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…

Still Limited Availability of Nvidia G-Sync DIY Upgrade Modules

December 28th, 2013 · 4 Comments · General 3D News

Nvidia has promised that by the end of the year they will have the G-Sync DIY Upgrade modules available to the most eager enthusiasts that want to get their hands on the technology as early as possible and they kind of delivered on that promise. The G-Sync DIY upgrade module is intended for owners of ASUS VG248QE monitors that want to upgrade their displays or for people that are interested in buying already upgraded monitors with the module installed by professionals. And I’m saying that they kind of delivered on their promise, because currently there are 4 partners of Nvidia that supposedly offer either an upgrade services to make your ASUS VG248QE monitor G-Sync ready or to sell you an already upgraded monitor. The problem is that all of these four companies are US-based and while with some you might be able to get an overseas delivery, the shipment of a $500 US dollars monitor would end up quite expensive when you add all the taxes on top of the price.

The four Nvidia G-Sync partners that are already announced by Nvidia are:
Falcon Northwest
MAINGEAR
DigitalStorm
Overlord Computer

The first two: Falcon Northwest and MAINGEAR are only selling new computers where you can add a G-Sync modified ASUS VG248QE monitor along with your PC for about $500 US or a bit more. The other two companies DigitalStorm and Overlord Computer can either sell you a new G-Sync modified monitor only for about $500 US or a bit less or modify your own monitor (you need to send it to them) for $299 US or a bit less. The option for purchasing the DIY module only directly and installing it yourself if you are a good technical guy is still not available. Hopefully in January 2014 we are going to see better availability of the G-Sync DIY upgrade modules including availability not only in US, so people that live in Europe and other countries could also have access of the technology and the benefits it offers. Also in the first quarter of the new year we are probably going to see announcements for new G-Sync-enabled monitors, so you might want to wait a bit more and get one of those now anyway…

Nvidia G-SYNC Technology For Better PC Gaming Experience

October 18th, 2013 · 3 Comments · General 3D News

Apparently Nvidia has figured out a way to do a better synchronization between the GPU rendering the frames and the display showing them by adding an additional G-SYNC module inside the display (this means new gaming displays coming out with the module built-in them). The idea is that with this G-SYNC module you are supposedly getting a V-Sync off like experience in terms of responsiveness, but without the tearing of the image displayed on the screen. So less input lag and better responsiveness regardless of the FPS and supposedly no more tearing and stuttering. It all sounds great in theory if you are a gamer, but we need to see it first in action. There is still not a lot of information about this new technology, but hopefully Nvidia will soon provide more technical details…

With G-SYNC, the monitor begins a refresh cycle right after each frame is completely rendered on the GPU. Since the GPU renders with variable time, the refresh of the monitor now has no fixed rate.

This brings big benefits for gamers. First, since the GPU drives the timing of the refresh, the monitor is always in sync with the GPU. So, no more tearing. Second, the monitor update is in perfect harmony with the GPU at any FPS. So, no more stutters, because even as scene complexity is changing, the GPU and monitor remain in sync. Also, you get the same great response time that competitive gamers get by turning off V-SYNC.

The good news is that if you already have a Kepler architecture-based Nvidia GPU you will have the support available for the G-SYNC technology in your computer, so you will only need to get a new monitor with a G-SYNC module built-in. The initial partners that are supposed to offer PC monitors for gamers with the new G-SYNC module are Asus, BenQ, Philips and ViewSonic, all companies that also make 3D Vision compatible displays apart from Philips, and supposedly this extra module will not make the monitor significantly more expensive than a model without the module. There is some information available that the first monitor to support the new technology could be based around the 144Hz-capable ASUS VG248QE that also supports Nvidia’s 3D Vision technology, so G-SYNC hopefully will work just fine with 3D Vision in stereoscopic 3D mode providing even better experience (no word on G-SYNC and 3D Vision support from Nvidia yet). Have in mind though that the technology will be supported over DisplayPort interface only and the first G-SYNC-equipped monitors will probably be available in the first quarter of next year.
