Digital visual interface (DVI) and high-definition multimedia interface (HDMI) are related high-bandwidth, unidirectional, uncompressed interface standards, while DisplayPort is a fully digital, packet-based technology.
HDMI and DisplayPort have recently gained in popularity within the computer industry. A number of computer vendors and display makers have said that they will stop using legacy DVI and VGA connectors within the next few years.
Nevertheless, many devices are still shipping with DVI connectors. According to the latest market study by NPD In-Stat, they forecast that the combined total number of devices shipped with DVI, HDMI, or DisplayPort will surpass 2 billion in 2015.
"DVI has no roadmap to upgrade the specification; it is essentially the same as it was upon its launch in 1999," said Brian O'Rourke, Research Director at NPD In-Stat.
HDMI and DisplayPort, on the other hand, have made significant strides in a number of markets. HDMI-enabled device shipments will increase at a 17 percent annual rate through 2015 and DisplayPort-enabled device shipments will reach 1 billion.
Other details from this market study include:
- Embedded DisplayPort will have a 95 percent attach rate in notebook PCs in 2015.
- 19 million desktop PCs will ship with DVI in 2012.
- HDMI will have a 94 percent attach rate in Blu-ray players in 2013.
- Over 118 million external DisplayPort-enabled tablets will ship in 2015.
