Should I buy a 40" 4K TV?

Episode 1298 (1:31:50)

Sid from Valencia, CA

Sid wants a 40" HDTV and he's been told to get a 4K model. Leo says that a 40" screen is too small to see the difference between 4K and 1080p, so he may as well save his money and stick with 1080p. There's no 4K content on broadcast or satellite, either.
