In the 6 Nov 2026 catalog, the median price of the 77 models in the segment is £100, and prices range from £64 to £300. The final price is the one at the store.
Included are models 23 to 24 inches, listed in the specs (the size is in the specs of every monitor in the catalog). With at least one version at the lowest collected price up to $400. Each model counts once: if it has more than one version within the rule, the price is that of the cheapest version and the others show on the card.
From cheapest to most expensive, the monitor that has a higher spec score than all the cheaper ones in the segment makes the line. Anything that costs more and has an equal or lower score is left out. The line doesn’t say which monitor to buy: it only shows which ones don’t lose on both score and price at once.
Every day, with each collection: numbers, chart, ranking and the "What changed" section are rebuilt with the day’s catalog. This edition is from 6 November 2026.
Lowest price seen for the product on Amazon.co.uk, delivered to London SW1A 1AA, on the day it was read, including VAT.
