CRTC
A CRTC is a display controller provided by your device. It’s primary job is to take pixel data and send it to a connector with the proper resolution and frequencies.
Specific CRTCs can only be attached to connectors that have an encoder it supports. For example, you can have a CRTC that can not output to analog connectors. These are built in hardware limitations.
Each CRTC has a built in plane, which can have a framebuffer attached to it, but they can also use pixel data from other planes to perform hardware compositing.
