A Little Bit More Details About the Nvidia G-SYNC Technology

January 6th, 2014 · 3 Comments · General 3D News

Just a few days ago I was talking about Nvidia’s G-SYNC technology and the fact that the early DIY upgrade modules are still not widely available, not to mention that there was also not a lot of information regarding the first wave of monitors that are supposed to come out with G-SYNC support built-in. Well, in the Nvidia CES Press Event the company has revealed a bit more information about the G-SYNC tech, namely the Q2 availability from Acer, AOC, ASUS, BEnQ, Philps and ViewSonic. And on the slide that Nvidia’s CEO Jen-Hsun Huang has shown you can also see that we are getting not only 24″ and 27″ displays with 1080p resolution that will support G-SYNC, but there will be also 27-inch models with 2560×1440 resolution. There is no hint however if these higher resolution models will feature higher refresh rate than 60Hz or if there will be 3D Vision support, in fact there was nothing about 3D Vision mentioned along with the G-SYNC talk in the press event, though the G-SYNC part was not the main focus either. We already know that Nvidia’s G-SYNC technology is compatible with 3D Vision, but the two technologies can be available and work separately as well, so there is no guarantee that we are going to see higher resolution displays with stereoscopic 3D support coming with G-SYNC support as well. The same goes for 120Hz or 144Hz refresh rate on displays with resolution higher than Full HD that, even though the Display Port interface used for G-SYNC is already capable of supporting this, so we’ll have to wait and see when display manufacturers start announcing their new products with G-SYNC technology later this year.

Meanwhile if you are interested in more details about the G-SYNC DIY Upgrade modules – what they are and how they are installed, then you might want to take a look at the review that the guys at PC Perspective have just published. In it they show in quite a lot details what the upgrade kit is and the installation process, though unfortunately you still cannot get the module only and install it yourself as so far it is only been offered though just a few companies that provide the installation service or sell you an already modified product. I’ve already discussed the official Nvidia partners in a previous post, so I’ll just mention the fact that the G-SYNC DIY Upgrade Kits are still only available in US. And with the just announced expected Q2 availability of monitors with built-in G-SYNC support you might want to wait for these to become available, than to consider getting an upgrade kit or modified version of the ASUS VG248QE monitor…

The New Nvidia G-SYNC Technology Will Support 3D Vision as Well

October 19th, 2013 · 10 Comments · GeForce 3D Vision

Some good news for 3D Vision users, the just announced Nvidia G-SYNC technology will also work in stereoscopic 3D mode when playing games with 3D Vision as well by eliminating screen tearing, input lag, and stutter. All you will need to do is have a Kepler-based graphics card like at least GeForce GTX 650 Ti Boost and get a G-SYNC-enabled monitor or get a DIY Upgrade kit for an ASUS VG248QE monitor if you already have the monitor available. Nvidia says that the first DIY Upgrade modules will be shipping later this year for the most eager users willing to try the new technology. The Nvidia G-SYNC Do-it-yourself kit will cost approximately $175 USD and come with 1 year warranty. And next year we are supposedly going to see new models coming out on the market with built-in G-SYNC modules from Asus, BenQ, Philips and ViewSonic with displays even going up to 4K resolution.

Nvidia G-SYNC requires Microsoft Windows 7, 8 or 8.1 and apparently older versions of the OS will not be supported and of course it will only work with compatible Nvidia-based GPUs and G-SYNC enabled monitors, so no go for AMD graphics with a G-SYNC monitor. Multi-monitor surround configurations will also be supported if you have all G-SYNC-enabled monitors, as well as SLI setups with multiple Kepler-based GPUs that meet the minimum requirements for G-SYNC to work. G-SYNC is supposed to work with all games, though apparently some games might have issues and Nvidia will be giving the user the ability to disable G-SYNC from the control panel of the drivers on per game basis. Also games that Nvidia discovers that have trouble with G-SYNC will be disabled by default in the driver (more game profiles) and the video driver needs to be version 331.58 or higher (not yet publicly released) in order for you to have G-SYNC support available.

Note that after installing an Nvidia G-SYNC module in the ASUS VG248QE monitor and this should be also true for the upcoming monitors with the module built-in you are going to be able to use it only through the DisplayPort interface with no audio being transmitted along the video signal. Apparently only the Display Port interface allows for the tear-free, faster and smoother variable fps to be achieved when synchronizing the monitor to the output of the GPU, instead of the GPU to the monitor. Also note that the minimum refresh rate with the G-SYNC module will be 30 fps, so apparently even at 30 frames per second thing should feel very smooth and responsive all the way up to the maximum refresh rate of the monitor with in the case of the ASUS VG248QE is 144Hz.

The good news for 3D Vision users is that since the new G-SYNC technology will be compatible with 3D Vision and will also benefit from being available on monitors able to deliver 120Hz and 144Hz we are also going to see more new displays with 3D Vision supported being released. And hopefully Nvidia will start pushing 3D Vision again along with the G-SYNC technology instead on focusing only on G-SYNC. I don’t know about you, but I’m already eager to see the G-SYNC in action with 3D Vision…
