Solid colors
White and RGB screens expose dark or incorrectly colored pixels. Black reveals hot pixels, glow and edge bleed.

MacBook Screen Test for Dead Pixels, Bleed and Color
Check your MacBook Air or MacBook Pro display with fullscreen colors, gradients and motion patterns. Find dead pixels, uneven brightness, backlight bleed and banding before your return or warranty window closes.
No install or upload Retina and XDR ready
Interactive display test
Test Your MacBook Screen in Fullscreen
Click any tile to begin. Use the arrow keys or Space to move between tests, P for auto-play, I for display information and Esc to leave fullscreen.
Solid Color Test
Check for dead pixels, bright spots, and color uniformity
Gradient Test
Check for banding, gamma, and smooth transitions
Pattern Test
Check geometry, sharpness, and pixel alignment
Brightness & Gamma
Check the gray ramp, posterization, and shadow / highlight detail
Contrast Test
Check full black/white swing and fine 1px transitions
Backlight Uniformity
Check clouding, backlight bleed, vignette, and IPS glow
Sharpness / Text
Check text clarity, color fringing, and scaling
Motion / Ghosting
Check pixel response time and motion blur
Flicker / Strobe
Check flicker and refresh-rate artifacts
Prepare Your MacBook for an Accurate Test
- 1
Clean and warm up
Use a dry microfiber cloth, then let the display run for 10-15 minutes.
- 2
Disable display adjustments
Temporarily turn off True Tone, Night Shift and automatic brightness in System Settings.
- 3
Use fullscreen mode
Launch each pattern fullscreen and check the panel from the center, edges and corners.
- 4
Repeat at two brightness levels
Inspect once near 50% brightness and again near maximum to reveal different uniformity issues.
What Each Test Reveals
Gradients and grayscale
Look for abrupt steps, tinted gray areas or lost shadow detail instead of a smooth transition.
Patterns and text
Fine grids and text help identify scaling softness, image retention and inconsistent sharpness.
Motion and flicker
Moving shapes reveal smearing and response artifacts. Compare results at your MacBook's available refresh rates.
Tip for Liquid Retina XDR models: local dimming can make bright objects on a black background appear to glow slightly. Compare several patterns before treating blooming as a defect, and document persistent issues with a camera for Apple Support.

MacBook Screen Test FAQ
How do I test my MacBook screen for dead pixels?
Clean the display, open this page in Safari or Chrome, launch each solid-color test in fullscreen and inspect the entire panel. White, black, red, green and blue screens make dead, stuck and hot pixels easier to identify.
Does this test work on Retina and Liquid Retina XDR displays?
Yes. The test runs at the browser's fullscreen resolution and works with Retina, Liquid Retina and Liquid Retina XDR MacBook displays. It requires no download or color-profile change.
Should True Tone and Night Shift be turned off?
Turn off True Tone, Night Shift and automatic brightness while checking color, grayscale and uniformity. You can leave them on for a second pass that reflects your normal daily setup.
Can a browser test fix a dead pixel?
A truly dead pixel is a hardware defect and normally cannot be repaired by software. A stuck subpixel may sometimes recover after controlled color cycling, but persistent defects should be documented for service or warranty support.
