This guide explains how to control the “Optimize app window sizing on my PC” setting within the Phone Link feature on Windows 11.

What is Phone Link?

The Phone Link app is a tool built into Windows. It allows you to link your phone and PC using your Wi-Fi or Bluetooth. It lets you view your phone’s apps and data directly on your computer. You can chat, browse, or play games using your PC keyboard and mouse while your phone stays tucked away.

Once your phone is linked to your PC, you can manage how you see your notifications, choose to hear audio from the PC or phone, turn allow the phone link app to sync over mobile without Wi-Fi on or off, unlink your phone from Windows, enable or disable auto startup for the phone link app, send and receive text messages from the app, add or remove Phone Link on the widgets board, turn dark mode on or off, open your phone screen in the app, turn show notifications for all my apps on or off, show notifications in the Phone Link feature feed, enable or disable using Phone Link with Windows suggestions, open Phone Link notification banners in the mobile app or Phone Link, enable or disable Phone Link to show text messages, enable or disable Phone Link to make calls from your mobile device, and more.

Why use this feature?

When you use the Phone Link app and allow displaying your phone’s app on Windows, you can change the size of the app window on your desktop. This setting helps your phone apps look better on a large computer screen. When you turn it on, the window adjusts itself to fit your screen perfectly. If you turn it off, the window stays at its original size, which might be harder to read.

What happens when you are done?

Once you toggle this setting, your phone apps will either stretch to fit your screen automatically or stay at their default size. This gives you better control over how your mobile apps look on your desktop.

How to change your window sizing settings

Follow these steps to turn the feature on or off:

1. Open the Phone Link app.
2. If your phone is already connected, click the Settings button (the gear icon) in the top right corner. Note: This action may require admin privileges depending on your system account settings.
3. Select Features from the menu.

• On the Features page, look for the section labeled Apps on the right side.
• Find the tile that says “Optimize app window sizing on my PC.”
• Click the switch to On to enable it, or click it again to Off to disable it.

That is all you need to do!

Summary

The “Optimize app window sizing on my PC” setting makes mobile apps easier to view on your computer by resizing them to fit your screen. You can find this by opening the Phone Link app, going to Settings, and selecting Features. Enabling this makes your apps look better on a large monitor, while disabling it keeps them at their original size.
