Device wall & groups

The device wall is VMOS Cast's main screen: the live view of every connected device lives here.

Basic operations

What you want to do	How
Control one device alone	Click the card's screen area to open a standalone control window
Select/deselect a device	Click the area outside the screen on the card (title, edges)
Select all visible devices	"Select all" in the toolbar
Invert visible devices	"Invert" in the toolbar
Resize cards	The Size slider on the right of the top status row
Search devices	The search box at the top, filter by model or IP
Filter by status	The Status dropdown at the top: Online, Connecting, Screen off, Not castable, Failed, Offline — each with a live count
Change how screens fit	The Scale dropdown at the top: Cover, Contain, or Fit Width
Rename, view details, restart / power off	Right-click a card
Remove selected devices	Expand "Batch" and click "Remove selected"

Selected devices get a blue highlighted border, and the top status row shows "N selected."

The top toolbar follows the selected state. Batch operations live on the left, while the slider on the right controls card size and column count:

Group management

Once you have a lot of devices, manage them with groups — for example "Test units," "Streaming accounts," or "Zone A":

1. First select several devices on the wall;
2. Click "New group" in the sidebar and enter a name — the currently selected devices go into that group;
3. Click a group name in the sidebar to view only that group's devices; "All" returns to the full view;
4. Expand "Batch" and use "Move to Group" to move selected devices into an existing group;
5. The count next to a group shows its device count in real time; delete a group when you no longer need it (this doesn't affect the devices themselves).

TIP

Switching groups only "filters the display" — it doesn't disconnect the other devices, so their screens are visible again the moment you switch back.

Dark mode

Pick light, dark, or follow system under Settings → Theme mode. Dark mode is easier on the eyes during long viewing sessions:

Status indicators

• The dot at the bottom of the sidebar: green = the casting service is fine; red = the service has a problem (it recovers automatically; if it stays red for a long time, restart the client);
• The platform icon in front of a device name tells Android devices apart from iPhones;
• Card states: Connecting (the screen channel is being established), Failed, Connection timed out (no picture after repeated retries — reopen the device), Screen is off, Restricted by system security, and Device offline.

Large-screen tips

• When there are many devices, narrow the view with groups before selecting all and running batch operations;
• When one device needs attention, open its control window instead of enlarging the wall cards;
• For long monitoring sessions, dark mode is easier on the eyes; switch back to light mode when capturing screenshots for support;
• To watch and drive a whole group inside one window, use Multi-view in the top toolbar.
