Question

Can the DIVAR network or hybrid UHD monitor setting cause black screen when UHD not supported?

Answer

Not all monitors support UHD, resulting in black screen. The local user interface does not have a recovery mechanism.

However, having network access, the value can be adapted by the web browser interface: settings -> display -> resolution

Choose a value supported by the connected monitor.
