Windows 10: Microsoft 4K Wireless Adapter freezes when I open File Explorer

I have the Microsoft 4K Wireless Display Adapter, and whatever screen I'm running it on freezes when I open File Explorer. If I don't close File Explorer quickly enough, the wireless adapter disconnects. In case the specs help diagnose my problem, I am running Windows 11 on an ASUS A15 laptop with AMD Ryzen 7 4800H w/ Radeon Graphics and 32 GB RAM.

Microsoft 4K Wireless Adapter doesn't connect

Hi Lugoo,

thank you very much for your suggestions! After some more testing it turned out that it was my fault. If I press Windows + SHIFT + k. the wireless connection is established without a HDMI cable on the second HDMI input of my projector. I misread the instructions on the german connection screen of the 4K Wireless Adapter. I had only pressed Windows + k, without SHIFT.

Kind Regards

Microsoft 4K Wireless Adapter doesn't connect

I bought the Microsoft 4K Wireless Adapter (UTH00010) to replace the HDMI cable between my Windows 11 (22H2) PC and my Full HD projector Benq HT3050. The MS Wireless Adapter has the most recent firmware 3.9520.47. The PC has an Intel Wi-Fi 6E AX210 module installed.



I am able to get a wireless connection via the Microsoft 4K Wireless Adapter. However, this is only possible with a second connection between the PC and the projector via a HDMI cable on the projector's second HDMI input. If only the wireless adapter is connected to the projector, the screen "Press Windows + K to connect" is shown, but pressing these keys doesn't show any effect.



If i switch my projector to the HDMI input where the cable from the PC is connected, I can establish a wireless connection to the projector by pressing "Windows + K" and then activating the projector's other HDMI input with the wireless adapter.



Why does "Windows + K" only work with the cabled connection between PC and projector?
