I wrote this Samsung UN75NU8000 review for helping you to understand if this TV meets your requirements. This model belongs to the NU8000 series, which also includes other high-performance models.
This is a 2018 year model and it belongs to the high-price class, since it may cost you more than $1,000. This TV uses the Edge LED backlight technology. It supports the 4K standard with the HDR10 technology. Moreover, it features the Dynamic Crystal Color technology that makes colors even more vivid. The motion rate 240 eliminates any motion blurring during the most dynamic scenes. You can control this TV with a smart remote (it also controls the compatible devices connected to the TV).
Another Samsung UN75NU8000 specs - the Bixby voice control technology which allows you to search content, change channels or even ask questions using your voice. It also has a Wi-Fi module.
