3rd Monitor not being recognized on my MacBook Pro (2015)

I have a dual monitor setup using both of the thunderbolt ports. The third monitor that I want to add that is not being recognized is HDMI and I have it plugged into the built in HDMI port. It's just blank and not being detected by the computer. What do I need to do to get the computer to recognize the third monitor?
