What is Virtual Display Technology (VDT)?

Virtual Display Technology (VDT) is implemented in HSL Secure KM
switches series to enable seamless cursor and keyboard switching
between multiple displays. VDT allows administrators to configure
any desired displays configuration with same or different size and
resolution. User simply moves mouse cursor across neighboring
displays to switch between connected computers.
Refer to the example in the figure at the right side. Assume that
computer #1 is connected to the left display, computer #2 is
connected to the top display, computer #3 is connected to the center
bottom display and computer #4 is connected to the display at the
right side. In this example all four displays are identical. VDT allows
the user to move the mouse cursor across the four displays while
automatically switch the shared peripherals based on the current
cusrsor location. For example when the user moves the cursor from
the left display to the center bottom display, the KM identifies the
display boarder crossing between these two displays and switches
the KM to computer #3.
HSL VDT is now further enhanced with the inclusion of pointing
device drivers to support dual, triple and up to 16 head computers.
With this technology user workstation may be integrated with any
combination of single, dual, triple and quad head computers.
VDT Configurator software enables the user administrator to easily
configure any set of display sizes, resolutions, geometry and physical
arrangements.
