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.

Why would you want a USB 3.0 4K display adapter you might ask? Perhaps you have an ultrabook with limited display outputs that do not output in 4K resolution but somehow you managed to get your hands on a 4K display for work or leisure and have a need for the full resolution. Club 3D now has a family of USB adapters for you, the CSV-2302 USB 3.0 to DisplayPort 4K, CSV-2301 USB 3.0 to DisplayPort 1600p and the CSV-2300D USB 3.0 to DVI-I graphics adapters. This is the first implementation of the DisplayLink DL-5500 chipset and it does indeed support 10bit colour if your display can handle it.
The MSRP for this device when it starts to ship in about 2 weeks will be ~$142.
Club 3D officially launches the next generation of USB 3.0 Graphics adapters capable of outputting high resolutions to DVI-I (2048x 1152p), DisplayPort (2560x 1600p) and the world’s first USB 3.0 to DisplayPort Graphics (CSV-2302) adapter which supports 4K or Ultra High Definition resolution at 3840x 2160p.
The Universal Serial Bus (USB) Port of a desktop computer or notebook is multifunctional and can be used to connect a large variety of (storage) devices, keyboards, mice and and other peripherals like monitors. Back in 2011, Club 3D introduced its first SenseVision USB Graphics adapters. These small external graphics adapters can be used to connect a DVI or HDMI monitor to the USB 2.0 output of a Desktop Computer or Notebook and create a multi screen setup.
The SenseVision USB adapters proved to be very successful across the globe! Not only with travelers but also in (semi) professional environments where more monitors mean more productivity.
The new Club 3D USB 3.0 Graphics adapters are fully ‘Plug and Display’ certified and the USB 3.0 to 4K Graphics Adapter (CSV-2302) is the very first to use the brand new DisplayLink DL-5500 chipset enabling 4K Ultra High Definition output to DisplayPort enabled 4K monitors at 30Hz. The Club 3D USB 3.0 to 4K Graphics Adapter (CSV-2302) is the first device available worldwide with the revolutionary new DisplayLink SoC implemented.
This Graphics adapter uses little resources of your system so it won’t affect performance ensuring at the same time a great image quality. It’s the ideal solution for anyone wanting to expand desktop space in order to use multiple programs simultaneously.
- 3840x2160 output at 30Hz
- Backwards compatible with QHD and HD monitors
- DP 1.2 interface (DisplayPort)

Tagged: oculus vr, oculus rift, Oculus
The popular VR headset development kit, Oculus Rift DK2, is no longer available for order in China. The reason, according to their subreddit, is due to "extreme reseller purchases". In other words, because too many were purchased with the intention of selling them at a markup. They, then, ask enthusiasts to wait for the consumer version. These are for developers to develop.
Reselling product happens frequently. You see it at big sales, when a retailer sells product near (or under) cost to lure people into their stores. Unless they have a quantity-per-purchase limit, that is enforced, you will see the occasional person buying obscene amounts. Some will even tell the cashier that they intend on reselling it elsewhere.
Oculus is "looking into alternative ways to make sure that our development kits are getting into legitimate developer hands in China". Also, they claim to have not canceled all orders in China., because, "that would be messed up".
Yes, Oculus, that would be.
The Oculus Rift DK2 is still available in the other regions.

An interesting press release found its way into my inbox just now that announces a new competitor to the world of 4K monitors. Seiki, made famous recently for its line of incredibly low cost 4K TVs that really started the 4K trend for consumers and PC gamers, is building a set of three professional series 4K monitors for release early next year with some damned impressive specifications.
Though you can find the 50-in Seiki SE50UY04 for just $799 on Amazon and the 39-in SE39UY04 for only $469, these are televisions with somewhat limited 30 Hz refresh rates. The new products that Seiki is showing for the first time at CE Week Exhibits and Conferences in New York City do not have any of these limitations though and instead boast one of the most complete list of specifications I have seen on a monitor.
Seiki SE39UY04 4K Television
Seiki will introduce three different sizes including a 28-in (28U4SEP-G02), 32-in (32U4SEP-G02) and 40-in (40U4SEP-G02) offering with the following specs:
- Vertical Alignment (VA) LED panel technology with 3,840 by 2,160 4K Ultra HD
- 12-bit color processing and 14-bit gamma mode
- HDMI 2.0, DisplayPort 1.3, MHL 3.0, DVI and VGA standards display connections
- Picture-by-picture (x4) and daisy chain mode
- USB 3.0 hub (1 upstream and 2 downstream)
- VESA-compliant adjustable monitor stand with quick release
I am still waiting for confirmation on the panel
type quality (more like TN or more like IPS, etc.) but the list of specifications here offers a glimpse of what to expect. (Vetical Aligned panels should be pretty damned good.) 12-bit color and 14-bit gamma indicate that this display will be built for the professional and creative designer at heart. Support for upcoming standards like HDMI 2.0 and Displayport 1.3 should tell you that the monitors won't be shipping for a while (Q1 2015 I'm told) but when you have them they will be able to push 4K at 60 Hz without issue.
The quad PiP mode could be really cool if it works as I suspect - four different HDMI inputs allow for four unique unscaled images on the panel at the same time. This could be great for multi-display uses where consumers can utilize a set of four 20-in (effective) 1080p panels without a bezel. We are already drooling over the possibilities of that here for our test setups...
So while I am excited about the prospect of these monitors, we don't yet know the pricing. If these are high quality IPS displays you can expect them to be quite expensive. But Seiki is known for building great displays at a low cost, so perhaps the company will be able to do so once again and surprise us all in time for CES next year.

A couple of really nice Amazon picks hit my email box today and I thought they were worth posting for our readers as well.
First, and clearly the most exciting: the 1TB version of the Samsung 840 EVO SSD is now selling for just $399. That comes in at $0.399/GB, which is actually better than the cost per GB of the Crucial MX100 that launched this month. If you haven't picked up an SSD that is big enough to hold all your games, this is the perfect opportunity!
Also, after our review went up at the end of May, the 4K ASUS PB287Q 28-in monitor is finally up for sale on Amazon for $649 with a shipping date of July 1st. If you think you might be interested in the universe of gaming at 4K, now is a great time to jump in.
Thanks for supporting PC Perspective!

A couple of years ago, you might remember my review of the Wacom Cintiq 22HD. It was not a review unit. I was originally saving for the Cintiq 24HD until the 22HD and the 24HD Touch were announced. At that point, I was making decision whether to upgrade to the 24HD with a touchscreen for Windows 8 development, or save some money and get the 22HD. If you have read my many editorials on Windows Store certification requirements, you might guess that, at least I believe, I made the right decision.
Image Credit: Hack a Day
This purchase was actually the second graphics tablet that I owned. Years earlier, I purchased an Adesso CyberTablet 12000 but had problems with drawing in one location and seeing the results in another. I, then, transitioned to scanning pencil-and-paper and inking/filling them with a mouse. It was at that point that I took a gamble on a Wacom Cintiq.
Why am I telling this story? Wacom Cintiqs are based on the same technology as their Intuos tablets, even down to pen compatibility, with a display built in. Well, at Hack a Day, one of their clever readers decided to make their own Cintiq out of what appears to be a Wacom Intuos3 A5. Basically, he fit a replacement 9.7-inch, 2048x1536 display, designed for Retina iPads and similar tablets, behind the touch sensor. It apparently worked without much fuss.
You can find Wacom Intuos3 6 x 8-inch pen tablets for about 120-150$ used. You can also find a 9.7-inch 2048x1536 panel and the other necessary hardware for about $70. While it is not an exact replacement for a Wacom Cintiq, it is the best you will do for under $250 (or even under $900).

We interrupt your Computex news stream with a product that is currently for sale, the Philips Brilliance 239C4QHWAB with Miracast support. The screen itself is something we have seen before, a 1080p 23" IPS display with HDMI and VGA inputs on the base along with an audio and microphone input. Now those specs will not impress a gamer looking for a 4k display but for someone with an Android device that wants to stream 1080p video via Miracast thanks to the in built support the resolution and connections are perfect. Check out how well it handles Miracast at Bjorn3D.
"With the rise of mobile devices the need to be able to hook them up to a screen has increased. While both Apple TV and to some extend Google Chromecast offers ways to mirror the screen on supported devices or at least stream some content they both requier extra hardware. There is however another solution: Miracast."

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.
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.
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."
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.
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.

Philips has announced what they are calling the worlds first "virtually seamless" two-in-one monitor.
The Philips Two-in-One monitor proudly showing Computex gold (though not as prestigious as the PC Perspective gold award, of course...)
The 19DP6QJNS (love those model names, don't you?) is comprised of two separate 19" IPS displays on a single mount, and the ultra-thin 3.5mm bezels allow for the that "virtual" seamlessness.
The announcement does not include screen resolution, and from the images the screens don't appear at least to be the usual 16:9 aspect ratio. Even without all of the details there is a clear advantage to a design with a reduced footprint. It's just a more, well, seemless (there's that word again) dual-monitor setup. Each display has its own video inputs, though they are different. The first display has a DisplayPort and VGA input, and the second has a VGA input and MHL-enabled HDMI input. The monitors can tilt up to 22 degrees, and each screen also has a pair of USB ports.
So about the resolution... Philips states that this new product is "ideal for designers using 3D graphics or requiring extremely detailed information for CAD-CAM solutions," so one wouldn't be faulted for assuming a higher resolution panel here, but we will have to see. This is certainly a niche product, but anyone who has grown accustomed to a dual monitor setup will probably tell you they are more productive (and would never willingly go back). If this is reasonably priced, two IPS screens on a single stand would be a really attractive proposition.
The Philips 19DP6QJNS will be available fall 2014, and no pricing information yet.

Remember DockPort? The three in one connection we have discussed in the past? The Thunderbolt-ish connection for devices with DisplayPort which allows transmission of audio and video plus USB data and power all on one connector. It's here! (even if the devices aren't quite common yet)
NEWARK, CA (3 June 2014) The Video Electronics Standards Association (VESA) today announced the release of the DockPort standard. Developed by several VESA member companies, DockPort is an optional extension of the DisplayPort standard that will allow USB 3.1 data and DC power for battery charging to be carried over a single DisplayPort connector and cable that also carries high-resolution audio/video (A/V) data.
This new extension of the DisplayPort standard is fully backward compatible with all existing DisplayPort devices. When a DockPort-enabled DisplayPort source such as a computer or tablet is connected with a DockPort-enabled DisplayPort sink such as a display monitor or docking station A/V plus USB data and power will be transferred over a common cable through a single connector. If either the source or sink device is not a DockPort-enabled, then source and sink will recognize only the DisplayPort A/V data stream.
As computing platforms become increasingly mobile, it becomes necessary to reduce the number of external connectors, explained Steve Belt, Corporate Vice President - Strategic Alliances & Solutions Enablement AMD, a VESA member company. With DockPort, VESA has developed a technology standard that enhances elegant docking designs, reduces mobile form factors, and enriches the user experience with streamlined, one-cable access to a wide range of external displays, peripherals and storage.
DockPort is the first royalty-free industry standard that combines these three essential interface functions into a single connector. VESA first revealed its intention to develop this standard at the 2014 International Consumer Electrics Show. It anticipates that several vendors will demonstrate DockPort-enabled DisplayPort systems at Computex Taiwan, which begins today.
Until today, most mobile computing platforms required three separate interfaces to support power charging, data transmission and external video, said Chris Griffith, Business Development Manager for Consumer and Computing Interface at Texas Instruments, a VESA member company. With DockPort, VESA has elegantly merged this ungainly tangle of wires into a single, sleek connector, combining power charging with the industrys most popular data transportUSBand the industrys highest-speed A/V transportDisplayPort. DockPort can reduce system implementation cost as designers can reduce external connectors and simplify docking implementations.
VESA is developing a compliance test protocol to certify systems that meet the DockPort standard. Systems that satisfy this test protocol will be permitted to display VESAs new DockPort logo on their packaging as a guide for consumers seeking this capability.
The new DockPort standard demonstrates the enormous adaptability of the DisplayPort standard, according to VESA Board Chair Alan Kobayashi, Fellow & Executive R&D Management for DisplayPort Group at MegaChips Technology America. On the one hand, DisplayPort is a flexible A/V transport protocol that easily coexists with other protocols, like USBit plays nicely with others. On the other hand, DisplayPort is also a robust and proven connector design whose electro-mechanical properties can accommodate data and power over a common passive copper cable and interface.
