Fix using UndeadPixel (Windows)
UndeadPixel, aka UDPixel, is a program designed to specifically locate and fix dead or stuck pixels. It hasn’t been updated in more than six years, but it still attempts to fix pixels in the way it always has: by rapidly cycling them through a series of sporadic color changes for several hours. The freemium software currently runs on most Windows operating systems — Windows 2000 through Windows 8 — and features a light footprint and a simple, self-explanatory interface. It’s not a powerhouse utility by any means, but it can get the job done in a pinch without extraneous features and annoying bloatware.
1. Download UDPixel: Head to the UDPixel download page and select the latest release of the self-installing EXE package at the top of the page. Then choose your desired save location and click the Save button in the bottom-right corner of the popup window.
2. Install UDPixel: Once the download is complete, navigate to the installer and launch the software. Select the component you want to install, most notably UDPixel, and click Next in the bottom-right corner. Then choose your destination folder and click the Install button to complete the installation.
3. Launch UDPixel: Open the newly installed program by clicking the Start menu and accessing it through the All Programs option at the bottom of the drop-down menu. Alternatively, locate and open the file using the Windows search bar feature.
4. Locate the questionable pixel: Clicking the colored panels on the left-hand side of UDPixel will change your screen to the corresponding hue. Click through the six colors individually or choose to cycle through them automatically by clicking the Run cycle button at the bottom of the color list. A dead or stuck pixel will stand out against every backdrop except for the color it’s stuck in. Continue doing so until you find it and make a mental note of its location on the screen.
5. Start UDPixel flash windows: Choose the number of flash windows, the window size, and the flash interval on the right side of the window beforing click the Start button. Afterward, reposition the flashing window(s) directly over the dead or stuck pixels and let the process continuously run for several hours.
6. Check the results: Click the Reset button in the bottom right of the window when finished and run the same cycle you used to locate the dead or stuck pixel in step 4. Check to see if the questionable pixel has returned to normal, and if it hasn’t, choose an alternative method.
