It is official, DisplayPort 1.3 has finished VESA approval and should be hitting the streets in the near future. Freesync support came with 1.2a which is why it was not mentioned, however DockPort has been enhanced with the higher 8.1 Gbps link rate for each of the four lanes present which means you can support a 4k monitor using two of those lanes, leaving the other two available for USB, audio or even power.
This also means that 4k and even 5k monitors can function over a single DisplayPort 1.3 cable without any compression and with the use of VESA's Coordinated Video Timing you can have a pair of 4k monitors function in multi-monitor mode ... assuming you have the graphical horsepower to run 7680 x 2160. It is rather impressive to see this jump to 32.4 Gbps combined link rate that can deliver 25.92 Gbps of uncompressed video data.
Newark, CA (15 September 2014) The Video Electronics Standards Association (VESA) announced the release of the DisplayPort 1.3 audio / video (A/V) standard. An update to the widely used DisplayPort 1.2a standard, this latest version increases the maximum link bandwidth to 32.4 Gbps, with each of four lanes running at a link rate of 8.1 Gbps/lane a 50% increase from the previous version of the DisplayPort standard. Allowing for transport overhead, DisplayPort's 32.4 Gbps combined link rate delivers 25.92 Gbps of uncompressed video data.
The increased bandwidth enables higher resolution monitors, including recently announced 5K monitors (with pixel resolutions of 5120 x 2880) using a single DisplayPort cable without the use of compression. It will also enable higher resolutions when driving multiple monitors through a single connection using DisplayPort's Multi-Stream feature, such as the use of two 4K UHD monitors, each with a pixel resolution of 3840 x 2160, when using VESA Coordinated Video Timing.
DisplayPort 1.3 continues to support video conversion to VGA, DVI and HDMI. DisplayPort 1.3 adds support for HDCP 2.2 and HDMI 2.0 with CEC (Consumer Electronics Control), which enhances DisplayPort's utility for television applications, including 4K video with copy protection. The new standard adds support for the 4:2:0 pixel structure, a video format commonly used on consumer digital television interfaces, which enables support for future 8K x 4K displays.
DisplayPort 1.3 also enhances DisplayPort's value for multi-function interfaces that combine data transport, A/V transport and other capabilities on a single cable. It further refines protocols that enable DisplayPort to share a single cable with other data types. With its higher 8.1 Gbps per-lane link rate, DisplayPort 1.3 can support a single UHD monitor with 60Hz refresh and 24-bit color over two lanes, while assigning the remaining two lanes to increase capacity for alternate data types, such as SuperSpeed USB data, as allowed in DockPort. DisplayPort is the A/V transport standard used by DockPort, Thunderbolt and other wired and wireless multi-function interface standards.
While becoming a mainstream video standard, DisplayPort continues to be at the cutting edge of A/V transport, said VESA Board of Directors Chair Alan Kobayashi, Fellow & Executive R&D Management for DisplayPort Group at MegaChips Technology America. These new enhancements to DisplayPort will facilitate both higher resolution displays, as well as easier integration of DisplayPort into multi-protocol data transports, which will satisfy consumer's desire for simplicity and ease-of-use.
The DisplayPort standard is offered to VESA members without any license fee. For more information about DisplayPort, please visit http://www.displayport.org or connect with us on YouTube.

That's right, Dell is releasing the Dell UltraSharp 27 Ultra HD 5K Monitor with a resolution of 5120 x 2880 for a mere $2500 just in time for Christmas. That is just under 6.5 million more pixels than 4k which is an impressive jump and should look very interesting on a 27" display!
While we may not have TV content to justify this resolution gamers with extreme GPUs should be able to take advantage of it as soon as it is released. You will probably be able to turn your anti-aliasing settings down with pixels that small. It will also have 16W integrated Harmon Kardon speakers and quite likely a few USB ports. Surround setups are going to need every PCIe lane you can toss at it though, good thing those 295X2's are on sale right now! They've also added some information about their 4K displays here.

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.
NVIDIA Live Stream with Tom Petersen
9am PT / 12pm ET - August 22nd
The topic list is going to include (but not limited to):
- ASUS PG278Q G-Sync monitor
- G-Sync availability and pricing
- G-Sync Surround setup, use and requirements
- Technical issues surrounding G-Sync: latency, buffers, etc.
- Comparisons of G-Sync to Adaptive Sync
- SHIELD Tablet game play
But we want your questions! Do you have burning issues that you think need to be addressed by Tom and the NVIDIA team about G-Sync, FreeSync, GameWorks, Tegra, tablets, GPUs and more? Nothing is off limits here, though obviously Tom may be cagey on future announcements. Please use the comments section on this news post below (registration not required) to ask your questions and we can organize them before the event tomorrow. We MIGHT even be able to come up with a couple of prizes to giveaway for live viewers as well...
See you tomorrow!!

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.

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.”
Here are some more Display articles from around the web:

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.

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.

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.
