MacBook Air M2 not connecting to TV via HDMI hub

I am trying to connect my MacBook Air (M2 2022) running Sonoma 14.7.7 to my TV via HDMI. I am using a Vivitar hub with HDMI to USB C to connect to my MacBook Air. When I check the displays settings my Mac, I can see both the Built in Display (my Mac) and the tv display icons. I have arranged them with the Mac icon on top of the TV icon which I thought would mirror the Mac display to my TV. But I am not getting a signal to the TV. I checked my HDMI settings and those are correct. I have restarted my MacBook and granted permission to the Vivitar hub. What else should I be doing?

Fixes: set resolution to 1080p, turn off HDR, mirror displays, power the hub with your Mac charger, try a better HDMI cable, or use a direct USB-C → HDMI cable.

Most of the time, the hub is the weak link, not macOS or the Mac.
