Here's what I would do to troubleshoot: Try disconnecting then reconnecting all the HDMI cables to the switch box. If that doesn't work, turn off / unplug the switch box for about 10 seconds and turn it on / plug it back in. If that doesn't work, then I'm not sure.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
