Assign processes to different GPUs (Windows 10)?

I have 2 monitors in my company. One via PCIe and the other via onboard. When I open the Task Manager I see that most of the applications are taken over by the PCIe GPU. The idea is to run games on monitor 1 via the PCIe and, for example, to run Twitch or Youtube via the onboard GPU on monitor 2 so that I have more power when gaming.

Although the programs are shown on monitor 2 it says that my PCIe card takes care of it! Can you assign individual GPUs to processes in Windows 10?

Either… Or. You can't get a dedicated graphics card and the igpu in parallel. The integrated is deactivated when a pcie card is recognized

I turned them on in the bios with the multi-monitoring function. The second monitor is also connected to the HDMI. Or do you mean that she just passes the signal on?

Oh this Intel Multi Display e.g. Yes, that is only because the house does not have the appropriate or too few connections for the graphics card. Or you have a graphics card that no longer downclocked with 2 monitors. Is only a tool to connect multiple monitors. Distribution of tasks and co. Can't you do that? This option is only useful to display the picture. The GPU continues to do the work. Not the integrated graphics unit. Do you have a strong GPU. Then I would only ever connect the monitors to the GPU and deactivate the igpu
