A few days with some magic monitors

Last month friend of the site and technology enthusiast Tom Petersen, who apparently does SOMETHING at NVIDIA, stopped by our offices to talk about G-Sync technology. A variable refresh rate feature added to new monitors with custom NVIDIA hardware, G-Sync is a technology that has been frequently discussed on PC Perspective

The first monitor to ship with G-Sync is the ASUS ROG Swift PG278Q - a fantastic 2560x1440 27-in monitor with a 144 Hz maximum refresh rate. I wrote a glowing review of the display here recently with the only real negative to it being a high price tag: $799. But when Tom stopped out to talk about the G-Sync retail release, he happened to leave a set of three of these new displays for us to mess with in a G-Sync Surround configuration. Yummy.

So what exactly is the current experience of using a triple G-Sync monitor setup if you were lucky enough to pick up a set? The truth is that the G-Sync portion of the equation works great but that game support for Surround (or Eyefinity for that matter) is still somewhat cumbersome.

In this quick impressions article I'll walk through the setup and configuration of the system and tell you about my time playing seven different PC titles in G-Sync Surround.

Earlier today we had NVIDIA's Tom Petersen in studio to discuss the retail availability of G-Sync monitors as well as to get hands on with a set of three ASUS ROG Swift PG278Q monitors running in G-Sync Surround! It was truly an impressive sight and if you missed any of it, you can catch the entire replay right here.

Even if seeing the ASUS PG278Q monitor again doesn't interest you (we have our full review of the monitor right here), you won't want to miss the very detailed Q&A that occurs, answering quite a few reader questions about the technology. Covered items include:

  • Potential added latency of G-Sync
  • Future needs for multiple DP connections on GeForce GPUs
  • Upcoming 4K and 1080p G-Sync panels
  • Can G-Sync Surround work through an MST Hub?
  • What happens to G-Sync when the frame rate exceeds the panel refresh rate? Or drops below minimum refresh rate?
  • What does that memory on the G-Sync module actually do??
  • A demo of the new NVIDIA SHIELD Tablet capabilities
  • A whole lot more!

Another big thank you to NVIDIA and Tom Petersen for stopping out our way and for spending the time to discuss these topics with our readers. Stay tuned here at PC Perspective as we will have more thoughts and reactions to G-Sync Surround very soon!!

Tomorrow at 12pm EDT / 9am PDT, NVIDIA's Tom Petersen will be stopping by the PC Perspective office to discuss some topics of interest. There has been no lack of topics floating around the world of graphics card, displays, refresh rates and tablets recently and I expect the show tomorrow to be incredibly interesting and educational.

On hand we'll be doing demonstrations of G-Sync Surround (3 panels!) with the ASUS ROG Swift PG278Q display (our review here) and also show off the SHIELD Tablet (we have a review of that too) with some multiplayer action. If you thought the experience with a single G-Sync monitor was impressive, you will want to hear what a set of three of them can be like.

Richard Huddy Discusses FreeSync Availability Timeframes

At SIGGRAPH, Richard Huddy of AMD announced the release windows of FreeSync, their adaptive refresh rate technology, to The Tech Report. Compatible monitors will begin sampling "as early as" September. Actual products are expected to ship to consumers in early 2015. Apparently, more than one display vendor is working on support, although names and vendor-specific release windows are unannounced.

As for cost of implementation, Richard Huddy believes that the added cost should be no more than $10-20 USD (to the manufacturer). Of course, the final price to end-users cannot be derived from this - that depends on how quickly the display vendor expects to sell product, profit margins, their willingness to push new technology, competition, and so forth.

If you want to take full advantage of FreeSync, you will need a compatible GPU (look for "gaming" support in AMD's official FreeSync compatibility list). All future AMD GPUs are expected to support the technology.

G-SYNC is sweet but far from free

Ryan was not the only one to test the ASUS ROG Swift PG278Q G-Sync monitor, Overclockers Club also received a model to test out.  Their impressions of the 27" 2560 x 1440 TN panel were very similar, once they saw this monitor in action going back to their 30-inch 60Hz IPS monitor was not as enjoyable as once it was.  The only bad thing they could say about the display was the MSRP, $800 is steep for any monitor and makes it rather difficult to even consider getting two or more of them for a multiple display system.

”When you get down to it, the facts are that even with a TN panel being used for the high refresh rate, the ASUS ROG Swift PG278Q G-Sync monitor delivers great picture quality and truly impressive gaming. I could go on all day long about how smooth each of the games played while testing this monitor, but ultimately not be able to show you without having you sit at the desk with me. No stuttering, no tearing, no lag; it's like getting that new car and having all the sales hype end up being right on the money. When I flip back and forth between my 60Hz monitor and the PC278Q, its like a night and day experience.”

The Waiting Game

NVIDIA G-Sync was announced at a media event held in Montreal way back in October, and promised to revolutionize the way the display and graphics card worked together to present images on the screen. It was designed to remove hitching, stutter, and tearing -- almost completely. Since that fateful day in October of 2013, we have been waiting. Patiently waiting. We were waiting for NVIDIA and its partners to actually release a monitor that utilizes the technology and that can, you know, be purchased.

In December of 2013 we took a look at the ASUS VG248QE monitor, the display for which NVIDIA released a mod kit to allow users that already had this monitor to upgrade to G-Sync compatibility. It worked, and I even came away impressed. I noted in my conclusion that, “there isn't a single doubt that I want a G-Sync monitor on my desk” and, “my short time with the NVIDIA G-Sync prototype display has been truly impressive…”. That was nearly 7 months ago and I don’t think anyone at that time really believed it would be THIS LONG before the real monitors began to show in the hands of gamers around the world.

Since NVIDIA’s October announcement, AMD has been on a marketing path with a technology they call “FreeSync” that claims to be a cheaper, standards-based alternative to NVIDIA G-Sync. They first previewed the idea of FreeSync on a notebook device during CES in January and then showed off a prototype monitor in June during Computex. Even more recently, AMD has posted a public FAQ that gives more details on the FreeSync technology and how it differs from NVIDIA’s creation; it has raised something of a stir with its claims on performance and cost advantages.

That doesn’t change the product that we are reviewing today of course. The ASUS ROG Swift PG278Q 27-in WQHD display with a 144 Hz refresh rate is truly an awesome monitor. What did change is the landscape, from NVIDIA's original announcement until now.

AMD Releases FreeSync Information as a FAQ

Subject: General Tech, Graphics Cards, Displays | July 29, 2014 - 06:02 PM |
Tagged: vesa, nvidia, g-sync, freesync, DisplayPort, amd

Dynamic refresh rates have two main purposes: save power by only forcing the monitor to refresh when a new frame is available, and increase animation smoothness by synchronizing to draw rates (rather than "catching the next bus" at 16.67ms, on the 16.67ms, for 60 Hz monitors). Mobile devices prefer the former, while PC gamers are interested in the latter.

Obviously, the video camera nullifies the effect.

NVIDIA was first to make this public with G-Sync. AMD responded with FreeSync, starting with a proposal that was later ratified by VESA as DisplayPort Adaptive-Sync. AMD, then, took up "Project FreeSync" as an AMD "hardware/software solution" to make use of DisplayPort Adaptive-Sync in a way that benefits PC gamers.

Today's news is that AMD has just released an FAQ which explains the standard much more thoroughly than they have in the past. For instance, it clarifies the distinction between DisplayPort Adaptive-Sync and Project FreeSync. Prior to the FAQ, I thought that FreeSync became DisplayPort Adaptive-Sync, and that was that. Now, it is sounding a bit more proprietary, just built upon an open, VESA standard.

If interested, check out the FAQ at AMD's website.

AMD Demonstrates Prototype FreeSync Monitor with DisplayPort Adaptive Sync Feature

Subject: Graphics Cards, Displays | June 3, 2014 - 09:40 PM |
Tagged: gsync, g-sync, freesync, DisplayPort, computex 2014, computex, adaptive sync

AMD FreeSync is likely a technology or brand or term that is going to be used a lot between now and the end of 2014. When NVIDIA introduced variable refresh rate monitor technology to the world in October of last year, one of the immediate topics of conversation was the response that AMD was going to have. NVIDIA's G-Sync technology is limited to NVIDIA graphics cards and only a few (actually just one still as I write this) monitors actually have the specialized hardware to support it. In practice though, variable refresh rate monitors fundamentally change the gaming experience for the better

freesync1.jpg

At CES, AMD went on the offensive and started showing press a hacked up demo of what they called "FreeSync", a similar version of the variable refresh technology working on a laptop. At the time, the notebook was a requirement of the demo because of the way AMD's implementation worked. Mobile displays have previously included variable refresh technologies in order to save power and battery life. AMD found that it could repurpose that technology to emulate the effects that NVIDIA G-Sync creates - a significantly smoother gaming experience without the side effects of Vsync.

Our video preview of NVIDIA G-Sync Technology

Since that January preview, things have progressed for the "FreeSync" technology. Taking the idea to the VESA board responsible for the DisplayPort standard, in April we found out that VESA had adopted the technology and officially and called it Adaptive Sync

So now what? AMD is at Computex and of course is taking the opportunity to demonstrate a "FreeSync" monitor with the DisplayPort 1.2a Adaptive Sync feature at work. Though they aren't talking about what monitor it is or who the manufacturer is, the demo is up and running and functions with frame rates wavering between 40 FPS and 60 FPS - the most crucial range of frame rates that can adversely affect gaming experiences. AMD has a windmill demo running on the system, perfectly suited to showing Vsync enabled (stuttering) and Vsync disabled (tearing) issues with a constantly rotating object. It is very similar to the NVIDIA clock demo used to show off G-Sync.

freesync2.jpg

The demo system is powered by an AMD FX-8350 processor and Radeon R9 290X graphics card. The monitor is running at 2560x1440 and is the very first working prototype of the new standard. Even more interesting, this is a pre-existing display that has had its firmware updated to support Adaptive Sync. That's potentially exciting news! Monitors COULD BE UPGRADED to support this feature, but AMD warns us: "...this does not guarantee that firmware alone can enable the feature, it does reveal that some scalar/LCD combinations are already sufficiently advanced that they can support some degree of DRR (dynamic refresh rate) and the full DPAS (DisplayPort Adaptive Sync) specification through software changes."

freesync3.jpg

The time frame for retail available monitors using DP 1.2a is up in the air but AMD has told us that the end of 2014 is entirely reasonable. Based on the painfully slow release of G-Sync monitors into the market, AMD has less of a time hole to dig out of than we originally thought, which is good. What is not good news though is that this feature isn't going to be supported on the full range of AMD Radeon graphics cards. Only the Radeon R9 290/290X and R7 260/260X (and the R9 295X2 of course) will actually be able to support the "FreeSync" technology. Compare that to NVIDIA's G-Sync: it is supported by NVIDIA's entire GTX 700 and GTX 600 series of cards.

freesync4.jpg

All that aside, seeing the first official prototype of "FreeSync" is awesome and is getting me pretty damn excited about the variable refresh rate technologies once again! Hopefully we'll get some more hands on time (eyes on, whatever) with a panel in the near future to really see how it compares to the experience that NVIDIA G-Sync provides. There is still the chance that the technologies are not directly comparable and some in-depth testing will be required to validate.

Computex 2014: Acer XB280HK Is 28-inch 4K with G-Sync

Subject: General Tech, Displays, Shows and Expos | June 2, 2014 - 12:27 PM |
Tagged: XB280HK, g-sync, computex 2014, computex, acer, 4k

Speaking of G-Sync monitors, Acer has announced a 4K monitor ahead of Computex with NVIDIA's adaptive refresh rate technology. While they do not ever say that it is 60Hz, I believe that it is. It also seems to be based on a TN panel. It, being G-Sync, connects with DisplayPort 1.2 and also includes four USB 3.0 ports. It, however, does not seem to support the competing AMD's FreeSync, integrated into VESA's DisplayPort 1.2a standard.

gsync-logo.jpg

We do not currently have an image of the monitor

4K could be where we really start seeing benefits for G-Sync. At that resolution, it is very difficult to get a system, regardless of how many GPUs are inside it, which can play the most modern of games without dipping below 60 FPS. Once you miss your 16.67 millisecond window, your game starts hitching between images living 33.33ms and 16.67ms, when each frame is supposed to be presented at a constant rate.

As for pricing and availability: Q2 (early May to end of July). That's all we know.
