Monitor pattern and alignment test
Inspect gray steps, gradients, contrast, grids, and related patterns.
Choose a color, inspect the panel, then confirm only what you saw yourself.
Not started
Current color: Red (1/13)
Visual confirmation only — not automatic dead-pixel detection or certification.
Details and limits
How to check
Pick patterns one by one or step forward, using fullscreen to inspect edges. There is no automatic flashing loop.
Limits
Does not prove panel response time, factory calibration, or official color accuracy. Outcomes are user-confirmed.
If something feels wrong
If banding appears, change cable, port, GPU scaling, or a film, then recheck the same pattern.
FAQ
I see bands in the gradient.
Panel, cable, or bit depth can contribute. This tool only helps you look — it does not judge.
The grid looks warped.
Check viewing angle, curvature, and scaling. This is not a geometry certificate.
