Thanks! That was very informative!

I'm still puzzled about why the #HDCP error would go away just by un/replugging the #HDMI cable between the #Roku and the #TrueMatrix switch, though. It sounds as though it should be a persistent error. (Which in fact it was when I tried to replace the cable between the #Sony #Bravia and the switch.. maybe I should have tried the one between the switch and the Roku. 🤔)

Throwing this out to the #Mastodon-verse..

Why the flying moose ears does my #Roku Express 2 keep gritching about an #HDCP error every time it powers up? And not immediately, either; usually only after I connect to a service.

Unplugging the #HDMI cable from the Roku and plugging it back in solves the problem -- until the next time.

It plugs into an input on a #TrueMatrix 4×2 HDMI switch, the output of which goes to a #Sony #Bravia.

And changing the Roku-to-switch cable just made it worse.☹️
