If you have no connected connectors, then you get 1024x768:

imx-drm display-subsystem: No connectors reported connected with modes
[drm] Cannot find any crtc or sizes - going 1024x768

as that's what DRM defaults to when it has no other timing information
available.

I don't see this message booting on a Hummingboard with HDMI
disconnected.
