How we choose

Source: Amazon.com catalog, checked on 12/11/2026.

Lowest price seen for the product on Amazon.com, shipped to New York 10001, on the day it was read, before sales tax. The model is the brand plus the name of the monitor; the versions go in the table. The price range, the median and the position use only models with a score; the price comparison looks at models whose score is within 0.5 points.

The spec score doesn’t measure the real calibration or durability, and the strong or weak point reading is just a comparison of numbers, not a buying recommendation.
