The MD5x1 is equipped with two RGBHV inputs for receiving a computer’s RGB
video output signal. These ports can automatically detect the presence of an RGB
signal using the H-sync signal on pin 13 and can sync on the H signal on pin 13 or
the V signal on pin 14. A buffered pass-through port for connecting a secondary
computer display is connected to the port labeled RGB 4. Refer to the following table
for pin-assignments.
