For example, I've an evaluation board, whre I connect in one side an HDMI input signal an in the other side a DP monitor, the driver only configures the chip and waits for different events (cable plug, cable unplug, etc ..)

But what if the chip is connected to a display controller, for instance to the HDMI output of an SoC ? Is that a use case for the hardware ?
