Two Monitors on a MacBook Air M1 or M2: The Docks That Work
Apple’s specs for the M1 and M2 MacBook Air allow one external display. Plug two monitors into an ordinary hub and the second one mirrors or stays dark. That is a chip limit, and no regular dock can lift it.
DisplayLink docks get around it: a chip in the dock compresses the extra screens over USB, and a free app on your Mac draws them. Here are the two we would buy, and what you give up.

Setup: two steps people miss
Install the free DisplayLink Manager app on the Mac, then allow it under System Settings → Privacy & Security → Screen Recording. Without that permission the extra monitors stay blank. Anker and Plugable both state this requirement; it does not record or save your screen.
Apple Silicon Macs also ask you to allow new USB accessories since macOS Ventura. Approve the dock when prompted.
What you give up with DisplayLink
Protected video (HDCP) does not play on DisplayLink screens; Plugable notes that on macOS it may not play on any screen while the dock is connected. Expect slight latency, so DisplayLink is a poor fit for gaming and video editing. Plugable also says Retina (HiDPI) scaling is not available on its DisplayLink outputs.
For spreadsheets, code, documents and web work these limits rarely matter, and the extra screen space does.
On an M3, M4 or M5 Air? You may not need DisplayLink
M4 and M5 Airs support two external displays natively, and the M3 Air supports two with the lid closed. A Thunderbolt dock like the CalDigit TS4 is the better choice there.
Frequently asked questions
Do DisplayLink docks work on macOS Sequoia and Tahoe?
Synaptics, which makes DisplayLink, lists current macOS releases including Sonoma, Sequoia and Tahoe for its DisplayLink Manager app. Check its download page for the latest version before buying.
Can I watch Netflix on a DisplayLink monitor?
Usually not. HDCP-protected video is not supported on DisplayLink displays, so streaming apps may refuse to play there.
