Power up the new Samsung QLED 8K TV and you may find yourself questioning reality. When your team scores a goal, you’re right there in the stadium, celebrating amongst the riot of scarves and chants. When the building blows in the latest action film, you’re pressed back against the sofa, practically feeling the heat. When a tropical fish flits by in a nature documentary, you’ll reach out expecting it to brush your fingertips. You’re no longer watching TV. You’re living it.
