Display a Deep Maroon Screen

Why Use a Maroon Screen?

• Test Dark Red Channel: Maroon pushes red at half brightness, revealing how the display handles dark red gradients and shadow detail.
• Find Stuck Red Subpixels: Defective red subpixels that only fail at lower intensities become visible.
• Check Backlight Bleed: A dark maroon screen can show light leakage similar to a black screen but with a warm cast.
• Evaluate Warm Dark Uniformity: Clouding or uneven patches in dark warm colors are easier to see on maroon.
• Dim Warm Night Light: Maroon offers a very low, warm glow for nighttime use without sharp brightness.

How to Use

1. Start: Click the button or tap the preview to open the full maroon screen.
2. Inspect: Look for dead pixels, backlight clouding, or uneven dark red patches.
3. Exit: Press ESC or click anywhere to close.

Benefits of the Maroon Screen Tool

• Free Online Access: No installation needed.

Using Maroon for Display Diagnostics

Maroon is a deep, subdued red that is often found in dark wood tones, autumn scenes, and certain UI themes. Testing with a maroon screen can catch red subpixel weaknesses that only appear below maximum brightness.

Because of its darkness, maroon is also useful for checking overall screen uniformity in conditions similar to watching dimly lit movie scenes.
