<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.
</p>
<note style="tip">
<p>
Getting a profile from the monitor vendor or creating a profile
yourself would lead to more accurate color correction.
