If the "enable the dual screen" feature doesn't work, launch your Shadow in "display safe mode" then quit your Shadow and relaunch it in normal mode. (The passage in display safe mode is used to clean your edid, which can be responsible for this error)

If you'd like to use a second screen or monitor with Shadow, we have great news: the Dual Screen feature is now included in the latest version of the official Shadow Launcher. To start using Dual Screen, follow the steps below.
Enable Dual Screen
The Dual Screen feature can be enabled from the Quick Menu on Windows, macOS, and Ubuntu devices.
For Windows, macOS, and Ubuntu
Step 1: Check the Quick Menu
While you're streaming Shadow, the Shadow Renderer will automatically detect if you have a second screen connected. To see if your second screen is detected:
- Open the Quick Menu. (Win+Alt+O or Cmd+Alt+O)
- Go to the Display tab.
- When the Shadow Renderer detects your second screen, the Enable Dual Screen button (2) will appear.
Step 2: Click the Enable Dual Screen button
Click the Enable Dual Screen button and your second screen will connect after a few seconds.
Step 3: Enable Dual-Screen automatically (optional)
If you want your second screen to automatically connect every time you start Shadow, click the Display tab, then check the box next to Enable Dual-Screen streaming automatically (3).
For Shadow Box V1
To enable Dual Screen on your Shadow Box V1:
- Using a display port, plug your second screen into the Shadow Box.
- Plug the display port in to your second screen.
- Start your Shadow from the launcher.
Shadow will automatically detect your second screen.
Configure your display settings
Option 1: Always match local resolution
If you'd like Shadow to automatically use your local resolution settings, open the Quick Menu → click the Display tab → enable Always match Shadow resolution with local Display (1).
If you want to choose your own resolution, disable this setting.
Option 2: Choose your own resolution
To choose your own resolution, click Display settings (2). A pop-up window will appear letting you choose your resolution settings.
Windows Display settings
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 limitations
Because this is a new feature, there are some limitations. You can find the most current limitations and known issues listed below. This list will be updated as we continue to make progress and changes.
List of limitations
While using Dual Screen, the bit rate used is divided by 2.
For example, if you set the bit rate to 50Mbps via the Launcher or the Quick Menu, the bitrate applied to each screen will be 25Mbps.
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.
We're currently developing new ways to address these issues, which will be available in 1 - 2 months.
