How to Use the Screen Test
Select a pattern from the test buttons or use Previous and Next. Use Full Screen for a larger testing area. The color and pixel tests can help identify pixels that look different from surrounding pixels. Gradient and grayscale tests can reveal visible transitions or banding. The motion test is useful for visually inspecting motion handling.
⬛ Dead Pixel Test
Use solid colors and pixel patterns to inspect individual pixels.
🌈 Color Test
Test primary RGB colors, white, black and color bars.
🌗 Grayscale
Inspect multiple gray levels and brightness transitions.
📈 Gradient Test
Look for visible steps or banding in smooth black-to-white transitions.
🔲 Sharpness Test
Fine grids and lines can be used to inspect display sharpness.
💡 OLED Test
Display high-contrast patterns that can be used for visual inspection of image retention.
🏃 Motion Test
Moving objects provide a simple visual motion-handling test.
📐 Pixel Patterns
Test 1px, 2px, 5px and 10px patterns for detailed pixel inspection.
⛶ Full Screen
Expand the test to your entire display for easier inspection.
