Issue with Windows Wireless Display Adapter

[Oaktech]

I've been asked to get a Windows display adapter working in one of our meeting rooms and it's not playing the game.

 

The environment is Unifi wifi, NEC Screen, Variety of laptops (4th, 6th, 8th &11th gen i series with integrated graphics with up to date drivers) Windows display adapter on firmware 2.0.8350, Windows version: 10 21H2, 22H2 and Windows 11 22h2. Same behaviour on all devices.

 

Turning on the screen and selecting the input shows the Microsoft loading screen, then the advice screen from the display adapter.

 

Win + K on the laptop opens the side panel, shows the adapter.

 

Clicking on the adapter shows the device trying to connect, the top bar drops down on the laptop and the image on the NEC screen goes black immediately and then shows the Microsoft logo for a couple of seconds, then goes black and the wireless display adapter reboots and come back up to the advice screen. Laptop says unable to connect.

 

This is the first one of these we've bought.

 

Any ideas?

Never mind - the NEC only puts out 500ma not the required 1a. An external power supply fixed it.
