Best 4K monitor UK (October 2026)
Top pick: Acer Predator X27 X1, 26.5" · 4K 240 Hz OLED, at £635.99 from AWD-IT.
How we rank
Ranked by picture quality for the money: refresh rate × panel (OLED 1.3, IPS 1.1, VA 1, TN 0.9), counting refresh rates up to 360 Hz (240 Hz at 4K) and dual-mode monitors at their native-resolution rate, divided by the square root of the price, so a better screen can beat a cheaper one. The top pick comes from a shop whose stock we check when there is one. Every new monitor with a 4K screen that a UK shop we track lists with its resolution and refresh rate, one row per model at its cheapest shop; other shops selling the same model are under "also at". Specs are read from the shop's listing title; we don't rate image quality, response time or HDR. Prices (new, UK shops only; listings a shop marks as pre-order or unavailable are skipped; prices we can't check are marked "stock not checked"). 30-day low = the lowest price we recorded for that model in the last 30 days (blank until it has 2 days of history; tracking since 18 Oct 2026). PCHUB.UK, PcNova and GamingKit prices come from their Awin product feed (refreshed about daily, VAT included; the feed doesn't report real stock levels, so these prices are marked "stock not checked"). 1 of these products is listed only by these feed shops so far. We may earn a commission from shop links; it never changes the order.

What to look for
Refresh rate (Hz) is how many times a second the screen redraws: 144 Hz and up looks clearly smoother than 60 Hz in games, if your graphics card can produce those frames. Resolution sets sharpness: 1080p suits 24-inch screens, 1440p suits 27-inch, and 4K suits 27 to 32 inches but needs a much faster GPU in games. Panel type matters too: IPS has the most even colour and viewing angles, VA has deeper blacks but can smear in fast motion, TN is fast but looks washed out off-angle, and OLED has true blacks and the quickest response but costs more and can burn in with static images. HDR labels vary a lot: an HDR400 badge on an ordinary LCD adds little, so check reviews before paying extra for HDR.
How the ranking works: Ranked by picture quality for the money: refresh rate × panel (OLED 1.3, IPS 1.1, VA 1, TN 0.9), counting refresh rates up to 360 Hz (240 Hz at 4K) and dual-mode monitors at their native-resolution rate, divided by the square root of the price, so a better screen can beat a cheaper one.
