IBM First With PC Supporting DVI Digital Video Interface.

IBM Corp has announced the first PC to include support for the new Digital Visual Interface graphics specification, supporting both existing analog VGA monitors and the emerging brand of digital monitors, including thin film transistor flat panel monitors. The Aptiva S Series includes a single common connector between the machine's built-in DVI port and both analog and digital monitors.

The new interface will enable systems to support greater graphics bandwidth, improved signal quality, hot-plugging capability and monitor asset management, according to IBM. VGA monitors, now 12 years old, are certainly showing signs of age, and it's getting harder to maintain the signal quality and sufficient bandwidth as support for more pixels is added. The DVI specification was developed by the DDWG, formed last year at the Intel Developer's Forum with the backing of Intel Corp and Microsoft Corp, in an attempt to push forward standards efforts for digital monitors. Japan's Digital Interface Standards for Monitors (DISM) group agreed to work with DDWG last November. It uses Transition Minimized Differential Signal technology developed by Silicon Image Inc, electronically compatible with the VESA Plug & Play and Digital Flat Panel standards. The group chose to work outside of VESA for time to market reasons. DVI "has a lot in common with P&D but tales it further" an IBM spokesperson said.

IBM says it will add DVI support to further products later this year, including other Aptiva consumer models, PC 300 commercial systems, IntelliStation workstations, P series CRT monitors and T series TFT flat panel monitors. Other product lines, such as t he ThinkPad and Retail Store Solutions, will be supported in 2000. The Aptiva S has a starting price of $2,000. At the Intel Developers Forum this week, details about the future of the specification, including encryption support (important for content owners who want to maintain the copyright protection of a DVD movie, for instance), are expected to be revealed.
