screen mirroring

HP Recommended
hp laptop, bought in 2017, 16gb Ram

I was able to screen mirror my laptop with my Sony TV, but now it connects and something appears and disconnect. I can not even read the notification, it just goes away too quick. why I can not screen mirror where I did it before.
