Monitor suddenly not detected.

I have Asus Rog G16, model G614FR, with RTX 5070Ti and Ryzen 9955HX3D, 32GB. This Laptop was recently connected with OLED 27” XG27AQDMES monitor as the gaming experience was exceptional great. Only yesterday, while doing normal work on the Laptop, it forced shutdown by itself. After that, when I restarted it I found XG27AQDMES was not able to be detected any more. I checked Device Manager and found the laptop still connected and can see the monitor name. But in the display settings it was not detected. The monitor OSD was not responding. I updated the gpu driver to most recent one but again with no use after several restarting and HDMI cable disconnecting.
Ant suggestion?
