5 Things to Know About Dual Monitors on a MacBook Air

DisplayLink adapters enable two external monitors Even M1/M2/M3 MacBook Airs, which natively support only one external display, can run two via a DisplayLink adapter.

Performance depends on your workload DisplayLink compresses video over USB and decompresses it using the CPU. Static tasks like spreadsheets and code work fine, but video playback, scrolling, and gaming cause stutter and lag.

You lose a USB-C port The adapter occupies one of your limited USB-C ports, reducing connectivity for other peripherals.

Driver updates can break things DisplayLink drivers sometimes stop working after macOS updates, requiring a reinstall. This is not a reliable long-term solution.

One external monitor plus the built-in screen is better If you can manage with one external monitor and the laptop’s display, skip DisplayLink. It’s smoother and less hassle. Only use it if you absolutely need two external screens and can tolerate occasional glitches.
