On qualifying 2019 Samsung Smart TVs, the model number can be checked by holding the Play/Pause button on the TV remote for more than seven (7) seconds.
An "About This TV" screen will pop up, and the model number - called "Model Code" - will be shown under the "Product Information" section.
If the "About This TV" screen does not pop up after holding the Play/Pause button on the TV remote for more than seven (7) seconds, then you do not have a qualifying 2019 Samsung Smart TV.
In the example shown below, the television model number is "UN43NU7100". Note that this model number is NOT eligible for the free movie rentals promotion.
