IT operating budgets are getting tighter and tighter, so the last thing you need is to be replacing a laptop screen or monitor because of a dead pixel. Today, we look at how to triage a dead pixel monitor to see if you can fix it before throwing it onto the junk pile.
First, you need to figure out if the pixel is stuck, or actually dead. Dead pixels will either be solid black or solid white, depending on the panel. If it's not, then it's likely just stuck.
There are a few different methods to fix a stuck pixel, but this is an easy one to try (at your own risk).
To flush that stuck pixel out, display an all-black image across the screen, and, using a rounded object, like the end of a make-up brush or a sharpie, gently tap on the stuck pixel until it rights itself. Alternatively, you can add light pressure to the area with a damp cloth or tissue.
You want to make sure that you don't do more damage than you started with, so open up a full-screen white image after your work is done to make sure there's no lasting damage.
You can also try using a few different screensavers, YouTube videos or software programs to rectify your issue.
If nothing works, better start fishing out that warranty card and filling out the requisition forms for a new monitor.
