Engineers construct 220 million pixel computer display

Engineers at the University of California, San Diego have constructed the highest-resolution computer display in the world – with a screen resolution up to 220 million pixels.

The system located at the UCSD division of the California Institute for Telecommunications and Information Technology (Calit2) is also linked via optical fiber to Calit2’s building at UC Irvine, which boasts the previous record holder. The combination – known as the Highly Interactive Parallelized Display Space (HIPerSpace) – can deliver real-time rendered graphics simultaneously across 420 million pixels to audiences in Irvine and San Diego.

“We don’t intend to stop there,” said Falko Kuester, Calit2 professor for visualization and virtual reality and associate professor of structural engineering in UCSD’s Jacobs School of Engineering. “HIPerSpace provides a unique environment for visual analytics and cyberinfrastructure research and we are now seeking funding to double the size of the system at UC San Diego alone to reach half a billion pixels with a one gigapixel distributed display in sight.”

Kuester is the chief architect of the systems deployed in both Calit2 buildings. Until last week, UC Irvine’s Highly Interactive Parallelized Display Wall (HIPerWall) – built in 2005 with funding from the National Science Foundation (NSF) – held the record of 200 million pixels for a tiled display system. It is located in the Calit2 Center of Graphics, Visualization and Imaging Technology (GRAVITY), which Kuester directs. When Kuester’s group moved to UCSD in 2006 they began work on the next generation of massively tiled display walls, which now serve as a prototype for ultra-high resolution OptIPortal tiled displays developed by the NSF-funded OptIPuter project (led by Calit2 director Larry Smarr).

The new HIPerSpace system between Irvine and San Diego is joined together via high-performance, dedicated optical networking that clocks in at up to two gigabits per second (2Gbps). The systems use the same type of graphics rendering technology, from industry partner NVIDIA. The “graphics super cluster” being developed at……. Read the full Article from the source:
