Penjelasan teknis
The page reads window.screen properties and visualViewport dimensions. CSS pixels differ from physical pixels, so devicePixelRatio is shown separately. Browser privacy protections may reduce precision or hide values.
Dead-pixel patterns are solid colours that make defective subpixels easier to see. A screen recording captures the browser compositor output, not the physical panel.
Pemecahan masalah
Resolution looks lower than expected
Browser zoom, display scaling, and privacy protections affect reported CSS values. Physical resolution may not be exposed.
Full-screen does not open
The Fullscreen API requires a user gesture and may be blocked by embedded browsers.
Screen recording is unavailable
Some browsers or managed devices disable getDisplayMedia.
Colours look inaccurate
Colour profiles and HDR modes affect rendering. This tool cannot calibrate a display.
