The struggle between DisplayPort and HDMI continues

This week marks an important move forward for the DisplayPort special interests group as the Video Electronics Standards Association (VESA) has officially approved DisplayPort version 1.1 as an industry standard. Despite the approval, there is an ongoing struggle in the graphics industry about which technology will make the cut as the de facto high-definition PC interface: DisplayPort or HDMI.

According to VESA, the DisplayPort standard has come quite a long way. "DisplayPort 1.1 gives manufacturers of LCD panels, monitors, graphics cards, PC chipsets, projectors, peripherals, components, and consumer electronics a next generation digital interface that is designed to replace LVDS, DVI, and eventually VGA," said the statement.

VESA indicates that the benefits of DisplayPort are significant and important, and that the group thinks DisplayPort will be integrated into many next-generation PCs. "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."

Major developers like AMD, NVIDIA, HP, Intel, Lenovo and Samsung have said that they will fully support DisplayPort. According to the release:
Available throughout the industry as a free to use, open and extensible standard, DisplayPort is expected to accelerate adoption of secure digital outputs on PCs, enable higher levels of display performance, and introduce high volume digital displays that are simpler, thinner, and easier to use than VGA.
On the other end of the spectrum, the groups backing HDMI argue that while there are valid features in DisplayPort, HDMI can do everything that DisplayPort can and more. The most pominent factor however is the fact that DisplayPort doesn't have solid definitions for licensing. Although the DisplayPort group claims that there is little to no fees, the HDMI group points out that there are also no restrictions on adding in fees at a later date.
