We have a TV with a stick in our living room and a roku tv in the kitchen. When playing the same tv channel (Spectrum’s app) in both rooms, the roku tv is about 2 or 3 seconds behind in playback - so we get an echo. Is there a way to get the two TVs synchronized???
Sorry, but no.
It's not just differences between Roku devices, but even TV's themselves have various delays for their internal processing.
