I could use some help please. I am wanting to set up 3 27" monitor. I do not know if I can use integrated graphics or need a dedicated graphics card. I am also considering possibly 4k 60hz monitors maybe. I do not know what requirements are need from the pc/graphics card. Do I need a dedicated card? Does it need to have 3 hdmi outs? or can it have one hdmi out and then use a splitter? Forgive me I am not very up on these things. Thanks if any one can help.
