    Eggy1968 got a reaction from BH1642 in Post Screen/BIOS doesn't display with DisplayPort   
    The issue is that NVidia cards prioritise the ports in this order. DVI -> HDMI - > DP
     
    But depending on your motherboard and UEFI setup you can fix it.
     
    I had a 2 monitor setup. My old 24" monitor on DVI ( in portrait mode to make matters worse!) and a 27" 2K on Display Port connected to my EVGA GTX 970. 
    Motherboard is ASUS Z270-P but I know from others that this will work on other boards.

    NOTE: You must have a UEFI setup, if you have an older legacy non-UEFI setup then this will not work.

    If you don't have a UEFI setup I'm not sure what you can do other than to reinstall Windows in UEFI mode on a clean disk/partition. To be honest I would have done this anyway as it reduces boot time quite a bit.

    The BIOS POST and setup screens would only ever show on the monitor connected via DVI. Apparently the graphics card prioritises the connections in this order 
    DVI -> HDMI -> Display Port

    After a while rotating my head to read the BIOS screen I decided enough was enough. After some research and trial and error I came across a very simple solution.

    Anyway, to the point finally.
    In the motherboard BIOS settings under the BOOT menu (on my board) there is an option called "CSM (Compatibility Support Module)". This is Enabled by default. Changing this to Disabled instantly fixed the issue. You may want to also try 'Auto' in case you have other non-UEFI devices connected but this may not work, it didn't for me.


    Anyway, hope this helps somebody.
