5.2 Automatic Switching

Press and hold the AUTO button at least three seconds to enable automatic switching, and the Auto mode LED will light.

When in the Auto mode, the switcher will switch according to the following rules:

• The switcher will switch to the first available active input starting at input 1 to 6.
• New input: The switcher will automatically select the new input once detecting a new input.
• Reboot: If power is restored to the switcher, it will automatically reconnect the input before powered off.
• Source removed: When an active source is removed, the switcher will switch to the first available active input starting at 1-HDMI/MHL input.
• Press the Video Source button (1, 2, 3, 4, 5 or 6) can directly change the input source. If the corresponding source device is active, it will be switched as input source; otherwise, the switcher will switch to the first available active input starting at 1-HDMI/MHL input.
• Press and hold the AUTO button at least three seconds again can exit AUTO mode, but the input source will remain the current setting.

5.3 Display Control

The switcher supports CEC, and the DISPLAY CONTROL buttons on the front panel are designed for Display On/Off and volume adjustment.

• ON: Display On.
- OFF: Display Off.
- mute/unmute display audio.

Press RES button repeatedly to set the VGA resolution to 1280x720, 1920x1080 or 1920x1200, and its corresponding LED will illuminates green.

5.5 EDID Setting

The Extended Display Identification Data (EDID) is used for the source device to match its video resolution with the connected display. By default, the source device obtains its EDID from the first connected display. Meanwhile, since the displays with different capabilities are connected to the switcher, the 4-pin DIP switch on the rear panel can be used to set the EDID to a built-in fixed value. Use the following table to determine the setting for the 4-pin DIP switch for specific video resolution and audio capabilities.

The switch represents "0" when in the lower (OFF) position, and it represents "1" while putting the switch in the upper (ON) position.
