On this page
From the portal, you can reload a display's content, take a screenshot, make the display light up so you can find it, or switch the TV off and on. A restart always affects the whole device.
Steps
- Open Displays, choose the display, and switch to the Diagnostics tab.
- Under This display, choose an action. Each one says in a line what it does.
- Watch the status of the command. It moves from sent to accepted to done.
| Action | What it does |
|---|---|
| Reload content | Loads the display's content again. The picture turns white for about two seconds. |
| Screenshot | Takes a picture of what the display shows right now. |
| Identify | Makes the display light up for a few seconds so you can find it on site. |
| Screen off and Screen on | Puts the TV on standby or wakes it up again. The device keeps running. |
Under The device behind it, you find Restart, Fetch log, and Check for updates. They affect the whole device and every display on it, see Maintain a device remotely: restart, log, update.
An action appears only if the device supports it. A web display, for example, takes screenshots only with the display extension and can't switch the TV off.
Check the result
Below the actions, Commands lists the latest commands for this display and its device. A screenshot opens with View.
If something goes wrong
| Symptom | Cause | Solution |
|---|---|---|
| The device isn't reporting right now | The device is offline. | Commands wait and run as soon as the device reports again. If that takes too long, they expire. |
| no answer | The device didn't respond in time. | Check whether the device is reporting, then send the command again. |
| An action is missing | The device or the TV doesn't support it. | For switching the TV, see Set up the TV for all-day use. |
| The actions are grayed out | Your role doesn't allow commands. | Ask someone with the Owner or Manager role. |
