I have a hunch that television manufacturers are going to have to pay to get their TVs labeled with the “Netflix Recommended TV” logo. Which means there very well could be TVs that perform better than those with the certification from manufacturers who have chosen not to pay for the right to use the label.
Personally, I wouldn’t suggest anyone purchase a television with this certification or any other smart TV features anyway. It’s only a matter of time before your set gets abandoned by the manufacturer and you no longer receive software updates. Save yourself the money, buy a “dumb” TV, and use the money you saved to purchase an Apple TV or a Roku box.
