Why can't I get video on TZ590 & TB560 mining series motherboards after entering HiveOS ?

For the current version of HiveOS it doesn't support Intel integrated CPU graphcis. So if you connect the video output to onboard HDMI or VGA you won't get video.

We advise to connect the video output to the graphcis card installed in PCI-E x16 slot instead.
