The cheapest monitor we hold a verified price on is the LG 27GP850P-B 27-inch Gaming from £105 (used). We don’t currently hold a verified refurbished monitor price — every screen in the list below is a used (or new) listing we could verify. On a monitor the panel is what matters, so a graded unit tested for dead pixels and backlight bleed is worth holding out for if you want the assurance.

Used is the cheapest route and sold as-seen, and on a monitor it is the panel — not the cosmetics — that decides whether it’s a good buy. Ask about and then test for dead or stuck pixels, backlight bleed and IPS glow on dark scenes, and, on OLED panels, image retention or burn-in; if the listing shows panel hours, factor those in. Check the right stand and the power and video cables are included — replacements cost real money and the correct stand can be hard to source. A scuffed bezel matters far less than a clean panel.
Refurbished (and certified refurbished) costs more because the monitor has been tested — including for dead pixels — and restored, typically with the stand and cables and a warranty, often 12 months. A private used listing carries none of that. On a higher-end panel you’ll keep for years, that tested-panel assurance is often worth the premium; on a cheap office screen a graded-used unit usually wins on price.
Read the title and condition together. A low price next to “for parts”, “spares or repair”, “cracked screen”, “lines on display” or “no stand” is honest about a broken or incomplete unit — not a working monitor. “Collection only” is common and often sensible: monitors are fragile and dear to post, and courier damage in transit is a frequent cause of dead-on-arrival screens. Be wary too of stock-photo relists that hide the actual panel’s condition.
Our matcher takes precision over recall: where a monitor price is unverifiable or counterfeit-suspect — no trusted anchor, a part-only or wrong-model listing — we suppress it rather than show it. The prices above are the ones that survived that filter, so a “too cheap to be true” listing never becomes the headline here.
The strongest value is ex-office and business monitors and last-generation gaming panels bought used. Ex-corporate screens are plentiful, well looked after and heavily discounted; gaming panels drop sharply the moment a newer model lands, even though the older one is still excellent.
Buy for how you’ll use it. For work, prioritise resolution and size — 27-inch 1440p is the comfortable default, 4K for fine detail and more desktop space, and USB-C if you want one cable to a laptop. For gaming, a high refresh rate and low response time matter more than raw resolution. For creative work, prioritise colour accuracy and panel quality (IPS or OLED).

Yes, with the right checks — monitors last for years and take far less wear than phones or laptops, so used ones are often strong value. The single thing that decides a good buy is panel condition: ask the seller about dead or stuck pixels, backlight bleed and (on OLED) any image retention before you commit, and test it within your return window on arrival. Cosmetic scuffs on the bezel or stand matter far less. Confirm the correct stand and the power and video cables are included, as replacements cost real money.
Set the monitor to full-screen solid colours — a pure black, then white, red, green and blue. Dead pixels show as permanent black dots and stuck pixels as dots stuck on one colour; on a full white or grey screen you can spot dirt and uniformity issues. Backlight bleed and IPS glow show up on a full black screen in a dark room as lighter patches, usually at the corners — a little is normal on IPS, large bright patches are not. On OLED, display a static high-contrast image briefly and check nothing faintly lingers when it changes (image retention).
Usually, yes. Graded refurbished and certified refurbished monitors are tested — including for dead pixels — and typically include a warranty, often 12 months. A private used listing is sold as-seen with no cover. That testing and warranty is what the refurbished premium buys you. At the moment we don’t hold a verified refurbished price on any monitor we track — every priced screen below is a used listing we could verify.
Often a lot — monitors hold up well, so used and ex-office units frequently undercut new by a wide margin, and last-generation gaming panels drop sharply once a new model lands. The saving is biggest on higher-end screens (4K, USB-C docking, OLED, high-refresh gaming). On cheap office monitors the used saving can be small enough that a new one with a full warranty makes more sense.
It depends how much assurance you want. CEX is strong for graded, warrantied used stock with easy returns; eBay often has the lowest outright price and plenty of ex-office and last-gen gaming panels, but assurance varies by seller and monitors are fragile to post — favour tested sellers or collection where you can. This page tracks the live cheapest verified price — currently from £105, and we leave out listings we can’t verify.
