we're running a multitrack show on a Mac M2 with Ableton - now we want to upgrade that with two 55" screens and I need a cost-effective but secure solution (these do not necessarily have to be mutually exclusive

Do you any ideas - I've found many USB-C > 2 hdmi Adapters!? However, I am afraid that these are not sufficient in terms of GPU performance. On the other side, I've found many "big solutions" with GPU cards and 4+++ Outputs.... That seemed a bit excessive to me?!?
Thanks and Greetings...
