1 It is not possible to connect two screens locally on the Shadow Ghost due to hardware limitations.
2 Since the last update to iOS 16, it turns out that our additional screen feature is no longer functional. We are working to fix this issue in future updates.
Add a second local screen
If you'd like to stream Shadow to two screens from the same device, this is called a local screen setup. To use this setup, follow the steps below according to your operating system:
Windows, macOS, and Ubuntu
How to add an additional screen
- Plug your second screen into the device you'll use to stream Shadow. Make sure the screen has power and is turned on.
- Open the Quick Menu.
To open the Quick Menu, log into the Shadow launcher, then Start Shadow.
Once Shadow starts, click on the Shadow logo located at the top of the screen, or press the Quick Menu shortcut:Windows : ALT + WIN + O
macOS : ALT + CMD + O
Linux : ALT + SUPER + O
- Click the Video & Display section, then the Enable Dual Screen button.
(Optional) Other display settings
In the same Video & Display section, you will find other settings. Those are optional and not required, but they may enhance your dual-screen experience when applied:
Click to choose a custom resolution. Use the pop-up window to modify your resolution.
To make this setting appear, uncheck "Always match Shadow resolution with your local display".
|Enable dual-screen streaming automatically||
Check this box to have Shadow detect and use your second screen in the future.
|Always match Shadow resolution with your local display||Check this box to have Shadow use the resolution settings for your primary screen. Uncheck this box to choose a custom resolution.|
Note : If you decide to choose your own resolution, you'll have to manually change the resolution via a pop-up window every time Shadow detects a new screen..
What is the additional screen feature in Android?
With the "Additional screen only" or "Additional screen (extended)" feature, we allow you to use a computer screen directly on your compatible Android smartphones, using USB-C.
- Additional screen only: You can use a secondary screen as the main screen. The smartphone no longer broadcasts the Shadow.
- Additional screen (extended): You can use a secondary screen as a second screen. The smartphone still broadcasts your Shadow session. Here is the nexdock website that shows you the compatible Android smartphones list: https://nexdock.com/lapdock-for-smartphones/
Why “Under development”?
Because smartphone manufacturers use different components, APIs, and versions of Android, it is complicated for Shadow to adapt to all technologies and have a similar experience on all devices. This is much easier on iOS, as only the OS version changes.
However, we decided to release the additional screen feature since it is functional, provided it is activated as instructed in this article. We are aware that there are still improvements to be made and we will certainly improve the functionality per manufacturer little by little.
How to add an additional screen
When you log in to Shadow, the application automatically detects if you have a second screen.
When you open the Settings page, you can select either feature by clicking “Additional screen” then “Additional screen (extended)” or “Additional screen only”
Behaviors and tips according to your Android
|Device||Additional screen only||Additional screen (extended)||Additional info|

The cursor may disappear. The cursor will also disappear once you touch your smartphone’s screen.
This is a manufacturer limitation and we are currently working on a solution.

To close the application, please disable the additional screen from the settings, force the application to shut down from your main device or unplug your screen.
We advise you to launch Shadow from the smartphone to continue to have access to the overlay.
|OnePlus (presentation/mirroring mode)||
The cursor may disappear. When you touch the screen of your smartphone, the cursor will disappear. To recover the cursor, you must deactivate the option and then reactivate it.
|OnePlus (Desktop mode)||
To stop the additional screen, please close the application, force the application to shut down from your main device, or unplug your screen or you can disable the feature directly from the Settings.
The "Desktop" mode is currently under development by some manufacturers, which complicates the task. However, according to our tests on One Plus, it works better in "Desktop" mode. Here is a tutorial to activate it:
|Huawei (presentation/mirroring mode)||
The cursor may disappear. The cursor will also disappear once you touch your smartphone’s screen. To recover the cursor, you must deactivate the feature and then reactivate it.

How to add an additional screen
Shadow Box V1
- Connect the two DisplayPort cables to your Shadow Box.
- Connect them to your screens.
- Start Shadow from your Launcher.
Shadow will automatically detect your second screen. No additional configuration is required.
Change the layout of your screens
Windows will automatically decide the order and position of your screens. If you'd like to change the order or position, right-click the Windows desktop directly on Shadow, then choose Display settings.
A new window will appear. In this window, you can change the order of your screens and their positions.
Dual Screen Drawbacks
There are some existing drawbacks, and knowing these may help you troubleshoot any issues you might encounter. Open the list below for more information. This list will be updated as we continue to make progress and changes.
List of drawbacks
Shadow's Dual Screen feature relies on your local computer for decoding. The additional decoding needed to use Dual Screen may be stressful for your local computer, especially, if your computer does not meet our minimum requirements.
If you experience lagging or freezing, change your resolution to 1920 x 1080, then, gradually increase the resolution setting until you find a high resolution that doesn't lag or freeze. Scaling does not affect the experience.
Due to its popularity, the Dual Screen feature may not be as stable on the Ubuntu version compared to Windows and macOS.
Add a remote screen
If you'd like to stream Shadow to two screens from different devices, this is called a remote screen setup. To use this setup, follow the steps below:
Step 1: Start your main device
- On your main device, open the Shadow launcher.
- Log in to Shadow, then click Start.
Step 2: Start your second device
- On your second device, open the Shadow launcher.
- Log in to Shadow using the same email address and password you used for your main device.
- Click Start.
Step 3: Enable the remote screen
A pop-up window will appear after you click Start. The window will provide two options:
- Remote Screen
- Disconnect the other device
Click "Remote Screen" to stream Shadow on your two devices.
