Quick answer
What Color Depth Test tells you
Show browser-reported color and pixel depth with a visual gradient reference.
- Observed here
- Color depth, Pixel depth, Gradient reference.
- How to interpret it
- colorDepth and pixelDepth are values reported by the browser. They do not verify a native 8-bit or 10-bit panel, HDR operation or the full graphics output pipeline.
- Important limit
- Results reflect events and values exposed by this browser.
- Data handling
- Test values are calculated in this browser. Device Test Bench does not store a test result or create a device fingerprint.
Useful next comparison: Compare the reported values with the operating-system and graphics-driver settings, keeping browser privacy restrictions in mind.
Understanding the result
What a result means
colorDepth and pixelDepth are browser-reported values for the current display environment. They do not fully describe panel bit depth, framebuffer precision, HDR capability or whether dithering is active.
Confirm the pattern by repeating color depth. Results reflect events and values exposed by this browser.
How to use this test
- Read the privacy and compatibility notes.
- Start the test and interact only inside the marked test area.
- Repeat the action several times and compare the live indicators.
- Use the troubleshooting section before deciding that hardware is faulty.
What this test checks
- Color depth
- Pixel depth
- Gradient reference
- Browser explanation
What this test cannot check
Results reflect events and values exposed by this browser.
This test does not certify hardware or replace professional inspection.
Reported depth does not fully describe the display panel or HDR pipeline.
Common problems and troubleshooting
Record both values with the gradient reference and operating-system display mode. If HDR or professional color is important, verify with system information and calibrated equipment rather than multiplying browser values.
- Repeat the same observation. Focus the test surface and repeat “Color depth” three times under the same conditions.
- Change one condition. Compare “Pixel depth” after changing only the relevant port, connection, browser setting or application.
- Rule out focus or interception. Close overlays and reserved shortcuts, keep the page visible and confirm that the live indicator changes during the action.
- Keep the result within its limit. Results reflect events and values exposed by this browser.
If the same pattern remains across relevant applications and connections, give the manufacturer or a qualified technician the repeatable observations instead of a guessed fault label.
Browser compatibility
The Screen interface exposes these values widely, but browsers may return conventional values for compatibility. Treat the live fields as environment metadata, not a complete color-pipeline inventory.

Frequently asked questions
Is this Color Depth Test free?
Yes. The test works without an account, download or payment.
Is my test data uploaded?
Test values are calculated in this browser. Device Test Bench does not store a test result or create a device fingerprint.
Does this result prove my hardware is faulty?
No. It shows what the browser can observe. Repeat the test, compare another browser or device, and seek qualified support when the result matters.
