Controllo online di pixel difettosi e subpixel bloccati
Cycle black, white and primary-color fields to separate a dark dead pixel from a subpixel that is locked on red, green or blue.
Test dello schermo online per pixel difettosi, uniformità OLED e movimento del monitor
Uno spazio nel browser per controllare pixel, colori, gradienti, nitidezza e movimento su monitor, telefoni, tablet e TV.
Come eseguire il test
Use Left or Up to go back; use Right, Down or Space to continue.
Move the pointer to the bottom edge in fullscreen to show the controls.
After the final pattern, the next step closes the fullscreen view.
Choose any pattern to open it in fullscreen.

Test a tinta unita
Inspect pixels, bright spots and panel uniformity.
Test dei gradienti
Review banding, gamma and smooth transitions.
Test dei pattern
Check geometry, sharpness and pixel alignment.
Pattern online per testare pixel, colori e uniformità dello schermo
Start with a full-color sweep, move through grayscale and gradients, then use geometry and motion patterns to isolate the kind of display problem you are seeing.
Controllo della risoluzione nativa e della nitidezza
Use the grid and text patterns at the panel's native resolution to spot scaling, chromatic fringing and softened one-pixel lines.
Controllo a schermo intero di monitor, telefono e TV
Open every pattern without browser chrome so edge glow, tint shifts and small uniformity changes are easier to compare.
Quando testare un monitor, un telefono o una TV
Use the patterns before a return window closes, after moving a display to a new setup, or whenever a panel looks uneven in everyday content.
Controllo di pixel e uniformità di un monitor nuovo
PopularRun the black, white and gray fields before accepting a new monitor or television, while a return or exchange is still simple.
Controllo dell’uniformità dello schermo di telefono e tablet
Use clean fields to look for tint, pressure marks, uneven brightness and pixels that remain visible against a matching color.
Controllo di colore e scala di grigi per foto e video
ProCompare RGB channels, grayscale steps and neutral fields before trusting a display for color-sensitive editing; this is a visual check, not a colorimeter measurement.
Controllo di ghosting e motion blur nei giochi
Use the moving blocks and scrolling pattern to compare trailing, judder and overdrive halos at the refresh rate you actually play or watch.
Domande su pixel difettosi, burn-in OLED e controllo del colore
These practical answers explain what a browser test can reveal, what it cannot measure, and how to make a visual inspection repeatable.
Come verificare online pixel difettosi e subpixel bloccati su un monitor?
Open the solid-color section, view black, white, red, green and blue at fullscreen, and inspect the panel from a normal distance before checking suspicious spots up close.
Un test online può rilevare burn-in OLED o problemi di uniformità dei grigi?
It can reveal visible retention, tint, banding and dirty-screen effects on gray fields, but it cannot prove permanent burn-in or replace a calibrated measurement device.
Quali impostazioni usare per un test dello schermo affidabile?
Warm the panel for a few minutes, use its native resolution, disable adaptive brightness and compare the same pattern at a comfortable brightness in both normal and dim room light.
Il test funziona su telefoni, TV e monitor OLED?
Yes. The patterns run in modern browsers on phones, tablets, TVs, OLED monitors and LCD panels. Fullscreen and native resolution make the visual comparison more useful.
