Dead Pixel Test for iPad

Flashing primary colors in 4:3 ratio for dead, hot or stuck pixel testing on iPad.
First half flashes a new color each second, second half every two seconds.

How To:
Begin by ensuring your screen is clean, as dust or dirt can be mistaken for dead pixels. Use a soft cloth suitable for your screen type to gently wipe it.

Next, watch this video in full screen. It displays a repeating color pattern for you to be able to test your screen.

Carefully examine the screen for any pixel issues: look for pixels that are a different color from the rest of the screen or completely black.
– A consistently black pixel indicates a dead pixel.
– A pixel that does not change color when the screen color changes is referred to as a stuck pixel.

Pixels are actually made up of single color sub-pixels – red, green, and blue – that combine to create all colors in the possible spectrum. A dead pixel occurs when all three sub-pixels fail, resulting in a black dot. A stuck pixel happens when one or more sub-pixels are not functioning correctly, causing the pixel to always display a specific color.

After the test, assess whether you have an excessive number of dead pixels. Manufacturer policies generally allow around 5 or more dead pixels, though Apple’s specific threshold is not disclosed and may be lower. If you find an excessive number of dead or stuck pixels, or if they are significantly distracting, check with the Apple Store (or your retailer) to see if a replacement is covered. Having AppleCare+ can of course be beneficial in this situation.

The screen seems fine in the video but when I was working on procreate, there seemed to be a few pixel dots appearing(white and red dots mainly) I don’t use a lot of pressure with the pen. Maybe because I worked in a black ground I could see the pixels? But haven’t seen those before even and It didn’t happen after sometime. Should I be concerned 😢
