Using Display Switch

The function Display Switch has been extended with IGEL OS 11.01.100. It is now possible to use several different profiles, which are automatically selected at runtime depending on the currently connected monitors.
A profile is created when the current monitor layout, or the current resolution, is configured via Display Switch. The profile is automatically assigned to the currently connected monitors and recognizes the manufacturer, model by plug and, if available, the status of the laptop cover. When the screen configuration changes (by hot (un)plugging), the system will automatically switch to the profile.
The Display Switch function has been redesigned in IGEL OS 11.01.100 with a new graphical user interface. All basic functions can be configured by drag-and-drop.

->Start the Display Switch function. The start options are described under Display Switch Configuration.

Identify Displays

->To start screen detection, click on Identify Displays
The names and properties of the screens will be detected. The connection, the assigned number (1 = main screen) and the name will be shown on each screen. Example: 1: DVI-D(II): Samsung 24"

Defining Main Screen

1. If necessary, switch to the advanced dialog with Advanced.

2. Select the screen that you wish to define as the main screen.

3. Set the Index to 1.
   The display is now marked as the main screen.

Split Display over Several Screens

You have various options for using several screens. In the dialog, the connection, the assigned number (1 = main screen) and the name is shown for each screen. Example: 1: DVI-D(II): Samsung 24"

The procedure with the minimal dialog is described below. To switch from the advanced to the minimal dialog, click on Simple.

->To show the same content on all screens (Shadow screens), click on 

->If you would like to expand the display to all screens and the other screens are to the left of the main screen, click on

->If you would like to expand the display to all screens and the other screens are to the right of the main screen, click on

From IGEL OS 11.01.100, a drag-and-drop interface is available for individual customization. Click Advanced to show the drag-and-drop interface:

->Use drag-and-drop to move the displays to the desired configuration. They will snap together when they touch each other at the edge.

->If you no longer need a monitor, in Advanced mode you can simply drag it to the upper right corner to the Disabled area to disable it.   To display the same content on multiple displays, drag them one on top the other. Mirror \<other> will be displayed. The mirroring monitor is displayed in the lower right corner.

->Click Apply to set the current status. Click Yes in the Keep Configuration window to save the configuration permanently and associate it with the profile.

Rotate Displays (Page Orientation)

The procedure with the minimal dialog is described below; Setup > Accessories > Display Switch > Options > Rotate displays (Page orientation) must be enabled. To switch from the advanced to the minimal dialog, click on Basic.

->To rotate the display counterclockwise, click on

->To rotate the display clockwise, click on 

Change Mouse Settings

The procedure with the minimal dialog is described below; Setup > Accessories > Display Switch > Options > Mouse Options must be enabled. To switch from the advanced to the minimal dialog, click on Simple.

->To adjust the mouse for left-handed users, enable the Lefthanded Mode.

->To adjust the speed of the mouse pointer, change the value under Pointer speed. The higher the value, the further the mouse pointer will move when the mouse is moved.

->To change the time interval within which two consecutive mouse clicks are recognized as a double-click, change the number of milliseconds under Double click interval.

Zoom Display (Screen Magnifying Glass)

You can magnify the screen content. The effect is the same as with the screen magnifying glass in Microsoft Windows: All text and graphics are magnified by the same factor; this results in a virtual display area which is bigger than the monitor’s available display area. The user therefore sees a magnified section of the entire screen; the section can be moved by moving the mouse to the edge of the screen.

1. If necessary, switch to the advanced dialog with Advanced.

2. Under Panning, set the desired value. Example: 3860x2160

3. Under Resolution, set a low value. This value simulates the actual resolution of the screen. Example: 1280x800

4. Click on Apply.
   The screen content will be magnified. The magnification factor results from the ratio of the virtual resolution and the simulated actual resolution.

   

   If the same content is displayed on a number of screens (Shadow screens), all screens will show the same section. However, you can set a different magnification level for each of the screens.

   
   

Change Refresh Rate

This is only possible if a resolution has been selected. The respective resolutions can be different. A refresh rate of 60 Hz is usually suitable for standard screens.

1. If necessary, switch to the advanced dialog with Advanced.

2. Under Refresh rate, set the desired value.

Restore Default Settings

->Click on Reset to restore the default settings.
