Windows does not require reboot after Nvidia control panel changes, it appears. Trying to insert some snapshot, no sure whether it will work. My system is very new, was setup last week. Latest Windows 10, latest Nvidia driver (but no CUDA on Windows). So the option is just there in the NVIDIA Control Panel, if the images actually show up.
The two snapshots of CUDA-Z are captured before/after the DP option being selected and applied, without reboot. So you can see that they are 1:3 and 1:24 respectively.
Cheers
