I think there's confusion.
Your TV probably has 4 HDMI *inputs*, not outputs. Try it out. Plug in an HDMI from your computer into the TV then switch to the source on the TV and see if it displays. It should work.
Just know that if you want to display a 4K HDR output to the TV, the HDMI cable must be HDMI 2.0b compatible, otherwise it will cause stutter. 2.0b was released in 2016.
