A:Answer Yes, you can connect your MacBook Air 15 to the Dell UltraSharp U4025QW 40" 5K2K monitor and use it as a large, ultra-wide display (essentially replacing two monitors with one). USB-C with DisplayPort Alt Mode: The monitor supports USB-C with up to 140W power delivery, so you can connect your MacBook Air directly with a single cable for video, data, and charging.
Thunderbolt 4 Dock (optional): If you want extra ports or multiple devices, you can use a dock.
