Not long ago, I came across an old monitor that a friend planned to toss out as e-waste after upgrading his setup. It’s from a reputable brand, boasting a 1080p resolution and a refresh rate that seemed adequate for casual gaming.
The idea of having a second display thrilled me, and I was genuinely appreciative of his kind gesture. The picture quality appeared decent enough, but being a tech enthusiast, I decided to run some diagnostics to assess its color accuracy, contrast levels, and resolution.
One essential test I conducted was to check for dead or stuck pixels, which can sometimes plague monitors. To my surprise, I discovered a handful of stuck pixels just left of center.
While they weren’t a dealbreaker—after all, some monitors can have pixels that render them nearly unusable—I decided to give fixing them a shot. I utilized a website called Piksel Test and successfully resolved the pixel issue. Now, I plan to use this test on all future screens I acquire.
If you find yourself in a similar situation with any of your devices—whether it’s a monitor, smartphone, TV, or tablet (regardless of whether they have LCD or OLED screens)—you can perform the same steps.
Steps to Take
- Power on your computer and allow Windows to load.
- Connect to the internet and navigate to the Piksel Test website.
- Select the “Test Dead Pixel” option.
- Identify any dead or stuck pixels on your display. The website provides guidance on how to distinguish between the types of pixel issues.
- Scroll down and click on either “Dead Pixel Repair” or “Stuck Pixel Repair,” depending on what you found.
- Run the pixel fixer tool over the affected pixels for about 10 minutes.
Keep the pixel fixer window focused on the problematic pixels for approximately 10 minutes.

Pro Tip: Make sure your screen remains active throughout the repair process, so disable any sleep settings in Windows beforehand.
