Silverwook, I do fully understand - it is a financial stinger to upgrade, and the amount of 4K content is still rather low.

I think most people need some sort of extra ‘motivation’ to splash out on UHD. For some gaming is the catalyst (with PS4 Pro and Xbox One X), for others it might be a particular movie - such as The Last Jedi or 2001. We are still a little way off from regular TV shows being routinely broadcast in 4K.

But you don’t need a 100" screen to see a difference, I’d say anything from 50" upwards is going to treat your eyes to very obvious, unambiguous next level visuals when compared to 1080p.
