Still wondering about adaptive refresh and why it matters to more than the 144Hz crowd?

The Tech Report published a video of Freesync in action using a camera which records at 240 fps.  The subject material is running at less than the 60Hz that most of our monitors use which means that you can actually see what it does for you.  Watching the video at 60Hz you can see the tearing on the blades of the windmill as the actual frame rate of the render is 44 - 45Hz while when Freesync is active the matched frequencies do not cause any tearing.  The demonstration shows how Freesync can benefit lower end systems that are not going to push a 144Hz monitor to the limits, if you can only manage 40-50 fps in a game Freesync is going to make it much easier on your eyes.  You can catch our latest coverage of Freesync here.

"We've been hearing about FreeSync, AMD's answer to Nvidia's G-Sync variable refresh display tech, for just over a year now. This week at CES, we finally got a chance to see FreeSync in action, and we used that opportunity to shoot some enlightening 240-FPS footage. We were able to find out some new specifics from AMD, as well."

CES 2015: ASUS MG279Q 27-in 2560x1440 IPS 120 Hz Variable Refresh Monitor

We have talked about G-Sync for what seems like years now and we got our first hands-on with AMD's FreeSync monitors earlier this week at CES, but the new ASUS MG279Q is in an interesting place: it is the first display that publicly supports Adaptive Sync and DP 1.2a+ but does not have an affiliation with either branded variable refresh rate technology. As it turns out though, that isn't bad news.

mg279q-2.jpg

First, let's talk about the hardware. The screen is a 27-in 2560x1440 display with IPS panel technology and a maximum refresh rate of 120 Hz. High refresh rate IPS monitors are brand new and we are glad to see that ASUS is bringing one to the market so we can finally combine great color, great viewing angles and great refresh rates. The monitor supports DP 1.2a+ and Adaptive Sync which leads us too...

mg279q-q.jpg

...the fact that this monitor will work with AMD Radeon graphics cards and operate at a variable refresh rate. After talking with AMD's Robert Hallock at the show, he confirmed that AMD will not have a whitelist/blacklist policy for FreeSync displays and that as long as a monitor adheres to the standards of DP 1.2a+ then they will operate in the variable refresh rate window as defined by the display's EDID.

So, as described by the ASUS reps on hand, this panel will have a minimum refresh of around 40 Hz and a maximum of 120 Hz, leaving a sizeable window for variable refresh to work it's magic.

Even better? The price! ASUS said this panel will ship in late Q1 of this year for just $599!

CES 2015: AMD Talks Technical about FreeSync Monitors

Subject: Graphics Cards, Displays, Shows and Expos | January 7, 2015 - 03:11 AM |
Tagged: video, radeon, monitor, g-sync, freesync, ces 2015, CES, amd

It finally happened - later than I had expected - we got to get hands on with nearly-ready FreeSync monitors! That's right, AMD's alternative to G-Sync will bring variable refresh gaming technology to Radeon gamers later this quarter and AMD had the monitors on hand to prove it. On display was an LG 34UM67 running at 2560x1080 on IPS technology, a Samsung UE590 with a 4K resolution and AHVA panel and BenQ XL2730Z 2560x1440 TN screen.

free-1.jpg

The three monitors sampled at the AMD booth showcase the wide array of units that will be available this year using FreeSync, possibly even in this quarter. The LG 34UM67 uses the 21:9 aspect ratio that is growing in popularity, along with solid IPS panel technology and 60 Hz top frequency. However, there is a new specification to be concerned with on FreeSync as well: minimum frequency. This is the refresh rate that monitor needs to maintain to avoid artifacting and flickering that would be visible to the end user. For the LG monitor it was 40 Hz.

free-3.jpg

What happens below that limit and above it differs from what NVIDIA has decided to do. For FreeSync (and the Adaptive Sync standard as a whole), when a game renders at a frame rate above or below this VRR window, the V-Sync setting is enforced. That means on a 60 Hz panel, if your game runs at 70 FPS, then you will have the option to enable or disable V-Sync; you can either force a 60 FPS top limit or allow 70 FPS with screen tearing. If your game runs under the 40 Hz bottom limit, say at 30 FPS, you get the same option: V-Sync on or V-Sync off. With it off, you would get tearing but optimal input/display latency but with it off you would reintroduce frame judder when you cross between V-Sync steps.

There are potential pitfalls to this solution though; what happens when you cross into that top or bottom region can cause issues depending on the specific implementation. We'll be researching this very soon.

free-3.jpg

Notice this screen shows FreeSync Enabled and V-Sync Disabled, and we see a tear.

FreeSync monitors have the benefit of using industry standard scalers and that means they won't be limited to a single DisplayPort input. Expect to see a range of inputs including HDMI and DVI though the VRR technology will only work on DP.

We have much more to learn and much more to experience with FreeSync but we are eager to get one in the office for testing. I know, I know, we say that quite often it seems.

As we learn more about these individual FreeSync-enabled models we will provide updates, and AMD has stated that there will be models shipping this month.

The full PR announcement from AMD appears below:


AMD today announced the expansion of the FreeSync ecosystem as technology partners including BenQ, LG Electronics, Nixeus, Samsung, and Viewsonic showcased their upcoming commercially available FreeSync-enabled displays at the 2015 International CES. The unveiling of new FreeSync-enabled displays demonstrates the industry's commitment to open standards-based technology that enables improved gaming by synchronizing dynamic refresh rates of the displays to the frame rate of AMD Radeon™ R-Series graphics cards and current generation APUs. The result greatly reduces input latency and helps reduce or eliminate visual defects during gaming and video playback. The new displays range in size between 24" to 34", supporting refresh rates of 30 to 144 Hz, and resolutions of 1080p up to Ultra HD, offering a variety of options for every gamer's needs and at virtually every price point.

"The broad adoption of FreeSync technology from our partners shows how the industry strongly values the same open ecosystem and quality that AMD strives for," said Roy Taylor, corporate vice president, ISV/IHV Partner Group, AMD. "Gamers who use FreeSync technology with AMD Radeon™ R-Series graphics and AMD latest generation of APUs can rest assured that they're enjoying the best possible experience."

Monitors from BenQ, LG Electronics, Nixeus, and Samsung are on display at AMD's booth, San Polo rooms 3402 - 3404 at The Venetian at CES Tech West. Displays are expected to be available in market starting this month with additional models set to launch in early 2015.

LG Announces 34UM67 UltraWide Gaming Monitor with AMD FreeSync

Subject: Displays | December 31, 2014 - 10:29 AM |
Tagged: LG, 34um67, ultrawide, 21:9, CES, ces 2015, freesync, adaptive sync

Let the variable refresh rate monitor battle begin! This week LG has announced a gaming-specific 21:9 aspect ratio monitor that features support for AMD's FreeSync variable refresh rate technology. LG joins Samsung as monitor vendors that have officially thrown in hats with the AMD-backed and VESA standard Adaptive Sync technology rather than NVIDIA's G-Sync (or maybe in addition to). 

The new 34UM67 is a flat, 34-in 21:9 aspect ratio display; a style that is becoming increasing popular among enthusiast and gamers as they offer expanding views in some games without the need to use multiple monitors in a Eyefinity or Surround configuration. LG has not announced the resolution yet but I assume that since they aren't bragging about it openly, that we are looking at a 2560x1080 screen rather than 3440x1440. Still, coupling that resolution with support for a variable refresh technology should provide an impressive gaming experience. 

lg34um67.jpg

Here is what the official press release has to say about the new LG 34UM67 being shown next week at CES:

LG's UltraWide Gaming Monitor (34UM67) is the company's first 21:9 monitor specifically developed for graphics-intensive gaming. AMD's FreeSync technology eliminates the screen tearing that occurs when the monitor and graphics card are out of sync. Furthermore FreeSync technology guarantees the smoothest and most seamless gaming experience, generating fluid motion without any loss of frame rate.

"AMD FreeSync technology is an innovative monitor technology, based on free and open industry standards, to eliminate the tearing and stuttering that has plagued PC gaming for 30 years," said Roy Taylor, corporate vice president of ISV/IHV Partner Group, AMD. "We are pleased that LG Electronics stands with us with truly exciting  AMD FreeSync-ready displays like the LG UltraWide Gaming Monitor."

The 34UM67 also has an exceptional UltraWide field of view (FOV), allowing gamers to gain the upper hand by revealing hidden spaces that were invisible on regular 16:9 monitors. The monitor's Black Stabilizer illuminates dark scenes and helps to clearly define the deep black areas where objects and enemies could be hidden. The Dynamic Action Sync mode minimizes input lag, enhancing users' real time gaming experience. Many popular games such as Battlefield 4, World of Warcraft and ArcheAge currently support 21:9 resolution with more games expected to support this resolution in the future.

Support for 21:9 resolutions is still spotty in most PC titles and can result in the same kind of FOV scaling issues we see with Eyefinity. More games are including direct support for these monitors and hopefully 2015 will see a focus on that with each game release. 

I still have a lot of questions about AMD's FreeSync technology and how it will stand up to the effectiveness of NVIDIA G-Sync, but I am eager to see it first hand. CES will provide the first opportunity for us but we will obviously need extended time with panels in our offices to make a final decision.

Samsung Announces First FreeSync UHD Monitors

Subject: Displays | November 20, 2014 - 10:50 AM |
Tagged: TN, Samsung, nvidia, monitor, ips, g-sync, freesync, amd

We have been teased for the past few months about when we would see the first implementations of AMD’s FreeSync technology, but now we finally have some concrete news about who will actually be producing these products.

Samsung has announced that they will be introducing the world’s first FreeSync enabled Ultra HD monitors.  The first models to include this feature will be the updated UD590 and the new UE850.  These will be introduced to the market in March of 2015.  The current UD590 monitor is a 28” unit with 3845x2160 resolution with up to 1 billion colors.  This looks to be one of those advanced TN panels that are selling from $500 to $900, depending on the model.

AMD had promised some hand’s on time for journalists by the end of this year, and shipping products in the first half of next year.  It seems that Samsung is the first to jump on the wagon.  We would imagine that others will be offering the technology.  In theory this technology offers many of the same benefits of NVIDIA’s G-SYNC, but it does not require the same level of hardware.  I can imagine that we will be seeing some interesting comparisons next year with shipping hardware and how Free-Sync stacks up to G-SYNC.

Joe Chan, Vice President of Samsung Electronics Southeast Asia Headquarters commented, “We are very pleased to adopt AMD FreeSync technology to our 2015 Samsung Electronics Visual Display division’s UHD monitor roadmap, which fully supports open standards.  With this technology, we believe users including gamers will be able to enjoy their videos and games to be played with smoother frame display without stuttering or tearing on their monitors.”
