The video electronics standards association (VESA) has announced the publication of VESA’s display identification data standard (DisplayID) version 1.3. The latest version of DisplayID now includes support for resolutions at 4K and beyond, tiled display topologies, stereo 3D formats, high pixel densities and additional timing standards.
“Every day, increasing transmission rates, video resolutions, PPI and processing capabilities are making new display capabilities available to consumers. Our vision for DisplayID was to define a standard that can easily keep pace with a rapidly expanding universe of display options. With DisplayID, video sources – like computers, game consoles, cable boxes and video players – can easily discover the capabilities of the monitors they are connected to, enabling an automatic and seamless user experience between devices,” said Syed Athar Hussain, display domain architect for Advanced Micro Devices and VESA vice-chairman.
The DisplayID standard was developed by the VESA members to define data structures that a video display uses to describe its physical and performance attributes. Encoded into a display EEPROM, DisplayID enables a video source to discover these display attributes, and to customize its video data stream output for the unique capabilities of an individual display.
DisplayID was developed as the evolutionary advancement for VESA’s widely adopted Extended Display Identification Data (EDID) standard. Designed specifically to be ‘future-proof,’ DisplayID employs flexible header and data structures that can be of varying length and number, in contrast to the fixed header and data structures used by EDID. The flexible, modular data structures defined by DisplayID enable new definitions to identify new display resolutions, refresh rates, audio standards and other formats and capabilities. One of the more exciting new capabilities, tiled displays, supports a single display that uses multiple video processors, with each video processor handling the image on one segment of the display. The latest 4K @60Hz monitors now entering the market offer four times the resolution of conventional high-definition TV; these new 4k monitors frequently employ tiled displays to enable a more optimized system level solution that satisfies the higher resolution trend.
“Display manufacturers are starting to develop advanced technologies, including 8K ultra-HD displays and displays that incorporate multiple video processors. These new display capabilities need to be identified and defined within the DisplayID standard for effective inter-operability and ease of use with other consumer and computer systems. Keeping standards at the forefront of technology enables manufacturers to deliver the latest capabilities in display technology to the consumer. VESA is proud to be an association that propels advancements within the display interface industry,” said Bill Lempesis, executive director at VESA.
