We've bought three Samsung, so called "Smart TV's" from Costco. All over $1200. Two are 4K UHD. Tried to pair a Samsung keyboard to them. Guess what Costco neglected to tell the customer? These don't have Bluetooth!
THEN THEY ARE NOT SMART TV'S!!!!!!
Never going to buy another Samsung and certainly not going to shop at Costco for a TV again!
