Thank you for contacting Samsung.
This TV is 120Hz. All TVs in the U.S. function off 120V @ 60Hz, which is the standard power supply in the U.S. You'll see this printed on just about anything electrical you plug into the wall, so that's where some confusion comes into play.
If you have any additional questions, we suggest your refer to your product manual or the product support page on our website, where you'll find a comprehensive troubleshooting guide, product support videos, FAQs and How-Tos, as well as manual, software, firmware & environment downloads.
Thank you for being a Samsung customer!
