darrenlysenko, I have 2 aura terminals (first for monitor and second for case) and it hurts, if you want to sync case LEDs with MB and use HALO for monitor: asus aura doesn't provide independent control for different terminals (also HALO doesn't give an opportunity to use 2 terminals for one monitor). I hope asus change this soon, because it's annoying (even them aura SDK see two separate devices so, I think, it's not impossible).
And if you want to use HALO for each monitor, you must have separate terminal for each monitor.
English is not my native language, so I'm sorry if I make some mistakes.
