how to wake up mac monitor from sleeping

As soon as I unplug the HDMI cable from the adapter, the laptop recognizes that the display is gone and goes back to single monitor mode, and all my windows jump to the laptop screen.

So normally I unplug the HDMI cable between the adapter and the KVM switch.

I can switch off or unplug either the KVM switch or the CalDigit dock, but those also affect other computers or peripherals. I have to disconnect or power-cycle something to get the video to reset. But, power-cycling the monitor does not fix it. Plugable answer your last question first, I can switch off just about any part of the signal chain and the display will wake up. When the display is not detected, does unplugging and reconnecting the docking station to the computer also restore the display connectivity? Similarly, does disconnecting then reconnecting the KVM switch also restore the display? We can start by verifying if only disconnecting and reconnecting the DisplayPort to HDMI adapter resolves the issue or if the other devices in the display connection path could also be interfering with the connection. Thanks for reaching out to us, I am sorry this is not working as expected and I am happy to help!ĭisplay detection on wake from sleep with macOS can be a bit tricky, we see this come up with both our DisplayPort to HDMI adapter as well as with other USB-C graphics adapters and even with natively connected displays.Ībout how often does the display fail to detect on wake from sleep, for example is it about every other wake even or only after the laptop has been asleep for overnight?Īll of our DisplayPort to HDMI adapters purchased from Amaozn within the last 2 years will already have the updated firmware, if you have an older adapter please let me know and we can definitely try the firmware update.
