In the spy business, a 22-inch computer display gets you only so far. Intelligence agencies need displays capable of covering the entire wall of a command and control center. Mersive develops software that's used to create large, "ultra high-resolution" displays for use with pixel-rich applications. The company's website shows its technology being used in the White House situation room, Washington Metro's command and control center, and DOD's Joint Tactical Air Controller dome. An In-Q-Tel investment aims to create a new class of these displays for intelligence agencies.
