YOUR DISPLAY IS THE TEST SURFACE
One screen. Five checks.
Your first five minutes.
Use your usual viewing distance and comfortable brightness. Clean the screen first; a speck of dust can look like a bad pixel.
Start at step 1, or choose where to continue.
Check for marks & stuck pixels
Inspect solid colors for persistent shapes, uneven areas and pixels that stand out.
Check tones & color
Compare neutral whites, near-black details and a smooth grayscale.
Check browser refresh
Measure frame timing with a short, uninterrupted sample.
Check motion clarity
Follow moving shapes and text to look for trails or bright halos.
Check touch, if available
Draw across the surface and try two fingers. No touchscreen? Skip this step.
A practical check.
A clear set of limits.
These tools help you see potential display issues. They do not certify a panel, measure color accuracy or replace a hardware colorimeter.
Your browser, operating system and display settings affect what you see. If something looks wrong, confirm it with another input or device before deciding the panel is faulty.
