Your laptop screen is made up of thousands of small dots of color, called pixels. Each pixel is comprised of three subpixels to produce the image on your screen. These subpixels– red, blue and green– cycle electronically to display the right color necessary for the image. Any of these subpixels can get stuck “on” and display a single, solid-colored pixel. Stuck pixels can happen due to making problems in the LCD, or from damage to the screen.
Pixel Problem or Dirt?
In many cases, what looks like a line of stuck pixels could really be an external thread or hair stayed with the laptop screen. Use a can of compressed air to blow any loose debris from your screen. Tend to stubborn spots with a soft, lint-free cloth to ensure your screen is tidy. Wet the cloth somewhat to wipe dried spots clean, if needed. When you’ve verified that the odd line is not a wayward hair or speck of dust, you can fix even more.
Check Your Display Settings
Seeing your laptop while utilizing the incorrect settings can cause various unusual lines and on-screen behavior, so inspect your screen settings. Open the Control Panel, click “Hardware and Sound” and examine under the Display option. Here you can reset the display’s screen settings to see if you can eliminate the line. Inspect your laptop’s manual to validate the appropriate display and resolution settings for optimum viewing.
Repairing Stuck Pixels
You can try to knock the stuck pixels out of the “on” position by running a pixel-repair program. These are normally discovered for free online (see Resources). These programs normally cycle your whole screen, or just the issue area, through different colors to require the stuck pixels back into typical operation. This can sometimes take hours, so run the utility when you do not have much else to do on your laptop. Another choice is to try and massage the pixels to unstick them. Use a blunt-tipped object, such as a PDA stylus, wrapped in a soft cloth and apply gentle pressure for about 10 seconds to the stuck pixels. Remember where the bothersome pixels are on your screen and turn the screen off first. Turn your screen back on and look at them. Repeat if essential.
Examine Your Warranty
If your laptop is brand-new, examine your maker’s warranty for information about the return or replacement policy. A whole line of stuck pixels, specifically on a new laptop, normally points to a production defect. Lots of laptop brands use a repair work or replacement policy for screens with a minimum of 5 dead or stuck pixels. When in doubt, contact your maker and ask.
