Connect MacBook Pro to tv via cable and adapter.

Will a mini display with HDMI port connected to my AV adapter work with my new smart TV? I am hoping to connect my early 2015 MacBook Pro to this new tv. The adapter and HDMI cable would not work with either my iPad Air2 or iPhone 8. I am running Catalina 10.15 on the MacBook Pro. I need a separate adapter for the MacBook Pro and don't want to buy it unless it will work.
