if you get the matrix v2 then you simply have switches to help with boot times.
the main thing is trial end error with the long wire. mines at around 40cm and boots within 30sec most of the time.
your broken hdmi "may" cause an issue with rgh if the hana chip is damaged as that is what the rgh relies upon but hopefully you should be fine
i use the matrixv2 in my slim, i havent done any older rgh ones, just jtags
