My hopes of using a cheap vga monitor drifted away when my HDMI to VGA converter shut down within a few seconds. A peek at the BeagleBoneBlack schematic shows a 100 ma resettable fuse guarding the mini hdmi power pin. It's the yellow thing that looks like a ceramic capacitor. Luckily it's not surface mounted, so is relatively easy to replace with a 200 ma fuse -- digikey#RXEF020-ND. Now 35 cents and ten minutes work later, all is well. I do use a powered USB hub so as not to overload the BB power regulator -- the reason, is suppose, why the designers used the fuse.
