commonly used access point. Some channel switching is unavoidable if there are
multiple Wi-Fi networks or access points in the environment. In this scenario, ensure all
Wi-Fi drivers are up to date.
In compliance with regional governmental regulations, all 5-GHz wireless devices in
Europe, Japan, and Israel don't support the Unlicensed National Information
Infrastructure-3 (U-NII-3) band. In Surface Hub, the channels associated with U-NII-3 are
149 through 165. This includes Miracast connections on these channels. Therefore,
Surface Hubs used in Europe, Japan, and Israel can't use channels 149-165 for Miracast
connections.
Device resolution not supported error
Connect app exits unexpectedly
When you try to project from a Surface Pro, Surface Book, or Surface Laptop to an 84-
inch Surface Hub by using the HDMI port on the Surface Hub, the error message
"Device Resolution isn't supported" is displayed.
Cause: The Surface device isn't set to a supported 84" ingest resolution. By default,
Windows tries to connect to the Surface Hub using Duplicate mode, duplicating
your desktop on both screens. But the default resolution of the Surface device is
higher than the 1080-p resolution of the Surface Hub, so the Hub can't display the
higher-resolution image.
Resolution: Projecting to a second screen can be accomplished by using Extend .
Extend is used to expand the desktop user interface across your Surface and
Surface Hub displays, allowing each to display the desktop in its native resolution.
Use one of the following methods to configure your Surface to display your
desktop in Extend mode.
Method 1: Change the desktop resolution
1. Open Start , and then select Settings > System > Display .
2. Select the Surface Hub display from the choice made available.
3. Under
Scale and layout , change the setting under Resolution to 1920 x 1080 .
