Set up LG TVs and LG panels (webOS)

A retail LG TV shows your display software with the Szenera Display app or in its browser. A professional LG panel opens it by itself at power-on. This page explains which of the three ways fits your device, how to set it up, and what does not work by itself afterward.

Three ways onto an LG display#

Caution: The Szenera Display app is built but is not yet in the LG Content Store. Until it appears there, use the browser route on a retail TV. Ask Szenera support about the status.

You can tell whether a device is a retail TV or a panel in the settings: A panel has a mode that opens a web address at power-on (depending on the version Simple Web Launcher, Web Browser as the start source, or SI Server). A retail TV does not have it.

With the Szenera Display app#

1. On the TV, open the LG Content Store and search for Szenera Display.
2. Choose Install.
3. Open the app. It loads the display software and, after a few seconds, shows a six-digit pairing code.
4. Sign in to the portal on a computer and choose Displays › Pair display.
5. Type in the code. The TV then shows your program.

If the app has lost its storage, for example after the TV was reset, it shows a new code. You get the existing display back without a code:

1. In the portal, on the display, choose Create a new address under Connection and lifecycle on the Device tab.
2. In the app, press OK on the remote control five times.
3. Under Connect address or its code, enter the address, or only its part from drc_ on, and choose Save.

The same field takes the address that the portal gives out when you create a web display or in the file for many displays. A TV has no address bar to paste it into, and it cannot scan it either.

The app chooses the matching display address by itself. The display software in the app updates itself from the cloud, and the app itself through the LG Content Store.

What the app can and cannot do#

A retail TV gives an app from the LG Content Store little to work with. The app tells the portal exactly that, and what does not work is missing there as a button.

The remote control in the app:

An accidental press of Back therefore does not quit the app. Whoever presses it twice in quick succession ends up in the TV’s start menu and then opens Szenera Display again by hand.

In the TV’s browser or on the panel#

Without the app, the display is a web display: The browser opens the display address and keeps it.

On the TV#

1. On the TV, open the Web Browser app and type in the display address that the portal lists under Displays › Pair display.
2. The TV shows a six-digit code. Type it into the portal.
3. Bookmark the address. After a power outage, you bring the display software back with it.

In the browser, the same limits apply as for the app, plus the address bar and menus of the browser and no automatic retry without a network. Which settings go with it on the TV is explained under Platforms: The four settings on the device.

On the panel with Web Launcher#

1. In the settings of the panel, look for the mode that opens a web address at power-on. Label and location vary between versions, but it is always the same function.
2. Enter the display address from the portal, with https:// and no trailing space.
3. Set the power-on source to this mode, otherwise the panel starts in its last source after a power outage.
4. Turn off screensaver, picture shift, and automatic shutdown, as far as the panel allows.
5. Set the on/off schedule in the panel. The display software in the browser cannot switch the panel off.
6. Pair the display as above with the code it shows.

Which address applies#

In the browser and on the panel, the browser engine of the webOS version decides, and a device usually keeps it after a firmware update:

A device with webOS 5 or 6 often shows no refusal on the display address, but a white or blank page. Then open the TV address.

Caution: This table is derived from LG’s information about the browser engine and has not yet been checked model by model on the device. The test takes a minute: Open the address, and either the display software starts or the device shows a refusal or a blank page.

On the LG panel with the app#

A professional LG panel with webOS Signage does not install the Szenera Display app from a store but from an address that you enter once at the panel, or from a USB stick. After that, the panel starts the app by itself at every power-on, without a remote control.

Caution: The app for LG panels is new and has not yet been verified on any panel. Ask Szenera support before you set up a panel in operation this way. Until then, the Web Launcher shows your display software without the app.

The app needs webOS Signage 6.0 or newer. The version is in the panel’s data sheet. Older panels cannot run the display software.

Through the SI server#

The menus have slightly different names depending on the webOS Signage version, but they always refer to the same settings.

1. With the panel’s remote control, open Settings and then Ez Setting › SI Server Setting.
2. Turn on Fully Qualified Domain Name and enter the address of the app: your TV address with /host/webos/ at the end, so https://tv.…/host/webos/. What the TV address is appears under Which address applies.
3. Set Launch Mode to Local and Application Type to IPK. Turn Auto Set off.
4. Set Local Application Upgrade to Remote and confirm.
5. Wait until the panel reports Upgrade complete. Then turn the panel off and on again.
6. The panel starts the app. After a few seconds, it shows a six-digit pairing code. Type it in on the computer in the portal under Displays › Pair display.

From the USB stick#

For a panel that has no network during setup, or for many panels with the same stick:

1. Format a USB stick with FAT32.
2. On the computer, download the app: your TV address with /host/webos/com.lg.app.signage.ipk at the end. The browser saves it as com.lg.app.signage.ipk.
3. Create a folder application on the stick and put the file in it. Do not change its name.
4. Insert the stick into the panel. Under SI Server Setting, set Launch Mode to Local, Application Type to IPK, and Local Application Upgrade to USB, and confirm.
5. After Upgrade complete, turn the panel off and on again and pair it as above with the code.

Settings for continuous operation#

Do not change the input on the panel. That quits the app until the next power-on.

What the app can and cannot do on the panel#

Your display software updates itself from the cloud. The app itself stays until you reinstall it: set Local Application Upgrade back to Remote under SI Server Setting, confirm, and turn the panel off and on again. This is rarely necessary, and Szenera support tells you when.

What is added later#

LG releases the panels’ interfaces only to its partners. With them, the app on the panel gets:

• Screenshot, restart, and on and off from the portal.
• New versions of the app without touching the panel.
• Pairing without a code with a file on the USB stick.

There is no date for this yet. A panel does not get remote maintenance with system log and service menu even then, because that exists only on a player.

Check the result#

• The display shows your program in full screen, with the app without bars and without a mouse pointer as soon as the remote control is idle.
• In the portal, the display appears under Displays. In the device record, it says webOS app with its version and Autostart blocked for the app on the TV, webOS app on an LG panel with its version on the panel, and Web display in the browser.
• Briefly unplug the network cable or turn off the Wi-Fi: The display software keeps showing what it has already loaded. With the app, the next start without a network shows a waiting page that keeps trying by itself.
