Display Editor

Displays define the resolution and pixel coordinates of media sources on the output canvas of the media server.

The Display Editor allows to add new displays, set the display dimensions and positions, create display arrays, swap displays, and adjust display settings. It is accessed in the Display Editor tab of the Screenberry Panel.

An example of a basic media playback pipeline and its view in the Display Editor:

1. Media Player playback (from the MediaPlayer1 node) is sent to

2. the Display (the Display1 node) which is set to 1024 x 768 pixels and positioned by default at (0,0) coordinates of

3. server output area defined as the context area (the Context1 node) which is set to 1920 x 1080 pixels.

Adding a Display

To add a new display in the Display Editor tab:

  1. Select the context area in the Root/Context dropdown menu.
  2. Click the Add Display button.
  3. Enter a new display name in the opened dialog box and press OK.

By default, the resolution of the added display will be equal to the context resolution.

The corresponding Display node will be created in the Node Graph and linked to the Context node of the selected context area.

Reversely, a new display can be added by adding a new Display node in the Node Graph and linking it to the Context node of the relevant context area.

Creating a Display Array

A display array allows you to split the video output into a set of virtual displays with identical dimensions where every display can define the resolution and pixel coordinates of an individual video card output (or video device).

To create a display array:

  1. Select the context area in the Root/Context dropdown menu.
  2. Click the Create Display Array button.
  3. In the opened dialog box, enter the number of desired Rows and Columns for the display array, select the Patch Type to be applied to the displays and press OK.

As a result, the array of displays will be constructed to fit the context dimensions. The displays will be named 1, 2, 3, etc., arranged from left to right and top to bottom. Simultaneously, the corresponding Display nodes and related Patch nodes will be added and linked in the Node Graph.

Note:
The creation of a display array removes all the displays previously added to the current context area.

Renaming a Display

To rename a Display, right-click on the Display area, select Rename in the drop-down menu, enter a new display name in the opened dialog box and press OK.

Deleting a Display

To delete a Display: 

  • Right-click on the Display area and select Delete in the drop-down menu (or press the Del button), or
  • Delete the corresponding Display node in the Node Graph.

Disabling a Display

Disabling a Display node in the Node Graph (see Node Status) will disable the corresponding Display in the Display Editor. To indicate that a node has been disabled, the Display area will be crossed off.

Swapping Displays

To swap displays in the context area, click the Swap Displays button. In the opened dialog box:

  1. Select a display from the drop-down menu, or cycle through the displays by pressing the Skip button.
  2. With the desired display selected, enter the name of the display it has to to be swapped with in the With field and press the Apply button.

Note:
This procedure is particularly useful during the setup. There is no need to follow a particular order when connecting displays to the server, as this order can be easily changed later by employing the Swap Displays method.

Display Dimensions and Position

To define the dimensions and positioning of a Display in the context area, select the corresponding Display node in the Node Graph and change: 

  • X and Y values in the Size fields for the display resolution,
  • X and Y values in the Offset fields for the display position

in the node Settings panel (see Node Settings).

Changing the Stack Order of Displays

To change the stack order of Displays in the context area, reorder the links connecting Display nodes to the Context Node in the Node Graph (see Reordering Node Links). 

The displays are stacked top-down in relation to the order in which Display nodes are linked to the Context Node in the Node Graph, which means that a display with a succeeding node link will overlay that with a preceding one.

Turning on Display Test Pattern

To show the test pattern for a Display, select the corresponding Display node in the Node Graph, activate the Test Pattern parameter in the node Settings panel, and select the Label, Grid, Color Bars, or Gradient option in the Test Pattern dropdown menu.

Zooming and Panning in Display Editor

Тo zoom in and out a specific area in the Display Editor, move the mouse cursor to the desired location and use the mouse scroll wheel. Alternatively, click the button in the top right corner and move the mouse to the left or right to change the magnification.

To pan a view in the Display Editor, hold the mouse scroll wheel button or click the button in the top right corner and move the mouse.

 

Accessing Patches Editor for a Display

To switch to editing patches associated with a display, right-click on the Display area and select Show Patches in the drop-down menu.
