Screen sharing with miracast stopped working on my laptop

[v1184]

Miracast (wireless display) was working with no problem on my laptop until a few weeks ago. Now in every wireless display that I try to project I can't share my screen. I start the process, find the wireless device and press to connect with it. The system seems like is going to change displays but after a few seconds of loading icon every smart tv that I try reports something like "Connection was made but failed to share your screen, check your device for problems".

This started happening suddenly and I have no other problems in my wireless connections. I have tried to revert to previous driver of graphic card and wireless adapter but didn't work. I now have updated all drivers and bios to the last version and I still have the problem. Also updated the smart tvs, but surely the problem is not there because other windows 10 laptops can share their screen...

Processor is Intel celeron n2840

the integrated graphics card driver last version is 10.18.10.4358 (21/12/2015)

and the wireless adapter is Realtek RTL8723BE with last driver version 2024.0.4.108 (22/3/2019)

I tried the system restore with no success. Also the options I had were not so back in the past. I have this problem for almost a month now and the system restore was for 2 weeks before...

I constantly update the system through windows updates and hp support assistant. Yesterday only one update of .NET framework appeared. I installed it but no success as usual...

Thank you for posting back. 

I appreciate your efforts to try and resolve the issue. As you've performed all the relevant troubleshooting steps and the issue persist. 

I would suggest performing system factory default will isolate the failure, If its a hardware related issue then the computer needs to service. 

The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system. Click here: https://support.hp.com/in-en/document/c06162205 to Use the HP Cloud Recovery Tool (Windows 10, 7)

I 'd rather not mess with factory reset at this time.

Thank you very much for your help, but I will wait for an update that might fix the problem or just plug the cable to mirror my screen on the tv everytime.
