TV not detected

My TV is not detected by my computer. It's plugged in through an HDMI cable. Under screen resolution after I click detect it states that another display is not detected (I've tried after unplugging my monitor). It's not the cable nor TV's fault because I used both with an old computer running Windows 8 with no problems. I've tried using different ports on the TV (my computer only has one port).
