2.1.1 VESA Analog
The video input consists of red, green, and blue signals. The video signals are analog levels, where
0V corresponds to black and 700mV is the maximum signal amplitude. Input impedance of video
pins is 75 ohm ±1%.
Sync signal input
The capability of sync signal inputs shall include separate sync. Input impedance: 2k2 ohms the
signals are defined as follow:
Separate sync TTL level, Positive/Negative
