불량 픽셀과 고정 서브픽셀 온라인 검사
Cycle black, white and primary-color fields to separate a dark dead pixel from a subpixel that is locked on red, green or blue.

패턴 테스트
Check geometry, sharpness and pixel alignment.
픽셀·색상·화면 균일도를 위한 온라인 테스트 패턴
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.
원본 해상도와 화면 선명도 확인
Use the grid and text patterns at the panel's native resolution to spot scaling, chromatic fringing and softened one-pixel lines.
모니터·휴대폰·TV 전체 화면 검사
Open every pattern without browser chrome so edge glow, tint shifts and small uniformity changes are easier to compare.
모니터·휴대폰·TV를 화면 테스트해야 하는 경우
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.
새 모니터의 불량 픽셀과 균일도 확인
PopularRun the black, white and gray fields before accepting a new monitor or television, while a return or exchange is still simple.
휴대폰과 태블릿 화면 균일도 확인
Use clean fields to look for tint, pressure marks, uneven brightness and pixels that remain visible against a matching color.
사진·영상 편집을 위한 색상과 그레이스케일 확인
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.
게임용 모니터 잔상과 모션 블러 확인
Use the moving blocks and scrolling pattern to compare trailing, judder and overdrive halos at the refresh rate you actually play or watch.
불량 픽셀·OLED 번인·색상 검사를 위한 화면 테스트 질문
These practical answers explain what a browser test can reveal, what it cannot measure, and how to make a visual inspection repeatable.
온라인으로 모니터의 불량 픽셀과 고정 서브픽셀을 확인하는 방법은 무엇인가요?
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.
온라인 화면 테스트로 OLED 번인이나 그레이 균일도 문제를 알 수 있나요?
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.
신뢰할 수 있는 화면 테스트를 위해 어떤 설정을 사용해야 하나요?
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.
화면 테스트를 휴대폰, TV와 OLED 모니터에서도 사용할 수 있나요?
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.
