<title>Why don’t the default monitor profiles have a calibration expiry?</title>
<p>
The default color profile used for each monitor is generated
automatically based on the display
<link href="https://en.wikipedia.org/wiki/Extended_Display_Identification_Data">
EDID</link> which is stored in a memory chip inside the monitor.
The EDID only gives us a snapshot of the available colors the monitor
was capable of displaying when it was manufactured, and does not
contain much other information for color correction.

<desc>因为 EDID 不能被更新,它没有截止期。</desc>

<note style="tip">
<p>从显示器制造商那里,或者自己创建一个配置文件,会让颜色更准确。</p>
