Is there a class for smart TV?
When choosing a smart TV, you should focus on prioritizing the picture quality, generally speaking the better the picture quality, the more expensive the model, not the more powerful the performance. So the grading is mainly done according to the picture quality processing technology of LCD TVs.
Low-end TVs generally have no picture quality processing technology, but the hardware performance configuration meets the basic requirements.
Mid-range TVs at least use motion compensation + wide color gamut function, and hardware performance is similar to or better than low-end machines. According to the user sharing in the VIZIO TV forum, most VIZIO TVs belong to mid-range TVs, which are characterized by inexpensive price and average experience. Of course, they also have better TVs, but the end-of-the-line cost-effective TVs are the most popular.
Mid-range and high-end TVs
Mid-high-end TVs feature at least motion compensation/wide color gamut/light control partitioning/peak brightness of 600 nits and hardware performance similar to or better than mid-range sets.
Quasi-high-end TVs should have motion compensation, wide color gamut technology, checkerboard light control partitioning, high peak screen brightness (≥800 nits), and high screen refresh rate (120hz). Most LG and Sony TV's fall into this or better classification and comparisons are made between the two, such as their popular TV, Sony A80J vs LG C1.
High-end TVs should have motion compensation, wide color gamut technology, checkerboard light control partitioning, high peak screen brightness (≥1000 nits), high screen refresh rate (120hz), picture quality processing chip, and the lack of one of these features.
