VESA Releases DisplayPort 1.3 Standard

Kaapstad · 15 Sep 2014 at 15:07

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.

This is good news for anyone thinking about 4K, now what we need is some cards that use the new standard.

Finally, only a few months late.

Adaptive Sync still optional then?

sweet! Sell me a cable lol

If upcoming monitors launch with 1.3 DP with Freesync on 1.3.

Would we need GPU's capable of 1.3?

Probably not as DP is backwards compatible and freesync is a revision of 1.2 anyway (just like gsync is).

Display Port is B/C, so you wouldn't need a new GPU just to use a 1.3 monitor.
As far as I'm aware, adaptive sync was added in optionally into 1.2A?

But still, we need actual solid information if a 1.3 DP monitor with Adaptive Sync would work on a current AMD GPU such as the R9 290 using adaptive sync.

In my head I can see it going either way, we'd need confirmation from AMD.

That means you can connect a 1.3 screen to a 1.2 GPU and it will work at 1.2 speeds though right? You won't be able to get 1.3 performance out of a 1.2 GPU simply by connecting to a 1.3 screen?

Indeed.

Hence the question about adaptive sync, as surely it'd be a 1.3 feature? (Ignoring it's in the 1.2A as optional, as the monitors will be 1.3 going in, maybe we'll see the first few freesync's trickle in with 1.2A, but there's also a chance we don't)

That's how I see it in my head, needs confirmation.

Robert was aked if DP 1.2A (Free-Sync) GPU's would work with DP 1.3 Displays in his Q&A Free-Sync thread, the awnser is yes.

Does is mention free sync on the 1.3 displays? As the question "Would 1.2A GPU's work on 1.3 DP's" is a completely different question to mine.

Your right it doesn't, one would asume that if DP 1.2A has Free-Sync then so would DP 1.3.

The features list would be "added all of the above" not "this is the full features list"

It's AMD, any assumption I make is pessimistic (And generally closer to the truth). Monitor side, 1.2A is optional for adaptive sync. If it's a 1.3 monitor that has it as a feature, I really wouldn't be surprised to see my 1.2 GPU not work with adaptive sync on it.

Like I say, requires a properly worded question.

This was asked in the QA and we received an answer along the lines of no idea.

No i asked again and got yes ^^^^^

Its VESA not AMD, but i see your point, you could always ask Robert to clarify.

DisplayPort 1.3 supports 5K at 32.4Gbps

4K at 120Hz possible

VESA has announced DisplayPort 1.3 and the new standard is capable of powering high-resolution displays at higher refresh rates than ever.

DisplayPort 1.3 boasts 32.4Gbps of bandwidth, up from 21.6Gbps on DisplayPort 1.2, which was announced in 2009.

Thanks to the added bandwidth, the new standard can cope with 5K resolutions at 60Hz. We are not fans of the new “5K” designation used by the industry, but nevertheless this is quite an achievement. More importantly, DisplayPort 1.3 can drive 4K displays at 120Hz.

The standard also supports 8K wide resolutions (7680x2160) at 60Hz. Who would say no to a few rounds of, well anything on a wide 8K display? Support for HDCP 2.2 and HDMI 2.0 CEC is also on board.

4K and 120htz wicked.

Shame there are no monitors that support it.

VincentHanna · 16 Sep 2014 at 09:39

What I don't understand is they are saying that DP 1.3 will now support HDMI 2.0.

But DP 1.2 already has more bandwidth than HDMI 2.0, so I don't see why you couldn't use a DP 1.2 port -> HDMI, as long as somebody releases an active adapter.

andybird123 · 16 Sep 2014 at 11:22

Yes, IF someone releases an active adapter, with dp 1.3 you would just need a DP to Hdmi cable, not a more expensive active adapter

VincentHanna · 16 Sep 2014 at 11:35

I see.

So 1.3 -> HDMI 2.0 is a simple passive adapter.

Makes sense.

G-SYNC is proprietary, it's not a revision of anything and is certainly not a VESA standard :confused:

Asa · 28 Sep 2014 at 12:48

Bit of an old thread, but I just had a a look at the displayport FAQ and it states that some 1.2a sources will be updatable to the new standard by firmware.

My fingers are firmly crossed for the 290 series, perhaps my PC and my 4K TV can resolve their differences!
