There are several possible reasons for black screens:
- A wrong input channel is set (e.g. HDMI2 instead of HDMI1)
- A display timer is set (e.g. it's 8 am but the timer for the screen to be switched on is set for 9 am). Please take care that you are using the right time zone in your settings.
- The viewneo Signage Stick is connected via USB to the screen. If the screen has been switched off by a display timer, viewneo will switch off the signage stick as well and can only be put back in operation through a manual switch-on.
