6.1 Video-Switching
6.1.1 Windows in the four equal parts mode.
If want IN1 to windows B output, first, press button IN1 and its corresponding LED keeps
on, but the LED of A,B,C and D keep blinking, and then press button B and its LED
always is on and LED of A,C and D are off. At this time, the IN1 LED and B LED blink 3
times to finish video-switching. Lastly, the IN1 LED is not blue and LED of A, B, C and D
keep on.
6.1.2 Windows in full screen mode.
Manual-Switching
For example, if the full screen is A and its LED keeps on, and then want IN2 to windows
A output, firstly, press IN2 button once, the corresponding IN2 LED turns blue
