Pixel Tester

Pixel Tester is a handy little app for Mac that helps you check all your connected displays for any dead pixels. If you've ever noticed a stubborn dot on your screen that just won't light up, this tool can help you find it. Depending on the manufacturer's rules about faulty pixels, spotting these issues might even let you ask for a replacement!

Easy to Use Testing Process

Color Patterns at Your Fingertips

When you move your cursor, Pixel Tester shows different colors based on where your pointer is located. For example, if your cursor is in the bottom area of the screen, you'll see bright red, blue, or green colors; while at the top, you'll see pure white. This makes it really easy to figure out if there are any dead spots.
