1284 Built-in HDMI Port May Go Offline on macOS After SleepApr-28-26
When a Mac is started with the dock already connected, the dock’s built-in HDMI port may go offline after the Mac wakes from sleep. If this occurs, the HDMI display may not be detected again until the dock is power cycled.
Workarounds / Recommendations to help prevent this issue:
• Connect the dock after the Mac has finished booting. Disconnect the dock before restarting the Mac or installing macOS system software updates.
• Use display sleep instead of computer sleep. For example, set a Hot Corner to put the display to sleep rather than allowing the Mac itself to enter sleep.
• Use a Thunderbolt-to-HDMI adapter instead of the dock’s built-in HDMI port. Connect the adapter to one of the dock’s Thunderbolt ports.
