Instead of changing the fuse and (probably) violating the warranty on the BeagleBone black, if I hack my microHDMI to VGA adapter and give it external power, would it work ? Interestingly, the yellow thing does get incredibly hot and I see nothing past the beaglebone flash screen while boot, that too only after I edited the uEnv.txt file. however the edid info obtained by logging into beaglebone through SSH (putty) shows 1 available resolution 1440x900@60Hz with a different HDMI to VGA adapter 2 options are available 1920x1080 @ 60Hz and another one 1600 something by something. would that be issue of power supply to the HDMI to VGA converter or something else ?
