Device settings reference
Each device has settings that control how it displays content, its audio, network, and more. Open a device and edit its settings. This page is split into everyday settings (safe to change anytime) and advanced settings (need extra care)
Golden rule: always start from the device's current settings and change only the field you mean to — leave everything else as-is. Then verify on the screen (a screenshot confirms the result — see Managing devices day-to-day).
Everyday settings
Open a device's settings
Open the device list from the right edge of the dashboard.
On the device's card, click the settings icon (⚙) — Show device settings.
The Device Settings window opens. Its header shows the device identifier, the device ID, the IP address and the app version the screen is currently running.
The settings are grouped into tabs — Device, Network, Emergency, Services, Inference — with Advanced Settings on the right. Everything in this section is on the Device tab.
Change what you need, then save at the bottom of the window.
The Device Settings window, Device tab: the Audio and Display sections
Set the volume, or silence a screen
Open the device's settings and stay on the Device tab.
In the Audio section, set Volume — drag the slider, or type a number from 0 to 100 in the box beside it.
Save.
To silence a screen you have two choices in this window: set Volume to 0, or switch Enable Audio off. Enable Audio off silences the device whatever the volume says; volume 0 leaves audio switched on but at zero.
Audio settings
For a quick, one-off change you don't need this window at all — use the volume button on the device's card, or simply ask the assistant. See Turn a screen on or off, mute it, set volume and Send a command to a screen.
Rotate the screen (orientation)
Open the device's settings and stay on the Device tab.
In the Display section, find Orientation and click the option that matches how the screen is physically mounted:
Landscape 0° — normal, horizontal.
Portrait 90° — turned a quarter turn.
Flip 180° — upside down, typical for a ceiling mount.
Portrait Flip 270° — portrait, turned the other way.
Save. The player redraws itself in the new orientation.
Display orientation & resolution
Two things to keep in mind. Your content should be the same shape as the orientation you choose — a portrait screen needs portrait content. And on managed impressBox players, low-level display changes such as rotation and resolution are locked by default; see Custom resolution, width & height.
Brightness
A screen's brightness is set in one of three ways. If more than one is active, the screen uses them in this priority order:
Automatic (astronomical) — if turned on, it decides the brightness from the sun.
A scheduled brightness item — if a schedule is currently telling the screen a brightness.
Manual brightness — your fixed value, used when neither of the above is active.
Manual brightness
Set a single fixed brightness — the Brightness value (0–100), where 0 is darkest and 100 is brightest. The screen holds it until you change it. This works on all supported screens right now.
To set it: open the device's settings, scroll down, find the Brightness section and set Backlight, then save. You can also just ask the assistant, e.g. "Set device Lobby brightness to 50%."
Brightness (Simple)
Automatic brightness — sunrise & sunset (astronomical)
Turn this on and the screen manages its own brightness all day: dim at night, bright by day, smooth in between — no daily clicking. It works out local sunrise and sunset from the current time and the device's location.
Availability: automatic brightness activates with the latest player version. If you switch it on and nothing changes, the screen is most likely still on an older player — it will start working once the device updates. Until then, use manual brightness above.
Before you start: the device must have a location (latitude/longitude) set, or it can't calculate sunrise/sunset. Set the location first.
Turn it on:
Open the device's settings.
Scroll down to the Brightness section. Select Advanced.
Brightness → Advanced
Switch Astronomical Brightness on.
Enable Astronomical Brightness
Fill in the values below and Save.
Astronomical brightness values
Setting | What it means | A safe starting point |
|---|---|---|
Min Brightness (night) | How dim at night, 0–100 |
|
Max Brightness (day) | How bright in daylight, 0–100 |
|
Sunrise Offset (min) | Shift the morning change; + = later |
|
Sunset Offset (min) | Shift the evening change; + = stays bright longer after sunset |
|
Recalculation Interval (sec) | How often it re-checks and adjusts |
|
What you'll see through the day: deep night → Min; dawn→sunrise → gradually up to Max; full day → Max; sunset→dusk → gradually down to Min; night → Min again.
Tips:
Right after sunset it's often still bright outside, so set the Sunset Offset to 30–60 min to keep the screen bright a little longer.
While automatic brightness is on, it overrides your manual value (per the priority list above) until you switch it off.
Far-north/south locations are handled: on days when the sun doesn't truly rise or set, the screen simply uses Max while the sun is up and Min while it's down.
If it dims too early in the evening, increase the Sunset Offset. If it's too dark at night, raise Min Brightness.
How the screen actually dims: on screens with hardware brightness control (e.g. LG/webOS, many Android) the panel itself dims; on others the player darkens the picture with a soft black layer — the result looks the same to a viewer.
The other tabs
Everything above is on the Device tab. The rest of the window has its own topics, each covered on its own page:
Network — set the device's network and IP address, on screen models that support it. See Network & IP addresses in manage.
Inference — camera analytics, where that applies. See AI inference (camera analytics).
Advanced Settings — low-level display options: a hardware-unlock safety switch, and custom resolution / fullscreen for unusual panels (bars, totems, tiled walls). Standard screens never need these, and a wrong value can leave a screen blank. See Custom resolution, width & height.
The Emergency and Services tabs are used during setup and integration work rather than day-to-day — your impressBox contact will tell you if you ever need them.
Safe-change checklist
Read the device's current settings first.
Change only what you need; keep the rest of the structure as-is.
For low-level display changes (custom resolution, rotation on managed players) follow the extra steps on Custom resolution, width & height.
Save, then verify on the screen — a screenshot confirms the result.
