How can I get hub that runs 2 external monitors via HDMI in extended mode on MacBook Air M4?

If you're using a MacBook Air with the Apple M4 chip (2025 model), it officially supports only one native external display via Thunderbolt/USB‑4—even though the MacBook Pro M4 can support two. That limitation applies to built‑in discrete display outputs using the GPU pipeline. To drive *wo HDMI monitors in extended mode* you'll need one of two solutions:

1. A licensed Thunderbolt dock that uses native video output and multiplexer support (rare for non‑Pro Air due to hardware limit), or
2. A DisplayLink‑based adapter or dock, which uses software to emulate a second display output over USB and works around the single‑display limit.

Something like the following, should be considered:

• Plugable USB‑C Dual HDMI Docking Station (UD‑MSTH2)
• Plugable UD‑6950PDH DisplayLink Dock
