Section 2 - Overview

What is Virtual Display Technology (VDT)?

Virtual Display Technology (VDT) is implemented in HSL K300 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.
