    Today, many users are discovering that they can dramatically increase efficiency by connecting several monitors to one PC.

    The Multihead ServSwitch™ supports multiple monitors. When you switch between CPUs on this ServSwitch, you see all the monitors connected to each CPU—up to four monitors per CPU. So you always get the entire view.

    Imagine what you can do with more monitors connected to your PC. You can put each of several applications on a different monitor to eliminate tedious switching between applications. Or if you have an application that uses lots of small windows, you can expand it across several monitors to provide more work space.

    The Multihead ServSwitch is compatible with all IBM® PC/AT® or PS/2® type CPUs and most major operating systems including Windows® 3.x/95/98, Windows NT®, Windows 2000, UNIX®, Linux®, NetWare®, and OS/2®.

    The switch supports video up to 1990 x 1400 over coax cable at distances of up to 10 feet (3 m).

    For other distances and resolutions, or for compatibility questions, contact Tech Support.
