1001 TVs로 macOS 설정을 사용하여 Mac 화면을 확장하는 방법

macOS allows you to extend your desktop to an external display using system display settings.

With the help of 1001 TVs, this capability can be expanded further—letting you extend your Mac screen to one physical display and multiple virtual displays for a more flexible multi-screen setup.

All connected displays show the same extended desktop and are fully controllable with your mouse, so it feels just like adding another usable screen while keeping your main display private.

1. Connect a physical display using macOS

On your Mac, go to Settings > Displays, click the + 아이콘, and add your physical display.

You can set either screen as the main display, and the other will automatically become the extended display.

Once completed, your Mac desktop will be successfully extended to a second screen.

2. Add multiple virtual displays with 1001 TVs

After extending your Mac to a physical display, you can use 1001 TVs to extend the same desktop to additional devices as virtual displays.

1) Connect to the same Wi-Fi network

Make sure your Mac and all target devices are connected to the same Wi-Fi network.
For best performance, a 5GHz Wi-Fi 네트워크 is recommended.

2) Install and open 1001 TVs

Install and launch 1001 TVs on your Mac and on any devices you want to use as virtual displays.

3) Start Extend Display mode

In 1001 TVs on your Mac, select Mac to TV, choose 확장 디스플레이, and then select your target devices (such as PC, Mac, phone, or TV).

You can click the + Add button to connect more devices as needed.

Only the Mac screen and the primary extended screen are interactive.
All other connected devices mirror the extended screen and display the same content.

This setup provides an extended desktop experience, allowing you to move windows between your Mac and the primary extended screen, while keeping your main screen content private.
