edid

The edid command is used on the Makito X DVI to set the DVI-D preferred resolution advertised as part of the HDMI EDID (Extended Display Identification Data), so that connected devices do not scale their output resolutions to match the current Makito X DVI default (1080p). The current default may cause image distortion issues when computer graphics resolutions are encoded for some third party equipment.

Tip

This is useful because some computer video cards do not allow users to specify a resolution other than the advertised preferred one. If you have trouble getting your computer to send the proper graphic resolution to the Makito X, forcing the EDID to advertise that resolution as its preferred input format is likely to remedy that situation.

Note

EDID (Extended Display Identification Data) is a data structure provided by a digital display to communicate its capabilities to a video source device.
