Okay so i have an older all in one  Aspire 5600U and recently decided too use it as a screen for my xbox 
the xbox is connected Via HDMI (it is connected to HDMI IN) but my computer wont allow me to swap my display to HDMI without the computer being turned off which prevents the use of my headset, and as soon as i turn my computer back on the HDMI gets overidden
i have tried changing too my HDMI Via the side controls but the actual HDMI option is greyed out is there another way to change to HDMI?
