Dead Pixel, Color, Motion, and Refresh Rate Test

Use controlled fullscreen patterns and measured browser presentation timing to separate panel symptoms from scaling, settings, cables, and graphics issues.

Diagnostic result

Confirm each mode individually (0/7)

MeterSee requires a separate manual result for every visual mode. Pixel defects, banding, black level, ghosting, sharpness, and uniformity remain observations affected by panel settings and the viewing environment.

0/7 modes confirmed
1/6 solid fields viewed
Refresh not measured
No confirmed issues

Use the panel's native resolution, disable night-light modes, allow the display to warm up, and inspect in controlled ambient light. Refresh timing is inferred from visible-tab animation callbacks and may be affected by VRR, browser compositing, power saving, or system load.

After the test

Interpret the pattern before replacing a monitor.

MeterSee provides known visual stimuli. The viewer records what is visible, while refresh timing is reported as a browser estimate rather than a laboratory panel measurement.

Your resultPossible causesTroubleshooting steps

Dot remains on every solid fieldPossible dead pixel, stuck subpixel, or surface debris

Clean the powered-off panel, repeat RGB fields, and compare a photograph before contacting the manufacturer.

Gradients show steps or color tintPanel bit depth, GPU output, color profile, or compression

Use native resolution, disable night modes and HDR temporarily, then compare another cable and source.

Moving edge leaves a colored trailPixel response, overdrive, or display processing

Repeat at the panel's native refresh rate and compare overdrive settings without treating a browser pattern as a response-time instrument.

Display patterns and timing

How this test works

Solid colors, gradients, text, and motion patterns support visual inspection. Animation callback intervals estimate browser presentation timing.

What this cannot establish

The page cannot see defective pixels or certify physical refresh rate, color accuracy, or response time. Use native resolution and inspect the panel yourself. Do not press or rub a suspect pixel.

Recheck before replacing hardware

Change one variable at a time, repeat under the same conditions, and compare with the operating system or the affected application. An unavailable reading is not a pass.
