Hello the members of the forum,
Could you help me to solve the issue ?
[Details of the Issue]
A monitor connected by a displayport shows vertically same two displays with NVIDIA driver (ver. 460.27.04).
If I connect the monitor by HDMI, the monitor normally works (shows a single display on the monitor).
I noticed the issue after updating the NVIDIA driver of my PC.
Before updating the NVIDIA driver (ver. 460.27.04), I used the NVIDIA driver (ver. 430.33.01) and the monitor normally worked if I connect the monitor by displayport.
Thus, I guess that the new NVIDIA driver raises the issue.
Of course, I can normally use the monitor connected by HDMI.
However I would like to use dual monitors.
