VGA, DVI and LVDS set for execution

Some of the world's more prominent chip and display makers have banded together and vowed to squeeze legacy display interfaces from the market as early as 2015.

AMD, Dell, Intel, Lenovo, LG Display and Samsung Electronics have all renewed vows to accelerate the adoption of HDMI and DisplayPort display interfaces and root out the feature-limited display standards.

Both AMD and Intel have set dates on the extinction of VGA, LVDS and DVI-I, and the panel manufacturers will follow suit. Removing digital-to-analogue circuitry will save space and shave off a few watts of power consumption, claim the companies involved.

The deadline for VGA and DVI-I extinction for both Intel and AMD is set to 2015, while LVDS will meet its death by 2013.

The line between LCD TVs and PC displays has become increasingly blurry, the industry remains committed to prolonging the conflict between HDMI and DisplayPort. In the immediate future, HDMI 1.4a and DisplayPort 1.2 will be driven to be the TV and PC standards, respectively.

While one might consider the need to protect digital content as one of the driving forces behind all-digital standards, there are some advantages to be had by dropping the analogue altogether, a bit like the 'resounding' success of digital TV. For example DisplayPort, the most fully-featured of the standards can provide a wider range of functionality, including: Direct Drive (that will remove some power-consuming circuitry from display panels) and full-bandwidth DisplayPort hubs for Eyefinity-like output, amongst other neat tricks.
