Is the video mirrored, or does it just go to one of > the instances? IIRC they are not connected to the same outputs, there is one for MIPI DSI, one for LVDS displays and one for HDMI. The LVDS instance is connected to a bridge (called LDB) which may join or mirror two LVDS displays. Thanks, Miqu=C3=A8l
