I use my PC as a home theater pc so I have my display port connected to my 4K tv and an HDMI connect to my audio system for sound obviously. It has always defaulted to a multi screen setup in the past, however it never bothered me since it was always the same whether I was looking at the hdmi feed or the disport feed. Ever since I upgraded to windows 10 though if I have both the HDMI and the displayport connected the HDMI has screen one on it and the display port only carries screen two. Is there any way I can disable this feature? It really sucks I cant watch my 4K content.
