Good to know that it behaves as expected. For me, using connector type DP when using DP->DVI adapters does not work. For you, it appears that both DP and HDMI are acceptable connector types when using DP->HDMI adapters. Thank you for checking.
EDIT:
@checotrevi - I may have been too quick to respond. As I posted
here, I needed to reboot a few times to fully observe the effects of my connector type change. I'm not sure about your configuration, but it would be best for you see if conn type HDMI still works after a few power cycles.
