WRT "It's designed to select inputs"- how, CEC?
Nope. I missed the importance of the fact that I only had one input connected.
you have something connected ONLY to TV Input HDMI 1
you try to select HDMI 2
the TV goes to HDMI 1
You cannot tell if it is choosing the wrong input because of something about the signal, or it's just choosing the only connected signal.
On top of that, audio did not play when it should have.
Here's an example of what I was looking for:
Press mute 7 2 9 EXIT
This toggles HDMI autodetection on and off
I haven't been to the site yet to see the results of this.
It's possible to make some other adjustments to the way the set works. Samsung provided this one to me, but the guy was loath to just tell me everything, probably because they don't want the average person, or even installer, to have this power at their fingertips.
