The largest dedicated computer monitors are used for specialty operations such as medical imaging, air traffic control, security, and utility monitoring. Consider Barrco’s NSL-4601. Although it is comprised of four tiled LCDs, its total size is 46 inches. At a cost of nearly $6000, it carries a considerably large price tag, but it is still a far cry from the biggest of the big.
Moving beyond this size range brings us to the realm of LCD panels that function primarily for HDTV viewing, but can still be viably used as monitors for computer video. Check out the Sony KDL-70XBR3. According to the specifications, it has inputs for composite, S-video, and component video. Weighing in at 204 pounds, (including its pedestal) with a 70 inch screen, and a price of $33,000, this monster monitor makes the Barrco NSL-4601 look puny by comparison. However, it’s still not what could be considered the biggest computer monitor.
