I have a crap old TV and my mates all have swanky smart ones. But the smarts mean they are 20-90s behind live matches. So in the group chat I am a genius with my comments because I see the future.

@fesshole That delay is down to how they're watching, not that they're necessarily using a smart TV.

Watching DTT (via an aerial, aka Freeview) on a smart TV isn't significantly more delayed than watching it on a dumb TV. Watching anything from a streamer (iPlayer, NowTV etc.), however, will be very delayed.

@gilester45 @fesshole

there's a variation of a maybe 0,25 - 0,5s lag between DTT TV sets all in the same building (I noticed it when I worked on maintenance in a senior home and there was sportsball or something else popular that everyone was watching in their rooms and I was walking down the corridors), but for whole seconds delay thats more likely due to streaming services..
