(ONLY ANSWER IF YOU KNOW) So I want to play call of duty MW on my my pc to my 4k 120hz tv using a hdmi cable, do i just need any type of hdmi cable or do i need to get a 4k 120hz hdmi cable? I don't know how I'd do that exactly. In other words, how do i use my TV as my MONITOR for my pc to play games. I'd assume that you use a hdmi cable like plugging in a xbox or playstation. thanks, Rodger! :)
