## Product: Apple MacBook Air 2025 13-inch with M4 Chip
**Brand:** Apple

The [MacBook Air M4](https://shopsavvy.com/products/7826bbd3-ae81-dc1c-f6d9-b5d2eca2b909) supports two external monitors while keeping the laptop lid open. That's three screens total: two external displays plus the built-in Liquid Retina display.

This is a major upgrade. The M3 MacBook Air only supported dual monitors with the lid closed.

**Supported configurations via Thunderbolt 4:**

- Two displays at up to 6K/60Hz or 4K/144Hz
- One display at up to 8K/60Hz, 5K/120Hz, or 4K/240Hz

**Evolution of MacBook Air display support:**

| Model | External Displays | Lid Open? |
|-------|------------------|-----------|
| M1/M2 | 1 monitor | Yes |
| M3 | 2 monitors | No (clamshell only) |
| M4 | 2 monitors | Yes |

The M4 also improved resolution support. Both external monitors can run at 6K, whereas the M3 only allowed 6K on one monitor.

**Technical notes:**

- MST (daisy-chaining) is not supported. Each display needs a direct connection or a dock with separate outputs
- Both Thunderbolt 4 ports support display output
- No DisplayLink workarounds needed. Native hardware support means better performance and reliability

**Who benefits most:**

If your workflow involves multiple applications, spreadsheets, coding environments, or creative work, the triple-screen capability makes the M4 a meaningful upgrade. This feature alone convinces many M3 owners to consider switching.

For desk setups where you want maximum screen real estate without closing your laptop, the M4 finally delivers what MacBook Air users have requested for years.
