.

    Yeah, I would have preferred a video card-based solution (drivers or additional hardware on the card) that works with every monitor.

    Indeed. An Nvidia card with much better lag/stutter/tear is a very good selling point. But requiring a specific monitor too seems to vendor-lock you in. So what if in two years you want an AMD GPU ? Your screen will just be plain ol' normal and even if AMD comes with competing technology, it probably won't work since Nvidia isn't keen on inviting others into their party.

    Oh gawd yes, I've been waiting for this forever. It was kind of obvious that lcd didn't need a refresh rate like the old analog scan-based CRTs.

    This doesnt change the requirement for a refresh rate.

    Actually the G-SYNC is a module you can purchase to mod your own monitor with assuming the monitor is capable (Right now the ASUS VG248QE is capable of installing the G-SYNC module, all you need is a phillips screw driver to take apart the panel housing)

    The other option is to buy the G-SYNC professionally modded panel for a premium with 1yr warranty over the standard VG248QE price.

    Isn't there something like that already? You know... V-Sync...

    Wow this is actually impressive. I'm speechless, I didn't think LCD monitors could switch refresh rate fast enough for this kind of thing to work. Honest to God I'll be buying one of those monitors no matter the price. This absolutely perfect smoothness is an old dream of mine. I don't know if they will also require you to change GPU (I mean, upgrade to a new gen since I already have a nvidia GPU) but if I have to I will.

    Are you serious? V-syinc has so many shortcomings this is not even comparable.

    He said he wanted something that works on every monitor, V-Sync is it.

    Most monitors are really slow at switching refresh rate/resolution so that's probably why.

    Sorry, didn't really read what you were replying to :)

    This is great! Thank you Nvidia. Can't wait to see this in person. Hopefully they will have it at next years Quakecon.

    Add me to the "I like the idea, but not the solution" camp. I wish this was something that would work for existing devices.
    For now I'll just rock vsync and a framerate limiter of some kind.

    It looks good. Sadly I prefer the benefits of an IPS monitor to these TNs. Also I'm just not that sensitive to tearing as others here. Well we'll see what the fall out of this is but since it is hardware (Requiring both a 650 ti boost and either module or a new monitor) I just don't see a ton of traction, but of course I could be wrong. I wonder what the marketing will look like

    would have preferred a PCIe slot card like their Quadro Sync version, instead of a monitor hack. goodbye monitor warranty.
    Nvidia also needs to fully port their Quadro Mosaic to Geforce Surround.

    That's unfortunately not possible.

    Vsync 'enables' synchronous display updates. This is for asynchronous display update.

    Note that this will only fix stutters of the sub-refresh rate dip variety. This technology won't eliminate any stuttering inherent in uneven frame pacing.

    Hopefully someone will mention if this adds any input lag. I would love to use vsync but the input lag you get with vsync is horrendous for proper FPS play.

    If this makes it buttery smooth and adds no additional input lag this would be awesome. (If it's the monitors changing their refresh rate dynamically hopefully it doesn't)

    Can something like this be incorporated into other monitor types besides just TN?

    Cool stuff, though I can't go back to a 1080p TN. I hope one of these monitors coming next year has this combined with some sort of motion blur reduction tech like 2d lightboost in a resolution higher than 1080p. Then we might finally have a monitor worthy of being called a true upgrade from the old CRTs.

    ...and shouldn't this be in the 'Display' forum?

    I don't see why it couldn't. They're just targeting gaming-oriented displays, I guess, which means TN.

    Yes, nVidia only.... but it should be in the display forum.

    No, both V-Sync and G-Sync are synchronous configurations. The only difference is the sync source.

    With V-Sync, the graphics card's output is synced to the monitor's refresh rate.
    With G-Sync, the monitor's refresh rate is synced to the graphics card's output.

    Biggest advantage to G-Sync is that framerate no-longer has to be a multiple of the monitor's refresh rate in order to eliminate tearing.

    Awesome...

    Did anyone catch what the max resolution will be at launch for these boards? I'd love to hook one into my 2560x1440 110hz PLS display.

    The display updates are asynchronous to any fixed update interval.

    No. The display updates are synchronous to the update interval defined by the graphics card's framerate.

    Just because the sync rate varies does not mean the two devices run asynchronously...

    The monitor refreshes every time there is a new completed frame (and ONLY when there is a new completed frame). That's about as synchronous as you can get.

    it would be nice if this became a standard on ALL devices.

    not sure how it would work with projectors, specifically DLP, however still would be nice to have this on all monitors :)

    otherwise pretty damn cool concept

    Destined to be another niche like 3d monitors. This is where all those tegra chips no one bought went btw.

    +1. I do not like the idea of buy specific monitors to enjoy that... but bring out that idea that maybe in the future we could see a card based solution?.
