A:Answer the pc GRPAHICS card has a display output and hdmi output, id recommend using the display out to a monitor with a display port in something 144hz, there is one more adtional hdmi on the motherboard but dont expect that one to pushing your games out to you the way it should because its not coming straight from the grapics cards.
i currently use both ports on the graphics card. the dispay for my monitor and the hdmi to go to my Elgato capture card to send the game footage over to the pc/monitor next to me to have it streamed from there.
1-pc to play the games
1-to host the stream
