About this tag
This tag covers discussions about EDID corruption, a common cause of external monitor detection failures in Windows 10 and Windows 11. EDID (Extended Display Identification Data) is the data block a monitor sends to the graphics card to describe its capabilities. When this data becomes corrupted, Windows may fail to detect the monitor, show incorrect resolutions, or display a black screen.

The tag also covers safe cleanup procedures to avoid repeating the same issues.
