Cuda not on primary Device (screen)

C++
,
1

Hello everyone, I have been working for several years now with OPENCV and CUDA. (currently versions 4.8.0 and 12.2 respectively). Everything works fine in my different jobs but I’ve always been stuck on an element that I can’t find (I’m on Windows 11).

I have several monitors connected to the GPU which allows me to display my work. And I also have a monitor connected to the CPU.

GPU : NVIDIA GeForce RTX 3060 Ti
CPU : Intel(R) UHD Graphics 630

If I set through Windows that the monitor connected to the GPU has priority, everything works fine.
Whereas if I define my monitor connected to the CPU as a priority (under windows), I can no longer use my program.

I already tried to use “cv::cuda::setDevice” but without success.

Here is my configuration as needed.

thank you for your advice.
