Do you happen to know what the model names/numbers of your two Roku devices are? The model number should be found on the bottom of the unit, printed in either a white text on a label or a black outlined/moulded text, usually something like “Model No.,” then usually the four digits and the letter X. I have a 2017/2018 Roku Express + (the one with analog outputs) and it’s model no. 3910X.

I’m into videotapes and old electronics stuff, including extenders, converters and analog 4:3 TV sets (which are obsolete these days), and Miss Bianca is my favorite character in Disney’s The Rescuers (1977) and its sequel, The Rescuers Down Under (1990). I am not a Roku employee, only a user like you. ~ Jordan
