How much is a used computer monitor worth?

Most used computer monitors resell for about $20–$70. A larger (27"+), high-refresh-rate, or curved gaming monitor in good shape can bring $70–$200+, while a small, old, or lower-resolution office monitor usually moves for $10–$30. The one thing that can zero it out instantly: dead or stuck pixels — a monitor with even one is worth far less, sometimes nothing, to most buyers.

That's the short version. Here's how to check a monitor before you take it.

Used computer monitor value range

Type / condition	Est. resale range
Old/small (17"–20"), 1080p or lower	$10–$25
Standard 22"–24" office monitor, 1080p, working	$20–$45
Larger (27"+) 1080p/1440p, no gaming features	$40–$80
High-refresh-rate or curved gaming monitor (144Hz+)	$80–$180
Ultrawide or 4K, name-brand	$100–$250+

Estimates only — actual resale depends on size, resolution, refresh rate, panel condition, and local demand. Not guaranteed.

What drives a monitor's resale value

Dead/stuck pixels. This is the single biggest value killer. A dead pixel (permanently black) or stuck pixel (stuck on one color) is visible on a plain white or black background and can't be fixed — check for this before anything else.
Size and resolution. Bigger and sharper sells for more, generally — 27"+ 1440p or 4K monitors have real demand; small 1080p monitors under 22" are common and cheap even in perfect condition.
Refresh rate. Gaming-oriented monitors (144Hz, 165Hz, 240Hz) command a real premium over standard 60Hz office monitors of the same size, driven by PC gamers specifically.
Ports present. Confirm what inputs actually work — HDMI, DisplayPort, USB-C. A monitor missing its stand or with a broken port is a much harder sell even if the panel itself is fine.
Screen condition. Scratches, especially anything visible with the screen off and a flashlight at an angle, matter more than most buyers expect — a scuffed bezel is cosmetic, a scratched panel is not.
Brand. Dell, LG, ASUS, Samsung, and gaming brands (Alienware, ASUS ROG) hold value better than unbranded or store-brand panels.

Is a used monitor worth flipping?

Yes, if you can test it for dead pixels and confirm the ports work — this is a category where a five-minute check prevents you from hauling home something unsellable. A working, pixel-clean monitor is a solid flip for very little cleaning effort. The risk is entirely in what you can't see from a curb photo: a single dead pixel or a cracked-but-still-functioning panel underneath an intact-looking bezel.

What to grab: seller can power it on so you can check for dead/stuck pixels, larger sizes or higher refresh rates, all original cables if possible. What to skip: anything you can't test before taking, visible cracks or "bleeding" light spots near the edges of the screen, missing stand with no VESA mount option.

How to flip a free computer monitor

Power it on and check for dead pixels, if at all possible — pull up a plain white or black background (even a phone flashlight bounced off the screen can reveal stuck pixels) and scan the whole panel.
Test every port you plan to advertise — HDMI in particular is common enough that buyers expect it to work.
Wipe the screen with a microfiber cloth only — no household glass cleaner, which can damage anti-glare coatings.
Note the exact model number (usually on a sticker on the back) — buyers search by model far more than by generic description.
Photograph it powered on showing a clean picture, plus the ports and stand/mount.
List & hand off. Facebook Marketplace, OfferUp, and local PC-building/gaming groups all move monitors quickly — mention refresh rate and resolution explicitly if it's a gaming-spec panel.

Where free monitors come from

Monitors get replaced constantly — office upgrades, a move to an ultrawide or multi-monitor setup, or a company disposing of old equipment. Because a working monitor with zero dead pixels looks identical to one with a single dead pixel in a photo, sellers often give them away rather than deal with buyers who show up and reject it on the spot.

FAQ

How much is a used computer monitor worth? Most used monitors resell for about $20–$70. Larger, high-refresh-rate, or curved gaming monitors can bring $70–$200+, while small or older 1080p office monitors typically sell for $10–$30.

Is it worth flipping a free computer monitor? Yes, if you can test it for dead pixels and confirm the ports work before taking it. A clean-panel, working monitor is a solid low-effort flip; an untestable one is a real gamble because a single dead pixel can tank the value.

How do I check for dead pixels on a used monitor? Power it on and display a plain solid white and solid black background — a dead pixel shows as a permanent black dot, a stuck pixel as a dot stuck on one color (often red, green, or blue). Scan the whole panel, including corners.

Do gaming monitors resell for more than regular monitors? Yes — monitors with high refresh rates (144Hz and up) or curved gaming-oriented panels command a real premium over standard 60Hz office monitors of the same size, driven by PC gaming demand specifically.

Where do people give away free computer monitors? Office equipment upgrades, moves to a new monitor setup, and general electronics decluttering — curbsides, Buy Nothing groups, and the free filter on Facebook Marketplace and OfferUp.
