Noticing that captivating green dot on your monitor can seem to be fuzzy and bizarre. However, it is irritating and concerning, as it can indicate an underlying hardware issue. Most of the time, it is not a single green pixel or dot but a series of green pixels flickering on the monitor. The same pixels reflect the green color all the time, even when you turn the monitor ON the next time.
Regardless of what you do, these pixels stay in place due to which they are likely to be distracting too. These dots are actually stuck, and thus, are known as stuck pixels. Unlike the dead pixels in black, the stuck pixels are typically red, green, or blue.
Both stuck and dead pixels can emerge on LCD screens. Due to the color, it is easier to spot them on big monitors. However, if your screen is showing something that is multi-colored, it is tough to spot them. To spot them, it is essential to have the screen reflecting only a single color.
The good news is that the stuck pixels are not a big problem, as they are not permanent. They are usually the result of manufacturing defects; they are not meant to get stuck or perish with time.
What Causes Green Pixels on LCD Monitors
An LCD produces a particular range of colors and visuals by changing the color of several small pixels on the screen. Each pixel is composed of three sub-pixels namely, blue, red, and green. Small transistors in the screen activate the right color by electronic means.
A couple of factors can result in making these pixels stuck on a specific color. Some of these common factors are manufacturing flaws and screen damage. These pixels can be single small dots or lines that run across the screen.
How to Fix Green Pixels on Monitor?
You can easily fix the green pixels flickering on the monitor without much effort. However, before you try them out, it is important to ensure that the issue is with the LCD screen. So, you should first verify the issue’s source.
For this, you need to know that three hardware parts contribute to a display on the LCD monitor, which are the monitor, the graphics card, and the cables attaching them. If one of these components is facing an issue, it could result in those distracting green lines. Depending on which component is having the issue, the solution shall differ.
To smartly verify the issue, just use a second monitor instead of the problem-causing one to see whether the pixels still appear or not. If they do, it means that the cause of the problem is the graphics card.
Malfunctioning or obsolete drivers of monitor and graphics card and pending Windows updates can also cause green pixels. So, it is wise to update them. Otherwise, you may have to replace the graphics card.
Now, check the video cables to spot the symptoms of damage and wear. If they exist, consider replacing the cables. At times, you simply need to tighten the loose monitor cable or screw in the VGA cable properly into the monitor to fix the green pixels issue.
Next, check the display settings of your monitor and ensure that they are set to give optimal performance. In these settings, ensure that the color settings are as per the norms specified in the manual. Once you have found that the issue is with the LCD screen, try the following solutions.
Solution 1: Stop Using Your Monitor for a Day
The easiest and the first solution to try to fix the issue of green pixels is to stop using the monitor for 24 hours. Doing so is likely to fix the issue if the pixel got stuck recently. While it may not necessarily fix the issue, the chances are high for it to resolve. This is because a stuck green pixel is often the result of screen overuse, indicating to shut down the monitor for a while to keep any further harm at bay.
Solution 2: Use a Third-party Tool
Luckily, you can fix the issue online without making any special effort. There are a few effective pixel fixer tools online (like this one) that allow identifying and fixing stuck pixels. They work by swiftly cycling through the colors to which the subpixels respond to restore themselves.
They cycle the screen via various colors to release the stuck pixels. Expect them to take around 20 to 60 minutes to fix the issue. These tools are mostly available online although you may find their free download versions too.
Some of these popular tools are JScreenFix and Undead Pixel. While the latter one is available as a free download, the former one detects and fixes the issue online. Here, you only need to make the screen go into full mode and then let the tool do the rest.
However, just ensure that you clean your screen before doing so, as otherwise, you will then consider a line of dust as stuck pixels.
Solution 3: Perform Pixel Press
Many people have found that applying a little pressure on the ON green pixels can restore them to their normal state. You can do so by pressing or rubbing gently using a tool or a material that will not harm the screen.
You can start by turning OFF the monitor screen and using a small chunk of tape to mark the length of the line. Now, dampen a soft cloth a bit and apply it gently along the marked line. Just do not press hard, as it will make the issue worse.
The underlying notion is to lightly tighten the screen material and kindle the inside pixels to move out of their ON position. Once you are done working along the line, turn ON the screen to view the line.
Alternatively, you can tap the green line slowly with a narrow and blunt (not sharp at all) item, such as a sharpie’s cap covered with a cloth.
These solutions will surely help you fix the issue. If not, it is time to seek professional help.
