Why can't my MacBook Air run two external monitors from a normal hub?
Reviewer consensus
Apple's M1, M2, and base M3 chips officially support only one external display over USB-C. To drive two or more external monitors on those Macs, reviewers at Macworld and threads on r/mac repeatedly point to docks with DisplayLink built in (such as the Anker Prime DL7400), which uses a software driver to bypass the hardware limit. MacBook Pro models with M-series Pro/Max chips don't have this restriction.
