A cable that is designed to be able to provide a high definition video connection from a computer to a display is on show at Intel's Developer Forum, and both Apple and Intel are part of the industry consortium behind its creation.
It is intended that the cable will replace the old VGA (video graphics array) interface with a new connection that can accommodate high-end video content. The connector doesn't carry audio in the way that a HD connector to a television set would, because the computer will deal with the audio side, explained a spokesperson.
Sophisticated modern PCs with discrete graphics chipsets like Nvidia's use the DVI (digital visual interface) to connect to digital displays. High-definition televisions use a standard called HDMI (high-definition multimedia interface) to obtain their images from set-top boxes or receivers. The two standards are compatible, but HDMI offers some additional features, such as universal remote control, and can handle more traffic over a single cable.
But many low-cost PCs still rely on the analogue VGA standard to connect to monitors. VGA is good enough for those PC users who are simply browsing the internet, but DVI connections are needed to watch videos stored on a home PC on a digital display.
UDI promises to bring the features and functionality of HDMI, not to mention its copy-protection technology, to mainstream PCs, the UDI SIG said. UDI will use the same HDCP (high-bandwidth digital content protection) technology used by both the HDMI and DVI standard, and it will be fully compatible with the two existing standards, the group said. Therefore, UDI PCs will work with HDMI televisions or DVI digital displays, it said.
