Hopefully on the latest ROKU 12 OS update advance action smoothing will be available. even just in the roku app. LIke adding a slider bar or measurement from 1 to 10. That would be great.
Not just 120hz roku tv, but most roku tv's.
Unless it's one of the new Roku TV's that just came out a week ago, it will be up to Vizio, TCL, etc... to add hardware features.
