5. Front Panel Control
5.1 Multi-views Selection
Factory default is four quarter views, and factory default input and output corresponding
relation is input1 -> window A, input2 -> window B, input3 -> window C, input 4->
window D. Press one of the other two multi-view buttons to change layout. And its
multi-view mode and corresponding windows LEDs illuminate blue.
Full Screen mode: Press Windows A~D button to select the corresponding window to
display in full-screen. Meanwhile, the corresponding input source button LED and
window button A LED illuminate blue, other window buttons and previous multi-view
mode button LED goes out.
5.2 Video Signal Switching
In the Multi-view mode
Operation: Inputs# + Windows#
Example: Switch Input 1 to Windows B:
Press INPUT 1(The input 1 LED illuminates blue, the windows A-D LEDs flash.)
Press Windows B (The windows A, C and D LEDs go out, then input 1 and windows B
LED flash three times, last, input 1 LED goes out and windows A-D LEDs illuminate
blue.)
In the Full Screen mode
1) Manual Switching
Operation: Inputs# + Windows#
Example: Switch Input 2 to Windows A:
Press INPUT 2 (The input 2 LED illuminates blue.) Press Windows A (The input
2 and windows A LEDs illuminate blue).
2) Auto Switching
Press AUTO button to enter auto-switching mode, and the corresponding LED
illuminate blue.
When in the AUTO mode, signal switching complies with the following principles:
Four input sources priority: HDMI 1 > HDMI 2 > HDMI 3 > HDMI 4. When input
source and output window are connected, the corresponding LEDs illuminate blue.
Once detecting a new input signal, the switcher will switch to this new signal
automatically.
The switcher will memorize last input source when power off
Manual switching is enabled in the auto switching mode and does not exit it.
