1) I'm wondering how a new Roku Express 4K stick would work on an old Roku TV (TLC)? Ours TV (2014) is sluggish. Doesn't support apple TV. No longer supports HBO Now. Amazon and Netflix freeze. Does it work well? Or is it not worth the trouble?
2) Would I have to use both the old (TV) and new (Roku plugin) remote? Or would the new remote work to both turn the TV on, toggle to AV inputs (cable antenna, DVD player) and to select apps, etc.?
