How to read these numbers

Pick 1, best score for the price: BenQ XL2540K, £300 at Amazon. The median price of the 119 models on the list is £100.

How we choose
  • The picks combine a high rating and a price in line with the list: each one fits a way of spending, a use, or the brand that shows up most. The pros and cons come from each model’s spec sheet.
  • Stores: Amazon. We include stores we read every day through an open source or an affiliate program: the Radar collection, the Amazon catalog and the factory price database. A store that failed to load today is left out.
  • The same model in two stores is only merged with a catalog code, GTIN or the manufacturer’s full code. When in doubt, only one store is kept. A price far from the collected one (below 60% or above 150%) is left out.
  • Amazon appears without a price, only with the link: we don’t read Amazon prices in bulk.
