Customizable Session Features

The following PCoIP session features can be customized:

  • Session Menu Bar Visibility
  • Disable Hot Keys
  • Windowed or Fullscreen Mode
  • Set Host Resolution
  • Image Scaling
  • Maintain Aspect Ratio

Examples show command-line usage

The examples shown here invoke the PCoIP Software Client via the command line. You can also set these priorities when invoking the PCoIP Software Client programmatically.

Session Menu Bar Visibility

To enhance the user experience the PCoIP Session Client enables the menu bar by default, however some use cases may require that it be disabled, or hidden, in order to prevent the user from accessing menu functionality. To disable the menu bar feature use the parameter disable-menubar.

Disable Hot Keys

To improve usability, session hot keys, such as Ctrl+Delete+F12 (which disconnects a PCoIP session) are available to users by default. The parameter for this feature is disable-hotkeys.

Windowed or Fullscreen Mode

Depending on your application needs, you can display the PCoIP session in either windowed or fullscreen mode. Fullscreen mode allows the display topology to support multiple monitors as an extended desktop; windowed mode gives you the flexibility to display multiple application windows in parallel and switch between them quickly. Windowed mode improves the user experience, as well as resulting in an increase in performance. Windowed mode is the default mode, and to activate fullscreen mode use the full-screen parameter.

Set Host Resolution

Normally, the session client opens with arbitrary window dimensions. In some cases, you may wish to lock the resolution of your host application displays. This ensures the user’s viewing experience is consistent across different monitors and their native resolutions. The parameter for this feature is set-host-resolution.

  • Host Resolution Limitations: It is only possible to specify one target resolution for all displays. The host resolution will not perform to its optimal capability if you have monitors with different resolutions.

Image Scaling

The image scaling feature enables scaling on the client without having to specify the desktop resolution. You can apply image scaling when the resolution of the client monitor is not the same as the resolution provided by the host. This feature provides a smoother process for image scaling on the client. The parameter for this feature is enable-scaling.

Maintain Aspect Ratio

If the host and client aspect ratios do not match, and this parameter is not used then the display will be stretched to fit. The parameter for this feature is maintain-aspect-ratio. If the native aspect ratios of the host’s display and the client’s display do not match, the host’s aspect ratio will be preserved and will appear in the client with black bars either on the sides or top and bottom of the display.

PCoIP Client Keyboard Handling

When the PCoIP Software Client for macOS is the foreground application it will capture system level keyboard shortcuts such as CMD+TAB and CMD+SPACE and send them to the remote machine. This is enabled by default with the mac_system_shortcut_capture OS setting. These shortcuts will no longer be actioned on the local machine when the PCoIP Software Client for macOS is in focus. The CMD key will no longer be mapped to the CTRL key even if the remap_cmd_to_ctrl setting is enabled. You will need to enable accessibility permissions on the PCoIP Client in order for the keyboard to function with these changes. Instructions for how to enable these permissions are outlined below.

The mac_capture_all_keys setting captures all keys and modifiers on the PCoIP Software Client system when the PCoIP Software Client for macOS is in focus, except for the Fn keys when they are enabling special functions, such as keyboard brightness, volume, etc. This setting is enabled by default.

The remap_cmd_to_ctrl setting is a pre-existing setting which controlled whether the command key would map to Control, or the Windows (Super on Linux) key. This setting is disabled by default. It can be enabled if necessary by first disabling the mac_system_shortcut_capture and mac_capture_all_keys setting.

Enabling Accessibility Permissions for PCoIP Client

The keyboard handling of the PCoIP Client for macOS has be updated to handle new default handling for the CMD key to capture and send to remote systems. In order for this new keyboard handling to function, the PCoIP Client application must be authorized under System Preferences > Security & Privacy > Accessibility, not authorizing the application will result in the Keyboard not functioning in a PCoIP session.

When the PCoIP Client is opened for the first time on a Mac it should prompt the user to authorize the Accessibility permission. This requires the user to accept the prompt and enter the password. If this is declined, the prompt will not appear again and the Accessibility permission must be configured manually from within System Preferences.

The following steps outline how to manually set the accessibility permission:

  1. Open System Preferences.
  2. Click on Security & Privacy.
  3. Select the Privacy tab.
  4. Select the Accessibility option.
  5. Click the Lock icon on the bottom left corner and authenticate using your password or touch ID.
  6. Click the check mark beside PCoIP Client as outlined in the image below.
