Viewing Angle Test · At a glance
Quick answer: Compare stable color fields from different viewing positions. Brightness and tint shifts reveal off-axis appearance under the current setup.
Viewing Angle Test
The test loads when you open it. Device access is requested only after you choose to start.
Detailed guide
How to use this tool
- Keep a gray or saturated field unchanged and move your head to different positions.
- Return to center between comparisons.

How it works and what the result means
These are visual inspection patterns. The page cannot read individual panel pixels, measure nits or contrast ratio, diagnose a panel automatically, or repair dead pixels.
Reading the result
Brightness and tint shifts reveal off-axis appearance under the current setup. They do not measure a standardized viewing-angle specification.
Worked example and assumptions
Steady gray and saturated color fields
Keep the image unchanged and move your viewing position. Observe brightness and tint shifts; do not confuse off-axis effects with a changing source image.
Keep the image unchanged and move your viewing position. Observe brightness and tint shifts; do not confuse off-axis effects with a changing source image.
What to check next
Keep camera exposure and screen brightness fixed if recording. Reflections can change with position and resemble a panel shift.
Use native screen resolution and 100% browser zoom for fine patterns. Disable adaptive brightness for comparisons. PWM inspection needs an external camera; banding can also be a camera artifact.
Frequently asked questions
Can I compare angles from different photos?
Only cautiously. Different exposure, lens position and lighting can dominate the image. A controlled viewing setup is needed for a fair comparison.
How do I start the Viewing Angle Test?
Choose a pattern and open fullscreen. Inspect the entire panel, then click to cycle patterns. Press Escape to leave fullscreen.
Does this tool require a download or an account?
No. Open the interactive tool above in a modern browser. The instructions and explanations are available even with JavaScript disabled; running a test needs JavaScript.
Why can two attempts give different results?
Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
