Every screen connected to the IGEL UD device can be configured independently. The position of the individual screens can be determined in relation to Screen 1.

Click on Info to show the screen identifier on each device.

For details of the display resolution supported by your IGEL device, please see the relevant datasheet.

If you work in an environment with a number of monitors, see the how-to Multimonitor.

If you use the Shared Workplace (SWP) feature with user-specific display resolutions, see the how-to Display Configuration for Shared Workplace (SWP).

Screen selection

The selected screen is highlighted with a blue frame. The black bar at the bottom edge of the screen represents the physical orientation of the monitor.

Selected screen: Selects a screen using this selection box to configure the following settings.

Screen resolution: Move the slider to the resolution which the selected screen is to have. The resolution is shown in the right-hand box.

From IGEL Linux Version 10.03.100, you have the option of defining your own resolutions via the registry (x.xserver0.custom_resolution). In order for the values set there to take effect, the resolution must be set to "Automatic" (slider at the far left). The following parameters apply to the entry in the registry:
  • WxH : W = width, H = height (example: 1920x1080)
  • WxH@R : W = width, H = height, R = refresh rate (example: 1920x1080@60 or 1920x1200@59.8)


Detect refresh rate automatically
☑ A refresh rate for the monitor is identified automatically. (Dafault)
☐ A refresh rate for the monitor is to be set manually.

Refresh rate: Number of individual images per second.
Possible values:

  • 30 ... 100. (Default: 60)

Graphic card: Graphics card assigned to the selected screen. A graphics card can have more outputs than are actually used. In order to ensure transparency, you may need to assign the graphics cards manually.

If Automatic is set for the Monitor and no configurable monitor is found for the selected graphics card, the next available monitor will be used by another graphics card.

Monitor: Assigns the screen selected under Selected screen to a monitor connection. Example: HDMI(II). (Default: Automatic)
