Not every motherboard BIOS allows to use both iGPU and dGPU to be used at the same time, or if they do, special software installation and/or configuration may be required. First check in BIOS to ensure you don't find a setting engaged that disallows your desire. It may be all that's required is using xrandr, or a GUI tool that employs it (e.g. arandr), to appropriately locate and orient the errant display, e.g.: xrandr --output HDMI-1 --right-of DP-1 --rotate normal -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
