HDMI is a bit difficult at the moment as there is an issue with the Blackice Mx HDMI wiring, and none of the current retro-computing cores use HDMI. I did get the Nintendo Entertainment System working with an iCEBreaker HDMI Pmod on the iCEBreaker board, and that would probably also work on the Blackice Mx board.
