Open a Solid Dark Gray Full Screen

Why Use a Dark Gray Screen?

• Test Mid-to-Low Luminance Uniformity: Dark gray reveals backlight clouding and dirty screen effect that may not be visible on black or mid-gray.
• Find Stuck Pixels: Both bright stuck pixels and dark dead pixels can be spotted on a dark gray background.
• Evaluate Grayscale Tracking: It helps check if a display maintains neutral gray at lower brightness levels.
• Check for Banding: Dark gray is a good starting point before testing gradients for banding artifacts.
• Dim Ambient Light: Dark gray offers a very low, neutral light for use in dark environments without color cast.

The Role of Dark Gray in Display Calibration

Dark gray is a critical test pattern for calibrators. It falls in the range where many LCD panels exhibit the most backlight bleed and clouding. Checking dark gray can help you decide if a monitor's uniformity is acceptable for dark-room movie watching.

For users who prefer dark mode, a dark gray screen can represent the typical background shade of many apps and websites, giving a realistic preview of how content will look.
