Extended control for LG webOS
LG webOS displays expose their panel settings through the LG SCAP and IDCAP APIs. Box drives both from the Extended control tab, so a display can be brought to a known-good state without anyone visiting it.
The tab picks the right API for the display automatically: webOS 6.0 and newer use IDCAP, older versions use SCAP. You do not choose between them.

One action applies the settings signageOS recommends for a production display. The card lists every setting and the value it writes before you run anything.
| Setting | Value | Why |
|---|---|---|
| Wake-on-LAN | Enabled | The display can be woken over the network. |
| Wake-on-Wireless-LAN | Enabled | Same over Wi-Fi. Panels without a wireless module skip this. |
| Power saving | Off | Turns off smart energy saving, DPM, automatic standby and the 15-minute no-signal power off, so the screen does not dim or shut itself down. |
| Tile mode | Off | A stray tile configuration crops the picture on a single screen. Panels without tile support skip this. |
| Failover mode | Off | The display stays on the signageOS input instead of switching away when it thinks the signal is gone. |
| Power-on status | Power on | After a power cut, the display comes back on by itself rather than into standby. |
| Power management mode | Network ready | The network stays reachable while the display is off, which is what makes remote wake and monitoring work. |
Select Deploy configuration, confirm, and the run starts on the display. When it finishes, each row gets its own result:
- Applied — the display accepted the setting.
- Failed — the display rejected it, with its own error message next to the row.
- Skipped — the model does not have the hardware for an optional setting, such as wireless wake on a wired-only panel.
The full log of the run is available under Script output for support cases, and the run is recorded in the device's script history.
Tile mode
Video wall layout, set remotely. Use it to build a wall, correct a single misconfigured screen in an existing one, or turn tiling off.
| Field | Meaning |
|---|---|
| Status | Whether tiling is on or off. |
| Rows / Columns | The size of the wall, for example 3 by 3. |
| Tile ID | The position of this display inside the wall. |
| Natural mode | Compensates for the bezels so the picture continues across the gap between panels. |
Values from the last run are pre-filled, so fixing one screen in a wall is usually a two-field edit. After the run, Box shows the layout the display accepted, or, when the panel refused it, the layout that was attempted together with the error.
The current layout cannot be read back from the panel — LG displays do not report it. Box therefore shows the result of the last run made from Box, not live panel state. A layout changed with the physical remote will not appear here.
