Secondary screen flashes black

After upgrading from Fedora 43 to 44, I have problems with the second monitor going black and coming back again and again at varying intervals. I am using a Lenovo Yoga with 16GB RAM and the external monitor is a 64 inch flat screen TV. I have experienced this before when there have been major updates to Fedora, but after a few days of updates this problem has gone away, but this time the problem has not been fixed yet.
