When you get a new monitor or laptop, it is good to see if there are any stuck or dead pixels. The easiest way to find problem pixels is to display solid colors and look over the screen. You have to look at it yourself since the software can’t actually detect if there is a hardware problem with the monitor.

This free software displays solid colors for you to find dead pixels.

For Windows – Dead Pixel Tester

What if you have dead pixels?

Dead pixels can sometimes be fixed by gently massaging them in a circular motion. In my experience, this works about 20% of the time. Most manufacturers will accept returns if you have a certain number of dead pixels.
