Hi,
I have just had a bios corruption on my Z97X UD5H motherboard. I *think* it was caused by a Windows 10 SSD failing, which made the BIOS think it had a problem and then I compounded the error by pressing Load Optimal Defaults (my stupid fault).
I managed to get the BIOS back to the Gigabyte F8 version for my MB but my centre monitor out of three stops working when the Mac boots. I have three monitors driven off two 280X cards which have been working fine for two years.
When I get into the BIOS, the centre console works fine, but doesn't work when I start up Sierra. I get the Clover boot menu on the centre console, select the right disk (there's only one disk as I've disconnected everything else), Sierra boots up, the centre console goes dark and stays dark, whilst the two side monitors work fine.
I can Remote Desktop into the Mac from my laptop and get to the centre monitor that way. I've moved the top menu and dock to a side monitor whilst I work out whats happening.
If I check the monitor configuration it shows my three monitors and two graphic cards correctly. I can even move the mouse off the left hand monitor across the (black) centre monitor and it appears on the right hand monitor as if the centre one is working.
If I check display preferences I can see that the three monitors are detected and configured as two portrait monitors on the side with a landscape one in the middle. I can Remote Desktop into the centre monitor from my laptop and see it, I just can't see any output.
The bios configuration appears correct, I actually posted all my BIOS screens some years ago for other people to use

which was really useful. I know the monitor works as I can edit the BIOS. Everything appears plugged in correctly and I know I haven't changed Sierra since the BIOS corruption. I do recall from the screenshots that the BIOS was F6 before and is now F8 but can't believe that is the cause of this. I'm pretty certain I've changed nothing on the Mac side at all, and the Mac was working find before I tried to boot into Windows to correct this debacle.
I've turned off the Internal Graphics Adaptor on the Z97X, I've check the screenshots I posted some years ago and they all match.
Very very confused and would welcome any suggestions as to how to get what has been a reliable system (until now) working again.
My hack has been working for two years now, as per my signature it's a
Z97X UD5H
Dual 280X graphic cards
32GB of memory
Various SSD's though only one is currently plugged in.
Thanks
Rob
