Green stuck pixel on an IPS panel: what to do

A tiny green dot on a dark screen is hard to ignore. If it stays in the same place while images change, it may be a stuck subpixel, but first rule out a mark in the picture, a software overlay, or a graphics issue.

Use a full-screen color test to check whether the dot stays fixed on the panel. If it does, you can try the Stuck Pixel Fixer, which flashes colors in an attempt to free a stuck pixel. It may help, but it cannot repair every panel fault.

Check whether the green dot is on the panel

1. Open the Display Test and show full-screen colors, including black, white, red, green, and blue. Look at the same physical spot on the screen for each color.
2. Move a window or the test pattern so different content appears underneath the dot. If the dot remains in exactly the same place on the screen, it is less likely to be part of an image or app.
3. Take a screenshot and view it on another screen, or send it to another device. A physical panel pixel fault usually will not appear in the screenshot. If the dot appears in the screenshot too, investigate the image or graphics output instead.
4. If the spot remains fixed on the panel, open the Stuck Pixel Fixer. Follow the on-screen timer and let the flashing pattern run only if you are comfortable doing so.

Check the display at a normal viewing distance as well as close up. Dust, a tiny mark on the screen surface, and a pixel defect can look similar when viewed from very close. Do not press or rub the panel to investigate.

What the result means

The green dot stays in one place on every color

This points to a panel pixel or subpixel that is stuck on. A pixel is made of red, green, and blue subpixels. If the green part remains lit while the others change, it can look like a small green point, especially on black or dark gray. A green dot does not by itself mean the whole pixel is permanently damaged.

The mark changes or moves with the picture

The cause is more likely in the image, app, or graphics output than in one physical pixel. Close overlays, menus, and apps that draw on top of the screen. If the mark appears in screenshots viewed elsewhere, check the original image or graphics software.

The spot disappears on some colors

A subpixel defect can be easiest to see against a particular background. A green subpixel may blend into a green test screen and stand out on black, red, or blue. Check several solid colors before deciding it has gone away.

The flashing pattern does not change it

That does not prove the panel is defective, but it means the browser-based attempt did not free the subpixel. Some stuck pixels respond, some do not, and a browser tool cannot replace a damaged panel component.

What to try before returning or repairing it

1. Rule out a temporary image. Close other windows and apps, then repeat the color check. Restart the computer if the mark appeared after a graphics glitch or waking from sleep.
2. Check another connection or source. If it is an external monitor, try another video input or connect a different device. A dot that stays at the same physical point across inputs is more consistent with a panel issue than a source issue.
3. Confirm the display mode. On Windows 11, open Settings › System › Display › Advanced display and check that the monitor is using its recommended resolution and a supported refresh rate. On macOS, open System Settings › Displays and select a normal resolution and refresh rate. These settings rarely fix a stuck subpixel, but they can rule out an unusual scaling or signal problem.
4. Try the flashing pattern cautiously. Run the Stuck Pixel Fixer for a short period, following its timer, then check the same test colors again. Stop immediately if the rapid changes make you uncomfortable. Do not leave flashing patterns running unattended.
5. Check the return and warranty terms. If the dot remains, look up the seller's return window and the monitor maker's pixel policy before attempting further fixes. Policies can set a minimum number of defective pixels, and the rules may differ for bright and dark pixels.

When the panel is probably at fault

A green point is more likely to be a panel defect if it remains at the same physical location across full-screen colors, apps, and input sources, and does not appear in a screenshot viewed on another device. Those checks are useful evidence, but they cannot identify the exact failed component.

A budget IPS panel is not automatically defective because it has one stuck subpixel. Lower price does not tell you whether a particular pixel can be repaired, and manufacturers use different pixel policies. If the monitor is new, contact the seller while the return window is open and provide clear photos of the test colors and the location of the dot. For an older display, compare the cost of panel replacement with the cost of a replacement monitor. Panel repair is often not economical for one isolated subpixel.

Use flashing patterns with care

The Stuck Pixel Fixer rapidly changes colors in an attempt to make a stuck subpixel change state. It is not a guaranteed repair and does not fix dead pixels, damaged panel wiring, or every other display problem. Rapid flashing can be uncomfortable or unsafe for some people with photosensitivity. Read when pixel flashing may be unsafe before using it if that concern applies to you, and stop if you feel discomfort.
