It can be annoying to have a dead or stuck pixel on your screen. Here are the top techniques for checking your screen and repairing dead pixels.

Your TFT, OLED, or LCD screen’s bothersome dead pixel may just be stuck and simple to fix. You’ll see how to do it from us. If this doesn’t work, you can still return your monitor because nothing we suggest here will void your warranty.

Let’s look at some fixes for heated, dead, or stuck pixels on screens.

How to Check for Stuck or Dead Pixels on New Screens

Yes, you should check for defective pixels on any new display. Using a programme like EIZO Monitor Test, you can quickly test your screen in full-screen mode with a range of primary colours and black and white.

By EIZO Monitor Test

You can locate stuck pixels using the web application EIZO Monitor Test and eventually resolve them. It crams a lot of options into a little test window, but once you get a handle on everything, it’s simple to use.

Check all the boxes you wish to test on your screen before you start. The default setting, with all boxes checked, is what we advise. Open the test on a different monitor if you’re testing several displays. Click Start test to open the full-screen test window when you’re ready.

See the first test pattern down below. In the lower right corner of each screen is a description of what to look for. Next, you’ll notice a menu on the left that allows you to move from one test to the next. Check our screen after moving through the screens in all the solid hues (green, blue, and red) and black and white. Press the ESC key or the exit icon in the top right to leave.

We advise utilising a programme like UDPixel or JScreenFix to flash a bad pixel if you find one.

Test By Online Monitor Test

This is a highly complete test that is strong enough to evaluate the calibre of your display in addition to identifying faulty pixels. Unfortunately, you will probably need to use the executable version to make Flash operate since most browsers no longer support it.

To test your screen, you can select one of three modes. What you should see when you execute the executable is as follows:

A menu will display when the mouse is moved to the top of the test window. A button in the top right corner of the menu allows you to close the info window. Click the Homogenuity test point after that, and then toggle between the three hues and black and white.

I’m crossing my fingers that you won’t find anything unusual. Let’s examine if it’s a stuck or a dead pixel and what you can do to fix it in the sad event that you do.

Is the Pixel Dead or Stuck?

What if you notice a strange pixel? Is what you observe actually a dead pixel or just a trapped pixel?

Because it receives insufficient information, a stuck pixel, sometimes incorrectly called a hot pixel, is flawed. As a result, it shows up in one of the three colors—red, green, or blue—that can be created by its three sub-pixels. Hot pixels in digital cameras only really show when electrical charges get into the camera’s sensor wells. The trapped pixels can sometimes self-correct.

All of the sub-pixels of a dead pixel are always off, giving the pixel a black appearance. A faulty transistor may be the root of the problem. But on sometimes, even a black pixel could simply be stuck.

Therefore, if you spot a coloured or white pixel, you might be able to correct it. And while there is little possibility if you see a dark pixel, there is yet hope.

Now let’s discuss how to unstick a pixel.

How to Resolve Stuck or Dead Pixels

A dead pixel can’t be fixed, regrettably. A trapped pixel can, however, be fixed. It’s challenging to distinguish between the two, as I mentioned above. In any case, you might attempt the following techniques:

First, check your monitor in various colour palettes to find any dead or stuck pixels.

Use a third-party tool to flash the pixel with a variety of colours to correct any stuck or dead-looking pixels. We advise LCD or UDPixel (Windows) (online).

As a last resort, you can try the manual approach, which entails rubbing the stuck pixel with a wet cloth or a sharp but gentle object like the eraser on the end of a pencil.

Let’s take a closer look at these techniques and resources.


A stuck pixel cannot be located, but it can be fixed with the aid of JScreenFix. At the bottom of the page, simply click the Launch JScreenFix button.

The programme will open a black browser window with a flashing pixel square in it. To make the screen full-screen, click the green button in the bottom right corner. Once you’ve located the stuck pixel, drag the flashing square there and leave it for at least ten minutes.

Fix By UD Pixel

Windows software called UDPixel is also referred to as UndeadPixel. Using a single tool, it can assist you in locating and repairing pixels. The Microsoft.NET Framework is necessary for the software. The web tools are below if you don’t use Windows or don’t want to install any software.

The Dead pixel locator on the left makes it simple to find any screen anomaly that may have escaped your attention up until this point.

If you notice a suspicious pixel, move to the Undead pixel section, make enough flash windows (one for each stalled pixel), and then press Start. You can move the teeny flashing windows to the odd pixel locations.

After letting them run for a bit, adjust the Flash interval.

PixelHealer (Windows)

This Windows application was created by Aurelitec as a companion to their InjuredPixels programme to find hot, stuck, or dead pixels.

In a draggable window with adjustable size, the PixelHealer enables you to flash a mix of black, white, all primary colours, and a custom colour. You may also set a timer to automatically close the app and modify the flashing interval.

Click the Close PixelHealer button in the bottom right to end the application.

Dead Pixel Test And Fix

On your Android device, this utility can test and repair any dead or stuck pixels.

In Auto mode, let it cycle through all the colours to check for odd pixels on your screen. Start the fix if you do so, and the entire screen will quickly flash with pixels in black, white, and simple colours.

If none of these tools are able to fix your stuck or dead pixel problem, there is still time. You can combine any of the tools mentioned above with your own magical power. On wikiHow, every technique that is available is described in great detail. On Instructables, you may find another another excellent step-by-step tutorial.

Let’s quickly go over one technique:

  1. OFFSET your monitor.
  2. To prevent scratching the screen, get a wet cloth.
  3. Press down on the spot where the trapped pixel is located. Avoid applying pressure elsewhere to prevent the formation of further stuck pixels.
  4. Your computer and screen should be turned on while exerting pressure.
  5. Once pressure is released, the trapped pixel should disappear.

This works because one or more of the liquid’s sub-pixels in a stuck pixel have not distributed evenly. Different amounts of liquid move through the pixel to produce various colours when the backlight of your screen comes on. When pressure is applied, liquid is pushed out, and when pressure is released, liquid is likely to push back in and distribute evenly as it should.

What Should You Do If Your Pixel Is Stuck or Dead?

The next best course of action is to make peace with your lousy pixel when all efforts to revive it have failed. Your screen won’t be destroyed by one unsightly pixel, and you’ll ultimately forget about it. However, you can always get a new display if the flaw impacts many pixels or just really irritates you.

Examine the warranty first. Dead pixels may be covered by the monitor’s maker or the retailer where you bought it. It should be noted that most manufacturers set a maximum amount of permissible defective pixels for particular resolutions, and the warranty won’t kick in until your monitor exceeds that limit.


LG's Pixel Policy is as follows:

The operation of the LCD Monitor is unaffected by bright or dark sub-pixels that may appear during the manufacture of the LCD Monitor panel. If the film of the liquid crystal does not function as intended while the client uses the LCD display, the customer may observe bright or dark patches. However, until the number of bright and dark subpixels exceeds the maximum permitted level, this is not regarded as a defect (…)

According to LG’s pixel policy, the most you should put up with on a monitor with more than 12 million pixels (Wide QXGA+, 2560×1600 pixels), for instance, is 12 bright or dark sub-pixels.

Every pixel reports to the display

If none of these fixes succeed in fixing your dead pixel warrior, at least you now know it’s not something that can be fixed easily; you might even need to replace the screen.


Can dead pixels on a screen be fixed?

Can a Dead Pixel Be Repaired? A dead pixel is 99% of the time a manufacturing or transportation flaw, thus there is sadly no easy solution for you as a consumer to fix one. The only thing left to do at that point is to check your screen’s warranty to see if dead pixels are covered or not.

Are dead pixels erasable?

A problem that is more or less constant and does not go away with time is referred to as a dead pixel. On LCDs and sensors for digital cameras, dead pixels are uncommon; manufacturers typically deal with them as part of their thorough Quality Assurance (QA) procedure.

How can a dead pixel be revived?

Let’s quickly go over one technique:

  1.  OFFSET your monitor.
  2.  To prevent scratching the screen, get a wet cloth.
  3.  Press down on the spot where the stuck pixel is.
