5. Display goes to sleep - Power Saving and No Signal on the Mac

Modified on Sun, 03 Mar 2024 at 09:51 AM

Display Setup on the Mac

This means that the controller receives power but not video signal, and when there is no video signal it goes to sleep, displaying the "No Signal" message.

First check that connect it to the Display port, either with USB-C to USB-C or USB-A and HDMI.

Note: The "Display additional power" port will not transfer video signal when connected and it should only be used to provide additional power. If you connect only this port, the display of the controller will go into power saving and display the "No Signal" message

See the connection diagrams on the initial setup guide.

When you connect the Display port and the MP MIDI logo comes on, before it goes to Power Saving mode, use the remote control to select the correct input, HDMI or USB-C

If all the above is ok, and you steel don't get video signal to the monitor, check that the resolution and Refresh Rate on the Mac is set correctly.

The resolution of the monitor should be set to 1920 x 1080, if not set automatically by the OS.

Set the monitor as external display in Displays on the Mac. (not mirror)

The monitor frequency should be automatically set to 60Hz. 

In some cases, the Mac OS may set it to 75Hz and this will cause the display to not be able to show any video. The refresh rate settings on MacOS are hidden — In Display Settings, be sure to hold the Option key when clicking "Scaled" to see the refresh rate option.

See video how to change the refresh rate on MacOS Sonoma
