Basically we have a variable refresh monitor that eliminates tearing, stutter and lag associated with the trade off with vsync on and off. A lot of industry leaders are super excited about the improvement it brings, expecting monitors with it in Q1 2014.

Anandtech is reporting it has a lower bound of 30 fps or stuttering occurs.

It looks good. As a hater of vsync and user of framerate caps I was super interested.

Only problem is that if this just winds up in crappy TN monitors just like 120hz does, it's still a tradeoff of 6 of one and a half dozen of the other compromising on colour and image quality for smoother motion. I'll still take the quality of the actual image on screen over how perceived the smoothness of it is every time.

If they put this in a 30" IPS I will be all over one though.

Well, I have been thinking about a new monitor as I've grown tired of my 120hz for no reason other than I like to spend money.

Perhaps I'll wait for these. If they can put one of these in a 1600p IPS, I just might be interested.

This technology will be available soon on Kepler-based GeForce graphics cards but will require a monitor with support for G-Sync; not just any display will work. The first launch monitor is a variation on the very popular 144 Hz ASUS VG248QE 1920x1080 display and as we saw with 3D Vision, supporting G-Sync will require licensing and hardware changes. In fact, NVIDIA claims that the new logic inside the panels controller is NVIDIA's own design - so you can obviously expect this to only function with NVIDIA GPUs.

Wonder how much the G-sync tax is going to run?

Depending on the cost it could be a double sided sword for sales. It does look like it's possibly a add in card? Guess it could be a with or without option also.

I don't think its something you can retrofit. NVidia was talking about the problems of pixel persistence and controlling the Liquid crystals at a fundamental level. This is going to be a complete replacement for the guts of an LCD monitor and how it not only takes the image from the GPU but how that then drives the voltages to the individual pixels. We'll definitely need to buy new monitors to use it but its supported on Keplar GPUs.

I don't want to give up my Korean 1440p monitor for a TN display, but if this comes to IPS display OR when 4k are < $600, that will definitely be my next monitor.

 

[Black Octagon]

Sounds extremely promising IMHO! But I do agree that it would be a real shame to see this limited to TNs.

I didn't mean a retrofit. If you look at the image it looks like it's a drop in card....As in fits into a slot on the monitors mainboard. More like a replacement for the current controller in the monitor.

I guess I was correct in my thinking

How To Upgrade To G-SYNC

If you&#8217;re as excited by NVIDIA G-SYNC as we are, and want to get your own G-SYNC monitor, here&#8217;s how. Later this year, our first G-SYNC modules will be winging their way to professional modders who will install G-SYNC modules into ASUS VG248QE monitors, rated by press and gamers as one of the best gaming panels available. These modded VG248QE monitors will be sold by the modding firms at a small premium to cover their costs, and a 1-year warranty will be included, covering both the monitor and the G-SYNC module, giving buyers peace of mind.

Beginning later this year, NVIDIA G-SYNC will be available as monitor module you can install yourself, or buy pre-installed in one of the best monitors currently available. Next year, G-SYNC monitors will be available on the shelves of your favorite e-tailers and retailers, in a variety of screen sizes and resolutions, eventually scaling all the way up to 3840x2160 (&#8220;4K&#8221.

Maybe 120 hz PLS/IPS support?!?!?!?

I'll be right there with you in 10 years buddy!

4k really needs to get a standard that includes 120hz as well. Then I wont have any reservations going to it, but I need the frame rate problems fixed before I need the higher density pixels.

 

[Grooveriding]

120hz 4K... see you in 2020.

 

[thilanliyan]

On a technical level I doubt this NEEDS Kepler GPUs, but it is something nV can differentiate with.

120hz 4K... see you in 2020.

Quad Displayport :awe:

Just because the 3d graphics can't be done at 4k 120hz today in games doesn't mean its not useful. I want 144hz on the desktop as well as the higher pixel density. I will probably still play a lot of games at 120hz 1080p on the 4k screen and only older games will really get to run at the top resolution. When the graphics cards catch up such that they can run a lot of modern games then that will change. Bare in mind we are probably only talking 1-2 generations of cards before it becomes a reality. To skip 120hz in the display port standard for 4k is very shortsighted.

 

[SiliconWars]

Interesting, the price will be astronomical no doubt though, and for eyefinity/surround users it'll be even more so.

 

[ICDP]

G-Sync sounds great IMHO. I hate screen tearing and while lag can be reduced with FPS caps and vsync it is always there, so the technology is welcome. Unfortunately if it is Nvidia only it won't be an option as I don't like any hardware that has a vendor lock-out. Any such monitor would need to be open to any GPU vendor for me to consider it as an option.

 

[bystander36]

I've heard this suggestion made a couple times on this forum. Now it is actually coming to fruition. I'm on board.

The 4k panels themselves can >>already do<< 120 hz. The only reason they don't is the electronics and the connector, mostly the connector.

That we haven't had a VESA connector standard out >>before<< 4k was launched boggles my mind.

In case people are clueless to how this works, this is basically a variable refresh rate monitor. This is why it comes with an external power supply (and they are comfortable with offering a DIY solution) instead of being plugged directly into an outlet. The AC adapter will probably feed low voltage DC into the monitor, and there is a frequency generator on the module to adjust the refresh rate depending on the frame rate. This is how you get around both tearing and vsync. I expect the monitor to use even pull-up cadences however when the frame rate falls below 60, otherwise you would get serious eye strain.

Overall a very good solution, and something that should have been done A LONG time ago. For the first time ever, humans should be able to feel refresh rates between common denominators with 100% accuracy. Huge milestone.

 

[bystander36]

Eye strain is not an issue with LCD's. They are solid state. The refresh doesn't cause a flicker, it is simply a matter of updating the image. Lowering the refresh rate will not cause eye strain anymore than having lower FPS on a 60hz monitor does.

I also think this will simply change the refresh to be a hardware call. As it is, monitors refresh at their own pace automatically with no way to control it other than setting it to 60/120hz or what ever. This tech will likely turn off the refresh all together, and simply make a hardware call to refresh. These are not on CRT's, so they are not require to refresh to keep an image displayed. You simply turn on the pixels and they stay on.

 

[VulgarDisplay]

Any eye strain caused by an LCD is due to whatever backlight is in there. If it's flourescent you're more likely to get eye strain. I don't think LED's are as bad.

Ya, though LED's seem to get just as many if not more complaints from those sensitive to backlight flicker. Neither are related to refreshing.

This sounds great! Also should allow for 24fps movies to be viewed correctly on what used to be fixed 60hz monitor.
