If the monitor is connected to iGPU, you see the windows interface, which is rendered by iGPU. When you associate a dGPU with an application and launch it, you see the dGPU processing output data copied to iGPU buffer
You can associate Notepad launch on a dGPU, and running Notepad after that will give you eye-strain. But if you close (or minimize Notepad in windows taskbar), the eye-strain will disappear
I did that test with davinci resolve, and minimizing it to taskbar avoid eye-strain. It mean you cannot use rtx line cards without eye-strain at all, even with such dual-grapfic card tricks
