Nvidia's G-Sync technology is pretty neat; it discards the fixed refresh rate of traditional displays and instead updates the screen as new frames are produced by the graphics card. This synchronization eliminates tearing and stuttering, and Scott was very impressed with the results. There is a catch, however. G-Sync requires a Kepler-class GPU and a monitor infused with custom Nvidia hardware.
The first display to support G-Sync is Asus' VG248QE. A native G-Sync version is due next year, and modified variants of the exiting model are making the rounds at tech review sites. Scott has been playing with one in Damage Labs, in fact. And now you have a chance to buy one for yourself. Asus and Nvidia are selling a limited number of modified VG248QE monitors through a select group of system builders.
Digital Storm, Falcon Northwest, Maingear, and Overlord Computer will all be offering the G-Sync-enabled display. The Maingear and Overlord links are dead as I write this, but we do have details on the other vendors. Digital Storm is selling pre-modified monitors for $499, and it'll upgrade an existing VG248QE display for $299. Falcon Northwest is also selling modded displays. However, they're only available to folks buying complete systems or those who have purchased Falcon rigs previously.
We were told in October than the native G-Sync version of the VG248QE would sell for $399, so the modded screen is priced at a premium. Falcon notes that part of the additional cost can be attributed to the labor associated with the modification process. The G-Sync module also replaces some of the monitor's existing electronics, which won't be necessary in the native version.
Unfortunately, the G-Sync kit isn't sold separately right now. Stay tuned for an opportunity to win one for yourself, though. Scott will also have more to say about the technology soon.
In the meantime, you can check out a new promo video highlighting G-Sync's benefits. The refresh-matching tech can only be simulated on a conventional display, so there are some caveats attached to the clip. The video has a 60-FPS frame rate; to get the full effect, you'll need a 60Hz monitor and a video player capable of maintaining that frame rate. You'll also want to download the 200MB file and play it locally rather than attempting to stream the footage. We've tried watching the video on several systems, and we're still seeing some occasional skipping, but the clip still gets the point across.
