PC picture will sharpen

Desktop PC technology has made huge leaps in the past decade. Computer monitors lag in comparison. But that may change soon as the PC industry moves CRT (cathode ray tube) technology from an analog world to a digital one.

A new industry standard, called digital video interface (DVI), offers to solve nagging monitor problems like jitters, ghost images, and image distortion. The standard will do for computer monitors what high-definition television is expected to do for the boob tube, says Ed Anwyl, an IBM marketing manager.

IBM announced Tuesday that it supports the new DVI specifications in its Aptiva S Series, which is now available. IBM representatives say its PC 300 and IntelliStation desktop PCs, and both its P Series CRT monitors and T Series flat-panel displays will be infused with the technology by the end of September.

A group of PC, monitor, and graphic chip makers said this week at Intel's Developers Forum that they too will support DVI specifications. Called the Digital Display Working Group and led by Intel, the industry coalition includes IBM, Compaq, Dell, Microsoft, and Silicon Image.

The standard should not only eliminate common problems with monitors, but also improve the image, IBM's Anwyl says. Creating a consistent digital signal from a computer to a monitor should boost the resolution and crispness of images. The standard will eventually link PCs, consumer electronics devices, and other systems to a digital display.
