I saw this today. Not completely Widescreen related, but it has it's purpose.
Matrox Graphics Inc., announced today the Extio F1220, the latest addition to the Extio series of Remote Graphics Units(RGUs). The Extio F1220 enables the extension of one or two displays with resolutions up to 1920 x 1200 per monitor, audio, two IEEE 1394 FireWire ports, and up to six USB devices(4 at the front, 2 at the back), including keyboard and mouse, by up to 820 feet(250 meters). By separating the computer from the monitors and user-interface, the Extio series of products helps address issues such as security, heat, noise, system maintenance and support, and system access in digital signage environments. The Extio F1220 RGU has no moving parts. It is connected to a Matrox PCI or PCI-Express Extio adapter card in a computer, workstation or server slot via a standard multi-mode fiber-optic cable with Dual-LC connectors. Matrox Extio F1220 will be available in the second quarter of 2007.
