I am trying to set up a "two in - one out" mechanical HDMI switch, letting me choose between audio/video from a Roku Ultra, or a Playstation 4. The HDMI switch is manufactured by GANA and has lots of five star reviews.
I have all the latest and greatest HDMI cables.
When I configure the Roku as the single input to the switch, and the switch to output to the Visio Smart TV, everything works fine. When I do the same solo configuration with the Playstation, it works fine too.
When I connect both PS4 and Roku Ultra to the switch, I can turn on the Roku and the signal is sent to the TV. I can then switch over to PS4, turn it on, and PS4 audio/video appears on the TV.
The problem occurs when I want to return to the Roku. Once I press the button on the switch to revert to the Roku input, I get a "No Signal Detected" on the TV. If I shut down the Playstation, the No signal detected message remains. If I DISCONNECT the PS4 from the switch altogether (essentially duplicating the "solo" configuration I tested at the beginning), the error message remains. Only by completely removing the switch from the Roku and routing Roku audio/video to the TV through a dedicated HDMI cable do I regain functions.
There seem to be some "smart" things going on here this dummy doesn't get.
I really want a reliable way to switch between these two sources, as the devices are in a built-in, and manually switching the TV input HDMI is a real pain. Anyone have an idea what is going on, and how it might be fixed?
