About Contrast Ratio Test
Check how deep blacks and bright whites look side by side and set contrast without clipping.
Contrast ratio is the difference between the brightest white and the darkest black a screen can show at the same time. A high contrast ratio gives deep, punchy images, while a low one makes dark scenes look gray and flat. IPS monitors usually sit around 1000:1, VA panels reach 3000:1 or more, and OLED screens reach near infinite contrast because their pixels turn fully off.
How To Test Contrast
Use a checkerboard of black and white squares to judge in-screen contrast, and white bar patterns to set the contrast control. Raise contrast until the brightest bars start to merge, then lower it a step so every bar stays separate. Then check a black field in a dark room to see how gray the blacks really are.
Contrast Ratio Explained
- Static contrast: measured with black and white on screen together.
- Dynamic contrast: a marketing figure that changes backlight over time.
- ANSI contrast: measured with a checkerboard, the toughest real world test.
