Hey, Thanks I have the same with Sierra it worked without any problem.
Your main screen only have HDMI or also dvi ? If it hase dvi maybe you can try to connect your hdmi to a tv and the dvi to your main screen. If you can get to the installer it should work.
High Sierra installed without problems for me already. Ethernet works and audio, too.
I can use it with a single monitor, but if I attach a second it just mirrors the first one and is tainted in green.
One thing I'm going to try is switching from VGA->DVI to VGA->DP. Will report back with the results.
