<title>Why don't the default monitor profiles have a calibration expiry?</title>
18
The default color profile used for each monitor is generated
19
automatically based on the display EDID which is stored in a memory
20
chip inside the monitor.
21
The EDID only gives us a snapshot of the available colors the monitor
22
was capable of displaying when it was manufactured, and does not
23
contain much other information for color correction.
27
<desc>As the EDID cannot be updated, it has no expiry date.</desc>

Getting a profile from the monitor vendor or creating a profile
34
yourself would lead to more accurate color correction.
