It seems OK for me. I was still starting my TV 10s after the PC and I didn't want to install any updates. I finally did it because there was nvidia-graphics-drivers-515 - 515.76+really.515.65.01-0ubuntu1 which was a fix for https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-515/+bug/1993041. This issue seems specific to RTX30xx cards plugged on HDMI, this is my case. I rebooted, it works even if I didn't shut my TV off.
