I've got an old NUC with Intel vPro support which allows out-of-band management including remote desktop, like you'd expect from drac/ilo on a dedicated server.

I've got an old NUC with Intel vPro support which allows out-of-band management including remote desktop, like you'd expect from drac/ilo on a dedicated server. Headless box living in a cupboard, sounded perfect. It turns out that if the BIOS doesn't detect a monitor connected it puts the graphics card into power saving, so if you remote connect you get a blank screen rendering the whole thing useless. Took a while to work out what was going on too, I assumed firmware or networking issue to start. I also ended up buying a few of these dongles before finding one that actually worked.
