Besides ATI, NVIDIA has also put in its support for DisplayPort. Other consumer electronics companies such Philips and Samsung are also supporting the new standard. DisplayPort, says ATI, will become the next major standard due to its high-bandwidth and low latency capabilities. Technically, DisplayPort takes on some other features of HDMI, which is based on DVI but also has lines to carry a multi-channel audio signal. DisplayPort too will also be able to carry audio as well as a high-bandwidth signal that will be able to display an image with a higher resolution than even dual-link DVI (2560×1600).
It probably won’t be a little while until we actually need to worry about this.. a year at least. It does have some benefits over HDMI though, so it may not be such a waste of time as many are making it out to be. As always, time will tell. Check out the posting at DailyTech.
