The OS has more control about the display pipeline used for the HDMI output on M2 based devices. The HDMI output is driven by an integrated DisplayPort to HDMI converter (Parade PS190). The DPTX phy is now controlled by the OS and no longer by firmware running on the display co-processor. This allows using the second display controller on the second USB type-c port or tunneling 2 DisplayPort connections over USB4/Thunderbolt. The m1n1 bootloader uses the second display controller to drive the HDMI output. Adjust for this difference compared to the notebooks as well.
