PICTURE ID Settings

PICTURE ID is used to change the settings of a

specific set (display) using a single IR receiver for multi-vision. Communication is possible between a monitor with an IR receiver and other monitors using RS-232C cables. Each monitor is identified by a Set ID. If you assign the PICTURE ID using the remote control, only displays with matching PICTURE ID and Set ID can be controlled remotely.

1 Assign the Set ID to the installed monitors

as shown below.

IR & Light Sensor

RS-232C cables

PICTURE ID ON [2]

3 Assign the Set ID to the selection of your

choice.

• A set with a different Set ID from the

PICTURE ID cannot be controlled by IR signals.

NOTE

• If PICTURE ID is set to 2, only the upper

right monitor, which has a Set ID of 2, can be controlled by IR signals.

• If you press the green OFF button for

PICTURE ID, the PICTURE IDs for all monitors are turned off. If you then press any button on the remote control, all monitors can be controlled by IR signals regardless of Set ID.

• With PICTURE ID ON, you can only

increase the PICTURE ID by 1. You cannot decrease it.

2 Press the red ON button on the remote

control to assign the PICTURE ID.

modem. After connecting the display to the home network, quickly power off and/or disconnect the power cable of the home network router or cable modem, then power on and/or connect the power cable again.

• Depending on the Internet Service Provider (ISP), the number of devices that can receive Internet

service may be limited by the applicable terms of service. For details, contact your ISP.

• LG is not responsible for any malfunction of the display and/or the Internet connection feature due

to communication errors/malfunctions associated with your Internet connection, or other connected equipment.

• LG is not responsible for problems with your Internet connection.

• You may experience undesired results if the network connection speed does not meet the

requirements of the content being accessed.

Tips for Wireless Network Setting

• Wireless networks can be subject to interference from other devices operating at a frequency of 2.4

GHz (wireless phones, Bluetooth devices or microwave ovens). There may also be interference from devices with a frequency of 5 GHz, same as other Wi-Fi devices.

• The surrounding wireless environment can cause the wireless network service to run slowly.

• If you do not turn off the entire local home network, network traffic may occur on some devices.

• For an AP connection, an access point device that supports wireless connection is required and the

wireless connection feature must be enabled on the device. Contact your service provider regarding availability of wireless connection on your access point.

• Check the SSID and security settings of the AP for AP connection. Refer to the appropriate

documentation for SSID and security settings of the AP.

• Invalid settings on network devices (wired/wireless line sharer, hub) can cause the monitor to run

slowly or not operate properly. Install the devices correctly according to the appropriate manual and set the network.

• Connection method may differ according to the AP manufacturer.

What is image sticking?

When the LCD panel displays a static image

CFCFCF

for an extended period of time, it can cause a voltage difference between the electrodes that operate the liquid crystals. When the voltage difference between the electrodes builds up over time, liquid crystals have a tendency to remain aligned in one direction. During this process, a previously displayed image remains visible. This phenomenon is referred to as image sticking.

NOTE

• PC resolutions available for the Input Label

option in HDMI(OPS) / DVI / DISPLAYPORT input modes: 640 x 480/60 Hz, 1280 x 720/60 Hz, 1920 x 1080/60 Hz; 480p, 720p, and 1080p DTV resolutions.

NOTE

• Vertical frequency: The product display

functions by the screen image changing dozens of times every second like a fluorescent lamp. The vertical frequency or refresh rate is the number of image displays per second. The unit is Hz.

• Horizontal frequency: The horizontal interval

is the time taken to display one horizontal line. When 1 is divided by the horizontal interval, the number of horizontal lines displayed every second can be tabulated as the horizontal frequency. The unit is kHz.

Transmission/Reception Protocol

Transmission

[Command1][Command2][ ][Set ID][ ][Data][Cr]

* [Command1]: identifies between the factory setting and the user setting modes.

* [Command2]: controls monitor sets.

* [Set ID]: Used for selecting a set you want to control. A unique Set ID can be assigned to each set

ranging from 1 to 1000(01H~3E8H) under Settings in the OSD menu.

Selecting '00H' for Set ID allows the simultaneous control of all connected monitors.

* [Data]: Transmits command data.

Data count may increase depending on the command.

* [Cr]: Carriage Return. Corresponds to '0x0D' in ASCII code.

* [ ]: White Space. Corresponds to '0x20' in ASCII code.

Acknowledgement

[Command2][ ][Set ID][ ][OK/NG][Data][x]

* The Product transmits ACK (acknowledgement) based on this format when receiving normal data. At this time, if the data is FF, it indicates the present status data. If the data is in data write mode, it returns the data of the PC computer.

* If a command is sent with Set ID '00' (=0x00), the data is reflected to all monitor sets and each monitor set does not send an acknowledgement (ACK).

* If the data value 'FF' is sent in control mode via RS-232C, the current setting value of a function can be checked (only for some functions).

*Some commands are not supported depending on the model.
