The reason why you are getting these green pixelation is because an LCD produces a particular range of colors and visuals by changing the colour 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.

Solution 1 - 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 this online solution 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.

Solution 3 - Apply 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.
