I updated the bios on my Z390-F this morning and since then both POST and BIOS do not show on monitors plugged into GPU (MSI Ventus 3080). System boots fine and once windows login screen apears display is fine however prior to this I get no display. Plugging a monitor into onboard will show POST and BIOS ok but not a suitable long term option as don't want to be swapping cables around each time I want to change a BIOS setting especially now as I need to redo all my OC settings.

Anyone have any ideas? Tried searching but just end up with 101 results about PCs not posting.

Yeah find it weird only change was BIOS update, I am guessing I am missing a setting somewhere as everything was reset to default but just cant see it.

On board video is disabled in BIOS, never been used prior.

I have 3 monitors, 2 are plugged into display port and one into HDMI. None show a signal.

Found the issue... turns out I am an idiot!

wolfy you pointed me in right direct, have a Valve index HMD which I normally don't have plugged in. Unplugging that has sorted it out. Weird though as it must have been plugged in as issue happened straight after update and I did the update from within the BIOS. Also strange it shows on onboard with HMD plugged in.

Fixed now though with thanks.
