Contrast setting to high (top/left) or too low (bottom/right). Some monitors saturate the bright colors: you can't see the difference between the rightmost few bands (left image). Increasing the contrast setting may help.

2021年11月4日 · To test contrast, we measure the luminance of both white and black using a checkerboard pattern and then calculate the ratio between the two. Luminance is a metric used to measure the amount of light (or intensity) present on a surface and is expressed in cd/m², or candelas per square meter. This is commonly referred to as "nits".

A number of tests will help you evaluate the image quality of your monitor. Even from the first test screens, you can calibrate your monitor by adjusting the brightness, contrast, synchronization phase, sharpness, and gamma correction of the monitor. The tests are best viewed in dim or dark ambient light and in full-screen mode.
