Hi @Arjan,
Thanks for reporting this and for sharing the video.
This looks like it may be related to the display calibration setting. Could you try changing the display calibration mode?
To access Display Calibration:
Go to the Settings page
Press and hold FX + SELECT
While holding them, the first 3 grid pads will show the available display calibration options
Try the different options and see if one of them resolves the blank screen behavior
The display will briefly power cycle when selecting a mode, which is expected.
You can also find the details in the manual here
I hope this helps but please let us know how it goes, and if the issue persists after trying the calibration options we’ll take the next step from there.
