AMD might have originally thought that dynamic refresh rates were not worth adding to their machines but they did develop FreeSync quite a while ago and now that G-Sync is available they've changed their minds. Even better for the consumer is the way that they went about releasing it; not as proprietary hardware which is only compatible with certain monitors but as an update to the DisplayPort standard which does not require any extra hardware. We do still have a while to wait before these monitors hit the shelves, the display scaler and control chips manufactures will have to incorporate the new standard into their designs but once they do they should be functional on both NVIDIA and AMD as long as you are connecting with DisplayPort. Read more about the process on The Tech Report.
Also, you can read the official VESA press release.
"PC gaming animation may soon become more fluid than ever, thanks to a development just announced by the folks at the VESA display standards organization. VESA has officially added a feature called Adaptive Sync to the DisplayPort 1.2a specification, which means that a G-Sync-style adaptive refresh mechanism could be built into nearly every new desktop monitor in the coming months and years."

3840x2160 for Cheap!!
It has been just over a year ago when we first got our hands on a 4K display. At the time, we were using a 50-in Seiki 3840x2160 HDTV that ran at a 30 Hz refresh rate and was disappointing in terms of its gaming experience, but impressive in image quality and price ($1500 at the time). Of course, we had to benchmark graphics cards at 4K resolutions and the results proved what we expected - you are going to need some impressive hardware to run at 4K with acceptable frame rates.
Since that story was published, we saw progress in the world of 4K displays with the ASUS PQ321Q, a 4K monitor (not a TV) that was built to handle 60 Hz refresh rates. The problem, of course, was the requirement for a multi-stream connection that essentially pushes two distinct streams over a single DisplayPort cable to the monitor, each at 1920x2160. While in theory that wasn't a problem, we saw a lot configuration and installation headaches as we worked through the growing pains of drivers and firmware. Also, it was priced at $3200 when we first reviewed it, though that number has fallen to $2400 recently.
Today we are looking at the Samsung U28D590D, the first 4K panel we have seen that supports a 60 Hz refresh rate with a single stream (single tile) implementation. That means that not only do you get the better experiences associated with a 60 Hz refresh rate over a 30 Hz, you also gain a much more simple and compatible installation and setup. No tricky driver issues to be found here! If you have a DisplayPort 1.2-capable graphics card, it's just plug and play.
The Samsung U28D590D uses a 28-in TN panel, which is obviously of a lower quality in terms of colors and viewing angles than the IGZO screen used on the ASUS PQ321Q, but it's not as bad as you might expect based on previous TN panel implementations. We'll talk a bit more about that below. The best part of course is the price - you can find the Samsung 4K panel for as low as $690!

If you are going to use Windows 8 as your OS you will find it is a better overall experience to use if you have a touchscreen. With mobile devices that is not a problem but for the most part desktop systems do not tend to sport a touchscreen. Enter the Philips 231C5 SmoothTouch a 23" IPS 1080p display with a built in webcam and microphone as well as multi-touch capability of course. The array of inputs are sufficient, two HDMI ports – one with MHL capabilities, DisplayPort, VGA, two USB 3.0 ports and stereo audio. Before you dismiss this display completely you should check out eTechnix full review.
"When Microsoft announced the imminent launch of Windows 8, one of the revolutionary aspects of the new operating system was its more streamlined integration into touch screen devices. Since that time we have seen touch screen capable notebooks and Ultrabooks swarm the market and the era of the touch screen computer has changed the way that many of us have interacted with our systems."

According to French website, hardware.fr, the VESA standards body has accepted AMD's proposal for FreeSync into an extension of the DisplayPort 1.2a standard. FreeSync is the standards-based answer to NVIDIA's G-Sync, a process for allowing the monitor to time itself according to its driving GPU. At CES 2014, AMD claimed that the technology was already in development to be used for mobile devices to save power (less frequent monitor refreshes).
By presenting image to the user only when the work is complete, you can avoid "tearing" and latency. The tearing will be eliminated because the graphics card does not change the image being drawn by the monitor as it is trying to display it. The latency is eliminated because it does not need to wait until the monitor is ready (up to one-over-the maximum refresh rate of the monitor). It should also save power by reducing its refresh rate on slower scenes, such as an idle desktop, but that is less of a concern when you are plugged into a wall.
What does this mean? Nothing yet, really, except that a gigantic standards body seems to approve.
Ever since CES we have been expecting an onslaught of 4K monitors to make their way to the market. Today Amazon.com listed the Samsung U28D590D for pre-order for the price of just $699. This is a 28-in display with a 3840x2160 resolution and support for 60 Hz refresh rates courtesy of the DisplayPort 1.2 connection.
That's a hell of a deal for a 4K monitor, especially one capable of 60 Hz (likely through MST)! Worth noting is that the monitor is a TN panel so picture quality won't be as good as the IPS options still selling for over $2500, like the ASUS PQ321Q we reviewed previously.
The panel has a pair of HDMI inputs but both are listed as only supporting 30 Hz 3840x2160 resolutions without any mention of using them both simultaneously.
You can find the full specifications list on Samsung's website, and we are working to get a sample in for testing in the next two weeks!

Tagged: VR, valve, Oculus, facebook
Today, Oculus VR issued a statement which claims that Michael Abrash has joined their ranks as Chief Scientist. Abrash was hired by Valve in 2011 where he led, and apparently came up with the idea for, their wearable computing initiatives. For a time, he and Jeri Ellsworth were conducting similar projects until she, and many others, were forced out of the company for undisclosed reasons (she was allowed to take her project with her which ultimately became CastAR). While I have yet to see an official announcement claim that Abrash has left Valve, I have serious doubts that he would be employed in both places for any reasonable period of time. With both gone, I wonder about Valve's wearable initaitive going forward.
Abrash at Steam Dev Days
This press statement comes just three days after Facebook announced "definitive" plans to acquire Oculus VR for an equivalent of $2 billion USD (it is twice the company Instragram was). Apparently, the financial stability of Facebook (... deep breath before continuing...) was the catalyst for this decision. VR research is expensive. Abrash is now comfortable working with them, gleefully expending R&D funds, advancing the project without sinking the ship.
And then there's Valve.
On last night's This Week in Computer Hardware (#260), Patrick Norton and I were discussing the Oculus VR acquisition. He claimed that he had serious doubts about whether Valve ever intended to ship a product. So far, the only product available that uses Valve's research is the Oculus Rift DK2. Honestly, while I have not really thought about it until now, it would not be surprising for Valve to contribute to the PC platform itself.
And, hey, at least someone is not afraid of Facebook's ownership.

Last month, we published a news piece stating that Oculus Rift production has been suspended as "certain components" were unavailable. At the time, the company said they are looking for alternate suppliers but do not know how long that will take. The speculation was that the company was simply readying a new version and did not want to cannibalize their sales.
This week, they announced a new version which is available for pre-order and expected to ship in July.
DK2, as it is called, integrates a pair of 960x1080 OLED displays (correction, March 22nd @ 3:15pm: It is technically a single 1080p display that is divided per eye) for higher resolution and lower persistence. Citing Valve's VR research, they claim that the low persistence will reduce motion blur as your eye blends neighboring frames together. In this design, it flickers the image for a short period before going black, and does this at a high enough rate keep your eye fed with light. The higher resolution also prevents the "screen door effect" complained about by the first release. Like their "Crystal Cove" prototype, it also uses an external camera to reduce latency in detecting your movement. All of these should combine to less motion sickness.
I would expect that VR has a long road ahead of it before it becomes a commercial product for the general population, though. There are many legitimate concerns about leaving your users trapped in a sensory deprivation apparatus when Kinect could not even go a couple of days without someone pretending to play volleyball and wrecking their TV with ceiling fan fragments. Still, this company seems to be doing it intelligently: keep afloat on developers and lead users as you work through your prototypes. It is cool, even if it will get significantly better, and people will support its research while getting the best at the time.
DK2 is available for pre-order for $350 and is expected to ship in July.

NVIDIA's new G-Sync variable refresh rate technology is slowly being rolled out to consumers in the form of new monitors and DIY upgrade kits that can be used to add G-Sync functionality to existing displays. The first G-Sync capable monitor to support the DIY upgrade kit path is the ASUS VG248QE which is a 24" 1080p 144Hz TN panel. The monitor itself costs around $270 and the you can now purchase a G-Sync DIY upgrade kit from NVIDIA for $199.
The upgrade kit comes with a replacement controller board, power supply, HDMI cable, plastic spudger, IO shields, and installation instructions. Users will need to take apart the VG248QE monitor, remove the old PCBs and install the G-Sync board in its place. According to NVIDIA the entire process takes about 30 minutes though if this is your first time digging into monitor internals it will likely take closer to an hour to install.
The NVIDIA G-Sync DIY kit below the ASUS VG248QE monitor.
For help with installation, NVIDIA has posted a video of the installation process on YouTube. If you find text and photos easier, you can follow the installation guides written up for PC Perspective by Allyn Malventano and reader Levi Kendall. Both DIY kit reviews stated that the process, while a bit involved, was possible for most gamers to perform with a bit of guidance.
You can order the DIY upgrade kit yourself from this NVIDIA page.
Alternatively, ASUS is also releasing an updated version of the VG248QE monitor with the G-Sync board pre-installed in the first half of this year. This updated G-Sync monitor will have an MSRP of $399.
With the G-Sync kit at $199, will you be going the DIY path or waiting for a new monitor with the technology pre-installed?

Just before CES Allyn showed you the process of modifying the ASUS VG248QE to support NVIDIA G-Sync variable refresh rate technology. It wasn't the easiest mod we have ever done but even users without a lot of skill will be able to accomplish it.
But at the NVIDIA booth at CES this year the company was truly showing off G-Sync technology to its fullest capability. By taking the 3840x2160 ASUS PQ321Q monitor and modifying it with the same G-Sync module technology we were able to see variable refresh rate support in 4K glory.
Obviously you can't see much from the photo above about the smoothness of the animation, but I can assure you that in person this looks incredible. In fact, 4K might be the perfect resolution for G-Sync to shine as running games at that high of a resolution will definitely bring your system to its knees, dipping below that magical 60 Hz / FPS rate. But when it does with this modified panel, you'll still get smooth game play and a a tear-free visual experience.
The mod is actually using the same DIY kit that Allyn used in his story though it likely has a firmware update for compatibility. Even with the interesting debate from AMD about the support for VRR in the upcoming DisplayPort 1.3 standard, it's impossible to not see the ASUS PQ321Q in 4K with G-Sync and instantly fall in love with PCs again.
Sorry - there are no plans to offer this upgrade kit for ASUS PQ321Q owners!
