Kind time of day, there is a problem with the Miracast wireless display (WiDi) in Windows 10 when displaying on the TV screen. The device is found in the parameters, when the transmission is activated on the TV screen, a connection occurs, that is, the connection window on the TV pops up (only the computer screen function is selected), the TV screen turns off (becomes dark), the cursor (mouse) pops up on it and that's it ... Previously, everything worked, but after the update, it disappeared somewhere in December (Windows 10). I checked it as you recommended, did the DxDiag test (Miracast: Available, with HDCP). Maybe this is the problem (Miracast: Not Supported by Graphics driver)?
Best regards, Mikhail.

Hello. The error "Miracast: Not Supported by Graphics driver", like "Miracast: Available, with HDCP", which appears when checking DxDiag, indicates problems with image transmission via Miracast from the graphics adapter, or rather the driver. In your case, if everything worked before, then at the hardware level both the video card and the Wi-Fi adapter support Miracast. There is no specific information on these errors on the Internet. Even on the official Microsoft Community forum and English-language sites, experts recommend contacting the support of the manufacturer of a TV, laptop, etc.
All that can be advised in this situation is to experiment with the video card driver. You have not written, you have a PC, or a laptop ... Download the driver specifically for your laptop model, or video card from the manufacturer's website and run the installation. After installation, restart your computer and try to display the image on the TV.
If it does not help, try rolling back the driver (if you have this function active).
You can also try to replace the video adapter driver from the list of installed ones.
- In the device manager, right-click on the video adapter with the right mouse button and select "Update Driver".
- From the bottom, select "Search for drivers on this computer".
- Select a driver from the list of available drivers on your computer.
- We select one of the drivers from the list (there may be several of them) and install it.
Also install a set of codecs. For example, K-Lite Codec Pack Full.
Do you have two video cards in the device manager (have integrated graphics)? If so, follow these steps with two video adapters.
Have you tried changing the mode of displaying the picture through the wireless display function through the Win + P menu? Are you doing everything the same way as before?
The only way. Once everything worked before, and Mirakast stopped working after updating Windows 10, then something is wrong with the software. I don't see any other options.
