Yes, different processor, motherboard, RAM (DDR5), PSU and case.
No i am using the HDMI port of the dedicated GPU. Obvious that in the device manager I see two GPUs right now but the integrated one has "windows basic" as drivers. I might try disabling it (the integrated one) from the bios and see if it changes anything but I doubt it....
No, the GPU driver is the same (AMD 21.10.02) but windows told me that something related to the pci interface was updated and a restart was needed. So something happen..
I absolutely agree. These days I am still sick from the first attempt so I will have to rest a week and then make a second attempt.
If I don't find the solution with software I will have to try an nvidia GPU. I don't see it as a problem because by now my RX 480 is old and should be changed but there is the usual problem--I can't know if I will be able to use that GPU.
I will keep you updated.
Thanks for the help
