A monitor is typically connected to its host computer via DisplayPort, HDMI, USB-C, DVI, or VGA.

Companies that are licensed by HDMI LA are known as HDMI Adopters. [88] DVI is the only interface that does not require a license for interfacing HDMI. [citation needed]
Some VGA connectors in personal computers provided a basic form of identification by connecting one, two or three pins to ground, but this coding was not standardized. This problem is solved by EDID and DDC, as it enables the display to send information to the graphics card it is connected to.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
HDMI lacks VGA compatibility and does not include analog signals. DVI is limited to the RGB color model while HDMI also supports YCbCr 4:4:4 and YCbCr 4:2:2 color spaces, which are generally not used for computer graphics.
