Should I buy an LG 4K TV?

Episode 1329 (12:14)

Jeff from West Los Angeles, CA
LG 4K TV

Jeff is looking at an LG 43" 4K TV with WebOS. Leo says that LG makes excellent TVs. 43" is kind of small for watching, though, especially for sports. If he can afford to go larger, Leo says he should. It all comes down to the "spousal acceptance factor." Would it be better in a dark room or lighter room? Leo says that LCDs are better in rooms where he can't control the lighting.
