I think you could give it a try if it using the Standard DP（non-ALT mode） port for output. Since I don't currently have a development board with DP1 output available, I haven't been able to test it yet. As for the Type-C Alternate Mode output, some patches are still required I'll send it with V2 tomorrow or next week. Feel free to let me know if If you encounter any issues。 >
