    Samsung products do not disappoint.

    This TV is replacing a 2016 Samsung model in our living room and appears to be just as good. It is our primary source of entertainment. We are still learning to use all the new features. Audio is much different and may have to get a grandkid to help with the settings! The remote is challenging for senior citizens until you get used to it.

    Great Product Great Value

    Love this TV! The colors pop! Picture is great. Set up is super easy. I only wish the volume more range. Even with the volume at the highest, it is not loud enough. We had to buy a soundbar to get the range we wanted so we did not blow the soeakers.

Questions & Answers

  • Hi, does 4k upscaling have to be turned on or is it automatic? I purchased 1 week ago..

    Hi jimt, 4K Upscaling is integrated into the TV's processing. If you're unsatisfied with the current image quality, a note that your TV is designed to upscale content to the best possible quality based on the resolution of the source. In general, the closer your content is to native 4K, the sharper and more detailed it will appear on screen. We're happy to help if you'd like any tips to adjusting image to your liking. Feel free to contact Samsung Support online via the Support tab or over the phone. ~ Samsung Ambassador
