ControlSync simultaneously controls all sub-monitors connected to a master monitor. It can also individually control a single submonitor using the INDIVIDUAL ADJUST function (see page 21). Controlling all connected sub-monitors (Synchronized control): • Connect a ControlSync cable (ø 2.5) to the master monitor’s ControlSync OUT port and into a sub-monitor’s ControlSync IN port.
The following settings can be controlled by ControlSync: ECO TOOLS SCREEN COLOR TOOLS MENU TOOLS MULTI DISPLAY ECO INFORMATION BRIGHTNESS* CONTRAST ECO MODE AUTO BRIGHTNESS BLACK LEVEL OFF MODE SETTING OFF MODE SENSOR SETTING OFF MODE START TIME HUMAN SENSING HUMAN SENSOR SETTING HUMAN SENSOR START TIME DV MODE LEFT/RIGHT DOWN/UP H.RESOLUTION V.
OSD (On-Screen Display) control keys on the front of the monitor function as follows: 1 Ambient Light Sensor Human Sensor Detects the level of ambient lighting and the presence of a user, allowing the monitor to make adjustments to various settings resulting in a more comfortable viewing experience. Do not cover this sensor. 2 INPUT/SELECT Changes the input source when the OSD menu is closed. Enters a sub-menu when the OSD menu is open.
ECO TOOLS BRIGHTNESS Adjusts the overall image and background screen brightness. If ECO MODE is set to 1 or 2, a bar for CARBON FOOTPRINT will appear. CONTRAST Adjusts the overall image and background screen brightness by input signal level. NOTE: CONTRAST and DV MODE can be adjusted for all COLOR CONTROLS except L/B. ECO MODE Decreases the amount of power consumption by reducing the brightness level. OFF: Does not function. 1: Sets the brightness variable range from 0% to 70%.
The sensor detects the movement of a person by using the HUMAN SENSING function. The HUMAN SENSING function has three settings: OFF: Does not function. 1 (LIGHT): After it detects that there is no person after a period of time, the monitor shifts to low brightness mode automatically to reduce the power consumption. When a person comes near the monitor again, the monitor will automatically return to normal mode. START TIME adjusts the wait time before entering the low brightness mode.
OVER SCAN (HDMI input only) Some video formats may require different scanning modes in order to best display the image. ON: Image size is larger than what can be displayed. The image edge will appear cropped. Approximately 95% of the image will be shown on the screen. OFF: Image size stays within the display area. The whole image is displayed on the screen. EXPANSION Sets the Zoom method. FULL: The image is expanded to full screen regardless of the resolution.
English Tools VOLUME Controls the volume of the speakers or headphones. To mute the speaker output touch the “ /RESET” key. SOUND INPUT Selects audio source.
