windows 11 miracast black screen

Often, when you are wirelessly screen sharing using Miracast on Windows 11, the display turns black. Switching to a wired connection may fix the problem, but that brings in cables, something that Miracast, a wireless screen mirroring protocol, claims to get rid of!

Miracast, also commonly known as HDMI over Wi-Fi, shows a black screen due to using an incorrect projection mode, misconfigured network settings, corrupt or outdated graphics driver, or conflicts created by other software.

Before you start troubleshooting, make sure both the PC and the other display are connected to the same Wi-Fi network, and that both devices support the Miracast standard. Also, remember that the Windows 11 N edition doesn’t support wireless screen mirroring.

How do I fix a Windows 11 Miracast black screen?

1. Change the projection mode

  1. While connected to the other display using the Miracast wireless protocol, press Windows + P to view the projection modes.
  2. Now, if it’s set to PC screen only, switch to Duplicate. This will project the computer’s screen to the TV or another display.duplicate projection mode to fix windows 11 miracast black screen

Updating the graphics driver often helps fix issues triggering black screen with Miracast on Windows 11. Also, while you are at it, update the network adapter drivers.

If you have been seeing a black screen with Miracast in Windows 11 or 10 ever since the start, it could have to do with the installed antivirus. A few found ESET Internet Security to be responsible for the issue!

I recommend you first disable the third-party antivirus, and if that works, uninstall the program and then switch to an effective antivirus solution.

7. Use third-party screen mirroring software

If nothing else works, you can always use a top-rated screen mirroring software. The best ones will help get rid of the black screen and allow you to connect wirelessly to a display using Miracast on Windows 11.
