White Screen vs. Red screen Tests: Which is Right for You?
3 min read


Screen issues can be a real headache, whether it's dead pixels, uneven brightness, or color irregularities. That's where screen tests come in handy. Two common options are the white screen test and the red screen test, each serving a unique purpose. In this article, we'll delve deeper into these tests, helping you understand the differences and decide which one is best for your situation.

The White Screen Test:

The white-screen test does exactly what its name suggests. It displays a plain white image on your screen, and it's most commonly used for straightforward checks. Here's what it's all about:

  1. Spotting Dead Pixels: One of its primary purposes is to help you find dead pixels. Dead pixels are those pesky black dots that show up on the bright white background. When you notice them.
  2. Brightness and uniformity: The white screen is perfect for assessing the overall brightness and uniformity of your screen. Any variations in brightness or uneven color across the screen become evident against the white background.

The Red Screen Test:

In contrast, the red screen test involves displaying a bright red image. This specialized test is designed to uncover a wider range of issues compared to the white-screen test. Here's what you need to know about the red-screen test:

  1. Checking for Color Banding: The full red screen test can help identify color banding, which appears as distinct bands of different shades within the red background. This issue can negatively impact the overall viewing experience, particularly when it comes to graphics and multimedia content.
  2. Evaluating Color Accuracy: Assessing color accuracy is another advantage of the red screen test. You can use it to determine if your screen reproduces red tones accurately. Any significant deviations from the desired red hue can affect the visual quality of images and videos.
  3. Detecting Stuck Pixels: Stuck pixels are different from dead pixels, as they remain a fixed color other than black. The red screen test can help you identify stuck pixels that appear as bright red dots on the red background.
  1. Evaluating Color Vibrancy: Assessing color vibrancy is another advantage of the red screen test. You can check if your screen displays the red color with the vibrancy and intensity it should have. Dull or faded colors would indicate a display issue.


The choice between the white-screen and red-screen tests ultimately depends on your needs. If you're looking for a quick and basic check for dead pixels and general screen brightness, the white-screen test is sufficient. However, if you desire a more comprehensive assessment, including color consistency, screen bleeding, burn-in, and flickering detection, then the red screen test is the way to go.

To ensure a thorough evaluation of your device's display, consider using both tests. Regularly performing these assessments, particularly when you first acquire a new device, will help you maintain a high-quality visual experience. So, whether you opt for white or red, your screen will continue to shine at its best.
