Where the numbers come from
Lowest price seen for the product on Amazon.ca, delivered to Toronto M5V 3L9, on the day it was read, before GST/HST. 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.
