Comprehensive Monitor Health Check Guide

Your monitor is your window to the digital world. Use the dashboard above to select specific tests or run the full suite.

1. Test Pattern & Geometry

Check geometry and resolution. Circles should be perfectly round.

2. Dead Pixel Check

Cycle through primary colors to spot dead pixels (black dots) or stuck pixels (colored dots).

3. Uniformity & Backlight Bleed

Use gray screens to check if brightness is consistent across the panel.

4. Gamma & Gradients

Verify color smoothness. Gradients should not have visible bands.

5. Response Time & Ghosting

Move objects fast to check for trails (ghosting), critical for gaming.

6. Refresh Rate (Hz)

Measures the real browser frame rate (e.g., 60Hz, 144Hz).

7. Local Dimming

Tests Mini-LED/OLED zones for blooming (halo effect around bright objects).

8. Stuck Pixel Fixer

An experimental utility that flashes random colors at high speed to try and unstuck pixels. (Caution: Flashing lights).
