Remove horizontal black bars
If you're seeing horizontal black bars on your screen and your CloudDeck's stream is not filling the whole screen, you can try the following:
- Open the Moonlight settings and change the resolution to Custom.
- Enter the native resolution of your client device's screen or a resolution with a similar aspect ratio. Recommended values are 1680x1050 for most MacBooks and 1280x800 for the SteamDeck.
- Click OK and connect to your CloudDeck.
- Press Esc to open the Steam menu.
- Navigate to Settings → Display.
- Uncheck Automatically Set Resolution.
- In the dropdown that appears, select the same resolution that you have set in Moonlight.
