I have an aspire Z3-715. I plugged in my Xbox One to the pc. It works fine but when i unplug my Xbox one HDMI, my PC wont start at all. Pressing the power button doesnt work and the monitor/pc will only " turn on" when my xbox is on and the HDMI is plugged in. When im on that i can click the monitor setting and change to PC mode but then i just get " no PC signal". So basically the only way my monitor/pc is on is when my xbox is on.
