I successfully downloaded and installed big sur, but after system asked me to restart it never appeared with a display.
after an hour I tried a restart and after that SMC and NVRAM resets, even tried usb-c hdmi dongle for display instead of hdmi port, nothing seems to work.
any ideas...?
update: I hooked it up with hd tv and it worked, what could be failing in making my actual monitor work as before and how to fix it?
