The standard, which will serve as a primary interconnection between monitors and personal computers (PCs), was ratified only recently, which means that the first graphics cards and, perhaps, displays will need a special chip that transmits signals according to DisplayPort standards.

umm, nooby question, what is displayport? what does it do?

[VulgarHandle]

ok, like a usb connection :D

[[XC] leviathan18]

no like HDMI but for pc... no more vga or dvi now displayport

[RAMMAN]

so r600 and maybe g80 will require a new monitor to work?

[OmegaMerc]

Doubt they would be naive enough to make it a "new monitor only" option.

[eBoy0]

Yah probley adapters will be avaliable, just like analog > dvi.

Hopefully otherwise they will get kicked to the curb...

imsrue at first we'll see a dvi and display port interface on them

[Thorry]

AFAIK it's not really possible to simply adapt from analog to DVI, when the DVI standard was created they incorperated the analog VGA standard renaming it DVI-I.

The good old VGA pins are simply in different places on the DVI connector (the DVI-I pins) but the signal remains the same. That accounts for the succes of DVI.

There are lots of people out there with expensive DVI cables and a nice DVI setup but not knowing they are using DVI-I and thus in fact still using good old VGA.

If you want digital DVI you need DVI-D (not only on the graphic card, but also on the cable and offcourse the monitor).

With this displayport it will prolly be simular, leaving a simple way for DVI and VGA to connect 1:1 making cheap adapters possible.

[onewingedangel]

dvi-I contains both analogue and digital output pins, DVI-D only the digital ones, this means you can't use a vga adaptor on a dvi-d only output, but dvi-i outputs, used with a dvi-i cable into a dvi-i display will be fully digital, using the same signal as dvi-d. Its unlikely anyone running dvi-i is using the analogue signal without using an adptor to use a vga cable.

Heres a question though, why not just use HDMI?

[[XC] leviathan18]

because they are stupids and want something different for pc instead of leaving us alone with our DVI

[MaxxxRacer]

here is a question.. why not let DVI stay the standard.. I am quite happy with it... What is the problem?

[[XC] leviathan18]

HDCP and all that crap

[ahmad]

HDCP and all that crap

Thats only a small part of it. If you read carefully enough:

The DisplayPort is designed to enable a common interface approach across both internal and external display connections. Internal connections include display interfaces within a notebook PC or within an LCD display. External display connections include the interface between a source device such as a desktop PC, set-top box, DVD player or game console, and a display device such as a direct view flat panel or projection display for viewing video and graphics. The DisplayPort standard will also include an optional digital audio capability allowing streaming of high definition digital audio-video content over the interface, and provides performance scalability to enable the next generation of displays featuring higher color depths, refresh rates, and display resolutions.

This is not only for PCs, but for a whole slew of other things as well like mentioned.

it was supposed to be HDMI for PC only.... i have a 300 pages document about this and the intention was pc no consumer electronics

[Magnj]

I thought HDMI was gonna be PC too?
Oh I'm so confused

[MaxxxRacer]

HDMI will appear on some video cards as it will be used for HDTV HTPC's.

[Stuperman]

Oh I'm so confused

Display Port, HDCP, HDMI, DVI-I, DVI-D, some have DRM, some don't

nothing more to say :p:

...things would be so easy if both, tvs and pcs, would use one solution...

remember there is a difference between good and bad invention..;)

[STEvil]

and right now everyone is offloading their bad stuff into the PC world.

[MaxxxRacer]

yup.. one's good and the other's bad....

and a Unified standard for both TV's and computers would be great.. Personally I dont see why they didnt use DVI for Tv's.. it has analog and digital built into it. the current HDTV plugs are absolutely retarded...

[perkam]

I'm sure this has been covered, but I couldn't find it so I will ask.

What is the bandwidth for DisplayPort? With DVI, we ran into a wall on the size of displays that could be driven with just one port. Did the standards group learn their lesson, or are we going to have a repeat in 5-7 years? Picture of DisplayPort added in first post.

I was asking about video bandwidth, but thanks for the pic. ;)"The Main Link bandwidth enables data transfer at up to 10.8Gb/s using a total of four lanes."

man and I just bought a new 19" LCD with dvi-d!

Now can't you use an adapter between hdmi and dvi? They sell those for the tv's, why not for pc?

It's not like we are going to get this as a standard anytime soon :P

I don't understand what was wrong with HDMI, or what DP has as an advantage. I mean damn, are we going to end up having GPU's with 4 different ports on the back or *have* to become a slave to an adapter?

I can't really see either large GPU company wanting to produce various cards, some with VGA/DVI, some with VGA/HDMI, others with HDMI/DVI, others with.. etcetera.

[Elder Young]

Correct if I'm wrong on any of this.

VGA transmits only an analog signal and can be used for monitors and consumer electronics (TV's, projector, etc).

DVI-I can transmit either digital or analog signal, depending if a VGA adapter is used. DVI-D only transmits a digital signal. DVI can be used for monitors and consumer electronics. DVI requires dual link transmitters to display high resolutions on large monitors. DVI only transmits video. DVI has a fairly sturdy connection. HDCP is uncommon on computer monitors, but basically required for consumer electronics.

HDMI only transmits digital video and can transmit various digital audio formats, depending on the revision. HDCP is required for HDMI and HDMI is currently only used for consumer electronics. HDMI has a smaller connector than DVI, but the connection feels kind of flimsy (it doesn't lock in place). Also, there seem to be problems with devices "handshaking."

DisplayPort will transmit digital video and maybe audio(?), I'm assuming with HDCP as a requirement. It will have a small connector like HDMI, but optional latches to make the connection feel more secure. It will have over twice the bandwidth of HDMI (10.8Gb/s vs. 5Gb/s) and can be used for computers and consumer electronics.

Since sound and video come from two different sources in a computer, I don't see why it would be useful to have DisplayPort transmit audio, unless sound cards and video cards could easily communicate with each other (maybe one DisplayPort connects the two cards externally, like Crossfire, or 3dfx SLI, and another DisplayPort transmits to the display). If it does support audio, then DisplayPort sounds like what HDMI should have been, current HDMI+better connector+more bandwidth. If not, it sounds like DVI+smaller form factor+more bandwidth.
