Goodbye DVI and VGA, DisplayPort is Here
By Nate Mook | Published April 4, 2007, 4:48 PM
While it still may be a few years before we can officially wave goodbye to VGA and DVI, the Video Electronics Standards Association (VESA) today announced approval of DisplayPort 1.1 as the new industry standard for flat panel displays, projectors, PCs and consumer electronics devices.
DisplayPort 1.1 most notably adds support High Bandwidth Digital Content Protection (HDCP) version 1.3. HDCP is the copyright protection technology required by both Blu-ray and HD DVD content, which prevents the digital video signal from being hijacked and recorded to unprotected media.
The new standard is designed to eventually replace LVDS, DVI and VGA, and manufacturers are already clamoring to adopt it. The reason is simple: DisplayPort utilizes a single digital interface for connecting both internal and external displays. This means that DisplayPort can carry pixels directly from any display source to any LCD panel.
Other advantages of DisplayPort over DVI and VGA include a small USB-sized connector with available latching, two-way display connectivity, optional audio support, higher performance than dual link DVI at 10.8 Gigabits per second, and a unique micro-packet architecture that enables new display features.
“The benefits of version 1.1 are significant, and will encourage adoption of DisplayPort in new generations of computers and consumer electronics equipment,” remarked VESA executive director Bill Lempesis in a statement. “Our task groups and committees within VESA worked very hard to ensure that DisplayPort 1.1 satisfies the important objectives it is designed for, and as a result, this new version has widespread support among all the leading computer and consumer electronics suppliers.”
DisplayPort 1.1 will be available as a free and open standard, VESA says. The group is also finalizing guidelines for providing DVI and HDMI connectivity via the DisplayPort connector, which first appeared at CES 2007 in January.
SanDisk are pushing an open standard that combines USB and TV pins, I saw a awesome demo at CES 2007

|We have too many standards for audio and video signal connectivity. What I would like to see, personally, is to have an option to combine audio, video and control signals, and have one cable that will carry all the signals in digital format. Good bye messy cables!
"... small USB-sized connector with available latching, two-way display connectivity, optional audio support" and "a unique micro-packet architecture that enables new display features" statements are vague, but, probably, assume such capabilities.
I am wondering how easy and how expensive would it be to split (cable/sat receiver to TV/Display, video recorder, audio system, etc.), switch (cable/sat receiver or video player to TV/Display) and repeat or carry signals over relatively long distances (another room). Standard audio/video devices usually have limited number of connections (typically, 2-3), and connecting new devices may be costly, especially when connecting with legacy devices.

|Is Sony going to come out with their own proprietary version of the DisplayPort to screw up adoption, like they did with HD DVD?
Score: 0
|What?
HD-DVD was launched almost a year AFTER Sony's Blu-Ray technology format was announced.
Score: 0
|Where do you get your false information? The two technologies were competing against each other. The DVD Forum made their decision and Sony lost, and the winner got the HD DVD name. Now Sony is trying to force their entry on us and made up a name of their own, Blu-Ray. If Sony had not done this, HD DVD would be adopted unhindered, but thanks to Sony, everyone is now afraid to buy either one in fear they may choose the loosing format. So it’s win win for Sony because they are not only getting revenge for loosing, but they also may actually still win the war. So it now looks like regular DVD will be around much longer than expected. Thank you for the chaos Sony.

|You definitely have this backwards. HD-DVD may sound like the natural successor because it contains the familiar Digital Versatile Disk in it's name. The competing standards name helps perpetuate the ignorance and it actually was created well after Sony's new format.
You should also know that the format is not proprietary but available for the current manufacturers of HD-DVD to adopt any time they choose. Since the technology is far superior it does require an expensive upgrade to the manufacturing process over the former DVD assembly lines. In contrast HD-DVD makes use of most of the older equipment with reduced data capacity per disk.
FYI, Sony also created the original CD and DVD formats which were quickly adopted industry wide by multiple manufacturers and never proprietary.

|Why not buy both? Then you have nothing to complain about. People like to be on the BD side or HD-DVD camp so they can complain and say how much the other one sucks.
You can get a PS3 and a 360 core with an HD-DVD for less than the cost of a dedicated Sony BD player and you have two decent video game systems as well. Now you dont have to be a Sony or 360 fanboy. No, thats too complicated. Let's all buy one and b**** about the other.
Wait, I need to stay on topic.
HDMI still sucks and always will. It's for the lazy slobs who only need to plug thier DVD directly into their TV. Even Comcast refuses to use the HDMI port on thier boxes because of handshake isuues with a lot of plasma manufacturers.

|Just wait! Comcast has an even nastier new tech coming that they are already whining about. Cable Card is already implemented in many new systems and it's a matter of time before cable companies have to provide the cards to customers with "compatible" units.
This is some-what on topic since we are talking about plugging cable directly into the TV and thus removing the DVI, HDMI, Coaxial, RCA, S-Video or DisplayPort cables.
Jezus I remember the good ol' days when we only had two screws on the back of the TV (four once UHF came out) and we twisted little wires around them...

|The Sony and Philips Corporations developed the compact disc in the early 1980s.
In the early 1990s two high-density optical storage standards were being developed; one was the MultiMedia Compact Disc, backed by Philips and Sony, and the other was the Super Density disc, supported by Toshiba, Time-Warner, Matsus***a Electric, Hitachi, Mitsubishi Electric, Pioneer, Thomson, and JVC. IBM's president, Lou Gerstner, acting as a matchmaker, led an effort to unite the two camps behind a single standard, anticipating a repeat of the costly format war between VHS and Betamax in the 1980s. Philips and Sony abandoned their MultiMedia Compact Disc and fully agreed upon Toshiba's SuperDensity Disc.
On 19 November 2003, the DVD Forum voted to support HD DVD as the high definition successor of the standard DVD. At this meeting, they also renamed it HD DVD. The format had previously been called the "Advanced Optical Disc" (AOD).

Yes I'm being picky, but digital output is not always LCD. There are many digital technologies, and many of which will have replaced LCD by the time this standard becomes widely used.
I'm even typing this on a DLP projection screen, and it is digital and not LCD and it is 3 years old.
Score: 0
|Even though you have a DLP projector, it uses a pixel matrix internally to project the image. My understanding of the standard is that signal carry per-pixel information to the display, and will be suitable to connect display devices regardless of their resolution. Display capabilities, including resolution, will be negotiated between display and video source, and video source can perform rendering of video images that will produce best display picture.
You can argue that DVI and HDMI standards already implement that. However, technology must be at the level when these standards no longer satisfy the needs of the audio/video industry, and offer no room for expansion. It is like comparing RS232, USB, Fireware and all flavors of Ethernet. In this essence, DisplayPort is like Gigabit Ethernet compared to the other standards, but optimized for streaming video.

Really? There is no processing involved and there was already an interconnect, of which this is simply a new format allowing for the convergence and the addition of other functions.

Right now, there is not one form of digital media that you can't make a copy of. Copy protected CD's...no problem, copy protected DVD's....no problem, HD-DVD...a little work but no problem, Blu-Ray....same thing.
The problem is the general public is too stupid to know they are being screwed. The industry makes Best Buy and CC salesman tell people that HDMI is state of the art and the best possible connection, and they believe it because they dont know s***.
Then they sell you an overpriced Moster Cable HDMI when most devices come with one these days on the premise that the Monster Cable version somehow gets 1's and 0's to the monitor in a superior way.

|They sell these things much too often, I agree, but it's been pretty much proven to display an image that far surpasses the display of regular cables, doesn't it? (honest question) I'd never buy them because they're a freaking bottomless money pit, but for those willing and able to spend the money, they'll receive at least a SLIGHT increase in information processesed, no?
I guess it's like the 'electrical noise reducers' they sell. It's the same thing. They update the connection so it can handle more, but then cripple the ability to do other things. I think it'd be great if they failed miserably, but most people will buy it up without any qualms because it IS a superior technology. For what *they* are using it for, also, they're not going to notice there's no way to copy the info off their disks anymore. Not enough people do that anymore. There's only a few that actually PROVIDE the stuff we download today, so it'll only affect the geeks that are able to rip that stuff away.

|It all depends on the particular tv and the capabilities of the device sending out the signal. HDMI does not give the most prestine images on everything. It's the same thing with component connections. Just because a tv has the connection available, that doesn't make it worth using.

|Another brainwashed zombie. Did Best Buy tell you HDMI is better Joey? Did you put down $100+ on that "special" Monster HDMI cable? One of the foremost home theater designers in the world thinks that HDMI is a complete joke. Did you ever try to get a Runco plasma and five other devices to handshake properly through an ADA switcher?
Of course not. The extent of your expertise is a BOSE 321 and a "home theater" consisting of a 40" LCD and an Apex DVD player. Don't sit here and tell me what the **** I dont know. We have ripped out more HDMI only systems that you will ever know and replaced them with all with component video switching. Why? Because HDMI is a ****ing nightmare when it comes to real systems, not you running one cable into your wannabe home theater Best Buy sales ad special of the week.
Do you honestly think that the digital proccessing on the HDMI end of a Dell or Pioneer plasma is actually worth a s***? Those parts are supplied by the lowest Chinese bidder. The only great HDMI proccessing out there is in very high end, expensive projectors. If you werent so ****ing broke and stupid, you would know the difference. If it doesnt have the name Faroujda attached to it, it's s***.
I've got boxes of these useless cables laying around, the connector sucks, you can't terminate them in the field and the distance limit is about 20 feet. Great idea though. Next time you try to wire up a 30,000 square foot house with an eight rack distributed video system, try using HDMI and let me know how it works out.

|Guys. guess what? eventually you won't have a choice if you want high resolutions. Displays and cards aren't going to come with Dual DVI forever, and eventually resolutions will scale.
This doesn't impact your current content at all.
It will impact your content in the future. but also
guess what?
Not many pirates care about this, because nobody steals the signal from the video, they steal it from the data source itself or it's memory location.
So this will have nil impact on content "availability," however it will raise the price in the short term.

|There is no reason graphics card manufacturers can't use superior HDMI instead. When it comes to graphics, the only difference between DVI and HDMI is the connector. Otherwise they are identical.
It is nice that compatibility with DVI and HDMI is in the works though because originally DisplayPort was going to be a proprietary connection that would not be compatible with DVI or HDMI.
