APPLICATION GLOBAL
Purpose of this interface is to take RGB signals from a computer and to display them on a large screen
projector, while keeping the image on the monitor intact.
As IBM and Apple computers need monitor identification for soft and hardware configuration purposes,
emulation of these identification bits is provided in case no monitor is connected.
In case a monitor is connected, the identification bits of the monitor are fed to the computer.
To obtain the best performing images on the large screen-projecting device, active loop-trough is used
for the monitor output.
RGB signals from the computer are automatically terminated to 75 Ohm, while sync signals, which are
TTL signals are terminated with a 22K pull-up resistor.
