It looks like it's not a good idea to use a HDMI switch with MorphOS. Theis seems to be the problem. After switching the input source and than switching back to MorphOS the screen is black.
If you search on the internet for "hdmi switcher" and "black screen", you will find plenty of people with Windows PCs, Macs or even Playstation consoles who have run into similar issues.
Switchers are often hit or miss, I am afraid. I hope you did not spend too much on it.
Does your monitor only have a single input port? The last time I saw a display with less than two ports must have been more than 10 years ago.
