Headless GPU with dGPU

So I have a amd r9 270 with 2 dvi 1 dp and 1 hdmi, but the mobo has hd 4600 graphics with 1 hdmi. If I plug in the hdmi to the igpu and boot it is recognized and boot with those graphics. If I unplug it and boot, I then only see my amd card. I am not currently running a headless platform id for the igpu but I tried previously and it didn't show up under system report. Any ideas?
