New Mini LED style technology
Parents Just got this TV. Perfect for a bedroom TV. It does have some drawbacks that i would prefer to not have like my OLED but for its class and level it is a wonderful TV. Even though some apps arent useable thats what i have a firestick for. Samsung kills it again with a great upper middle of the road going into a more premium modeling for their TVs. Highly recommend a soundbar however as good as the TV sounds the depth isnt the same as it is with the higher 90 series model.

Avoid if you use Spectrum TV App
DON'T buy this TV if you use the Spectrum TV App. The model is not compatible with the App. I have spent hours trying to figure it out with Samsung Support. All they can tell me is that the Spectrum TV app is not compatible with this model. They will not tell me if there is an update coming that might be able to correct this.
