professors at UC Irvine have built what they claim is the highest-resolution video screen.
The university's 23-by-9-foot Highly Interactive Parallelized Display Wall consists of rows of linked monitors, each of which displays a portion of the picture. It can manage 200 million pixels.
Stephen Jenks said that the picture his team developed is more than 100 times more detailed than the best high-definition TV. IT has a higher resolution than the human retina can see."
According to the LA Times the wall was designed to observe changes in the individual brain cells of schizophrenics, predict climate change by comparing a century's worth of weather models and study the cells of a woman who died of ovarian cancer.
