i am trying to connect two additional monitors to my new IMAC 24". I am plugging into the two thunderbolt with thunderbolt to HDMI cords. I can connect with either port using either wire to either monitor so i know all components work. It will not recognize whichever one i connect after one is already connected. MACOS 14.4 M3.
iMac (M3, 2023)
Keith is correct, your M3 only supports 1 external display. I know this isn't a solution, but the new M4 based 24" iMacs support up to 2 additional displays:
Display Support
Simultaneously supports full native resolution on the built-in display at 1 billion colors and:
Thunderbolt 4 digital video output

Just an aside. You should update to Sonoma 14.7.1 or Upgrade to Sequoia 15.1.1.
Help IMAC 24" M3 can't connect to two additional monitors at same time
