DisplayPort to do DVI to death, analyst claims
And HDMI to pass water on DisplayPort?
Market watcher In-Stat reckons DisplayPort, the new PC-centric monitor connection system will trounce DVI to feature in 600m shipped products in 2012.
Earlier this year, In-Stat forecast that DVI will be included in just 3m devices by 2011, down from 112m in 2007. In the main, that's because vendors will opt instead to fit DisplayPort connectors.
A DisplayPort connector... unconnected
It's not hard to see why: DisplayPort is all-digital so there's no analogue backward-compatibility baggage. The connector's a darn sight more compact than DVI, making it particularly preferable on laptops. And it has the bandwidth to deliver larger resolution images, with a greater range of colours and sound.
DisplayPort monitors and graphics cards are already available, but don't expect to see too many more this year, In-Stat said. But that will change over the next couple of years.

Or will it? DisplayPort isn't the only all-digital offering: HDMI does much the same job and, crucially, is compatible with DVI, which DisplayPort isn't. In-Stat reckons that almost 90 per cent of the digital TVs that shipped last year included HDMI ports, and it's hard to imagine that number not increasing this year.
Some 143m HDMI-enabled devices shipped in 2007, In-Stat has calculated, a fair few of them media-oriented PCs. Then there are the many DVI graphics cards that now come with HDMI adaptors.
DisplayPort's advantage is that it's aimed at connecting PCs and monitors, whereas HDMI was developed to link HD TVs, media players and set-top boxes. There's no question that HDMI has come to dominate the consumer electronics market.
But since both technologies do essentially the same job, will it also rule the computing roost? In-Stat's own prediction is for 229m HDMI-enabled devices to ship in 2008, a 60.1 per cent increase on 2007's total. By 2010, that figure will have jumped to 1.2bn - more than double the projected figure for DisplayPort two years further on.
freetards of the world unite.
As usual, the AC freetards that think the world can operate without DRM. HDMI works. Live with it.
I suspect the AC freetard is the same Xbox freetard..
"The only real difference between linking with RGB versus S-Video is where the conversion to RGB is done, in the TV or in the DVD player, and the respective quality of those circuits."
I would suspect that it is the difference in those circuits that make a difference but people migth not know it - and so some people might see a difference and tribute it to the RGB cable. In my own previous setup using a Sony Trinitron TV it certainly made a huge and visible difference - and I only had cheap cables connected... But then most of the equipment I used might not have been of particularly great quality overall.. But still - when the RGB was used the picture was better...
The same thing goes for HD - it has a lot to do with the particular circuits used and in the actual implementation - I have seen many HD TVs which have a very poor quality picture. Poor quality in many pixels... is not necessarily better than good quality in few(er) pixels...
"i hope you mean you use s-video for pc to Tv connections not for any dvd to tv etc connections. if so get yourself an RGB scart and see a massive quality difference"
Not so much. The encoding on a standard DVD is YUV, i.e. component, with the UV part substantially reduced in bandwidth during the encoding since the human eye is must less sensitive to colur then brightness. S-Video (Y/C) just encodes the UV into a single C(hrominance) signal with very little additional loss.
The only real difference between linking with RGB versus S-Video is where the conversion to RGB is done, in the TV or in the DVD player, and the respective quality of those circuits.
Of course, if you've spent £200 on a gold-plated RGB SCART cable, you'll certainly want to believe there's a difference, but... :)
Only if it overcomes hdmi's problem
Why can't they create a small connector that doesn't fall out!!! if I move my sky box, even a few cm's out comes the HDMI lead.
now if they could put those clips like on SATA I would be happier :)
VGA and DVI are both big and chunky. They stay in because there's room for big arse screws to hold them. They don't break easily because there's enough strength in the connectors to withstand most bumping and knocking.
Displayport's connector alone is crap. Too small, which means it will break, has less options for holding it in, etc. It's not a good thing to have such a connector as a tiny one. One bump and it's out, and possibly snapped.
DVI and HDMI can co-exist nicely, and that's about all we need.
