A 10-foot-high, 13-foot-wide screen that makes high-definition television look as grainy as an old TV in a cheap motel has been unveiled by Sandia National Laboratories. The facility’s digitized images, created of 20 million pixels, approach the visual acuity of the eye itself. The new screen is not only the clearest but also, says manager and program leader Philip Heermann, “to my knowledge the fastest in the world in rendering complex scientific data sets.”
