DisplayLink screens are not available at the first login screen when FileVault is enabled. (21278) Protected content from iTunes and other players is not visible on built-in graphics when DisplayLink screens are connected. (17087) The list of available resolutions and the default resolution for 4K displays depends on the type of connection (HDMI or DisplayPort). To see a more complete list of resolutions follow these steps: - Open the Displays preference in System Preferences - Go to the preferences panel for the DisplayLink screen - While keeping the option (alt) key pressed, select the "Scaled" option for the list of resolutions. The internal screen is kept active while in clamshell mode on OSX systems with a single HD3000 graphics card. Manual Ethernet speed setting is not retained across reboots. (20973) H. Common recovery steps ======================== An updated list of troubleshooting suggestions is available at http://support.displaylink.com/knowledgebase/ Most of the issues can be resolved by replugging the DisplayLink device which exhibits the problem. In very rare cases, the recovery requires rebooting. If macOS cannot boot correctly after the DisplayLink software installation or after a system update: - Restart the system and perform a safe boot by keeping the shift key pressed during the startup sequence (it will take longer than usual) - Use the uninstaller to remove the whole DisplayLink software or remove the DisplayLinkDriver.kext file from /Library/Extensions, then restart the system I. Known issues and limitations =============================== Not all display modes are available for rotated DisplayLink screens. (13464) Retina resolutions on DisplayLink screens may result in reduced performance. For higher performance use the screen at its native resolution. (21314) Screen corruption while mirroring multiple DisplayLink screens. (15633, 16121, 17077) Some color calibration applications may not be able to affect DisplayLink screens. Some options in the Accessibility system preference have no effect on DisplayLink screens, for example “Invert colours” and contrast settings. Some advanced DL-41xx features are not supported on the macOS platform: On Screen Display, splash screen and connection status feedback.
