Where the numbers come from
Lowest price seen for the product on Amazon.com, shipped to New York 10001, on the day it was read, before sales tax. The line groups the TVs from the same brand and series. A pair is created when someone searches for both lines together, when one succeeds the other, when they share a brand and price range, or when they are the highest-scoring ones from two brands in the same segment.
The spec score doesn’t measure real contrast or durability, and the verdict by use is a comparison of numbers, not a buying recommendation.
