I can finally reproduce issue on below setup where I initially observed that display freezes for a second or two and eventually freezing the external display completely.
Acer Nitro AN515-58 + Debian GNU/Linux 12 + kernel 6.1.0-17-amd64 + NVIDIA GeForce RTX 3060 Laptop GPU + Driver 545.29.02 + Display GBT AORUS F127Q-P with HDMI connection + Resolution 2560 x 1440 + Refresh rate as 60 Hz
This will help us now to debug issue much easier, apologize for delay in local reproduction.
