[Windows] Mirror or Extend Your PC Screen to Your Phone, Tablet, TV, or Other Computer

In today’s multi-device workflow, a single screen is often not enough.

With 1001 TVs, you can easily extend your Windows PC display to your phone, tablet, TV, or another computer—creating extra screen space for work, multitasking, and entertainment.

In addition to extending your screen, 1001 TVs also lets you mirror your entire PC screen or share a single window, depending on your needs.

Why Use Screen Extension?

· Boost Your Productivity: Extra screen space lets you keep reference materials, chats, or tools visible while working on your main screen—reducing constant window switching.

· Create Your Ideal Setup: Arrange windows across screens to match your workflow, whether you’re coding, designing, presenting, or multitasking.

6. Done!

Other Screen Casting Modes in 1001 TVs

Mirror Whole Screen (Duplicate)

Mirror your entire PC display to another device. This mode is ideal for presentations, demos, or watching videos on a larger screen, where both screens show the same content.

Share a Single Window (Select window)

Mirror only a specific window from your PC instead of the full screen. This is useful when you want to focus on one task while keeping the rest of your desktop private.
When using Select Window mode, choose the app window you want to share.

You can switch between Duplicate, Extend and Select Window modes from the screen selection menu in 1001 TVs.
