Inspect colors, light and fine detail.
Choose a still pattern and record what you see. Use Save as checked when you finish inspecting it.
All patterns stay available. A task suggests a useful order and follow-up.
01Choose your pattern
Use comfortable brightness and your usual viewing position.
Preview ready. Choose a pattern, then open the larger view.
Use the arrow keys while the pattern is focused. Press H or tap the pattern to restore hidden controls. With marking on, a tap adds a point and restores hidden controls. Escape exits.
Your inspection record
Seen means opened in the larger view. Checked means you saved an observation. Skipped means you chose not to decide. The remaining patterns were not visited.
Review all patterns and revisit
Suggested next steps
This record contains your visual observations and approximate locations on the pattern. Keep the settings and repeatable steps when asking the manufacturer to assess a concern.
Notes stay in this page until reset, reload or close. An explicit language switch can carry them once in this browser tab for up to two minutes. They are not put in a URL or sent to us. Downloaded files stay on your device until you delete them.
Use the still patterns to inspect a spot, uneven light or a retained shape. Choose a guided task for a suggested route, or select patterns freely. Each image stays still until you change it. Add observations as you go, then review and download the local report.
Set up a useful view
Put the browser on the display you want to inspect. Use comfortable brightness and your normal viewing position. Note the room lighting, picture mode and whether HDR is active. Check surface dust and reflections first; follow the display maker’s cleaning instructions.
Request fullscreen for a larger view. If the browser does not allow it, use the expanded page area; browser bars and other parts of the display remain outside that view. Use the display’s native resolution and start at 100% browser zoom for fine-pattern checks. System scaling and pixel ratio still affect the relationship between a pattern pixel and a physical panel pixel.
Choose the pattern for your question
| Pattern | Useful observation |
|---|---|
| Black and white | Look for a small contrasting spot that stays in the same screen location. Compare larger light areas from your normal position. |
| Red, green and blue | Revisit a suspected spot on each color. Record which backgrounds reveal it. |
| 25%, 50% and 75% gray | Compare center, edges and corners for lighter, darker or tinted areas, or a recognizable retained shape. These percentages describe RGB pattern levels. |
| Gray and color gradients | Look across the transition for bands or sudden steps. Keep the browser and picture mode consistent. |
| Near-black steps | Look for differences between the dark patches and the black reference. Record which steps merge in your current lighting. |
| Near-white steps | Look for differences between the light patches and the white reference. Note where separate patches appear to merge. |
| Sharpness and checkerboard reference | Look for clear repeated detail, halos or uneven-looking bands. Compare at native resolution and 100% browser zoom before changing sharpness. |
Record what you checked
Opening a pattern records a visit. Explicitly record the outcome when you have checked it; you can also skip a pattern. The report keeps visited, checked, skipped and unvisited patterns separate. Use Save as checked to add your observation to the checked count.
If something stands out, add an observation with its approximate location and optional notes about the pattern or settings. Revisit the field to compare, correct or remove an observation. A location mark gives you an approximate reference on the displayed pattern.
Review the summary before finishing, especially if you stop early. The report separates the patterns visited and outcomes you recorded. Download it to keep a copy outside the working session. Read how observations and language switching are handled.
Compare picture settings with dark and light steps
Write down a setting before changing it. Compare one reversible adjustment at a time, then revisit both dark and light steps and ordinary content. Record what becomes easier to distinguish and whether something else is lost. The darkest or lightest steps need not all be visible in every mode or room.
Fine checkerboards can change appearance when zoom, scaling or image processing resamples them. Check those conditions before treating an uneven pattern as a panel fault. The EIZO visual test also notes that browser color management affects web patterns.
These patterns help you compare settings by eye. For measured luminance, contrast, color accuracy or a display profile, use suitable calibration equipment. The ICC calibration guide explains the instrument-based calibration and profiling workflow.
Pattern controls and related checks
Use Previous and Next, the left and right arrow keys, or select a pattern directly. Hide the controls with the button or H. Use the restore control or H to bring them back. End the larger view with its end control or Escape, then review your observations.
For bright corners, follow IPS glow vs backlight bleed. For a recognizable outline, follow image retention vs burn-in. The new-monitor checklist helps document a repeatable concern. Missed finger input belongs in the touchscreen test; moving trails belong in the motion comparison.
