How we choose
Source: Amazon.ca catalog, checked on 12/11/2026.
Lowest price seen for the product on Amazon.ca, delivered to Toronto M5V 3L9, on the day it was read, before GST/HST. 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.
