Lauda89 Hi there,

Just to clarify - you’re running the same software, same GPU, same cable and monitor and only a different processor & motherboard.

In my mind there’s only three things that could be up here:

  1. your HDMI is plugged into the motherboard HDMI and not the dGPU, meaning you’re using the Ryzen GPU. I’m guessing this is not the case but worth mentioning. To be sure, disable onboard graphics for your motherboard in the BIOS.
  2. Your GPU drivers have updated in the change. If it’s an Nvidia GPU, open control centre and make sure your resolution / bit depth / full or limited range colours settings are the same as previously.
  3. Don’t take this the wrong way, but I often experience a) a lag in my symptoms - they take days to ‘reset’ b) a negative version of the placebo effect when I change something and c) an exacerbation of symptoms due to stress. It could be worth trying to stay away from the machine for a few days and let your brain reset before trying again.

I know how frustrating this is!

But really it sounds like if you have the same crucial hardware and same software, there’s not really any way there can be a change in symptoms, which is actually a positive thing.

Fingers crossed for you.

      Yes all is the same, GPU driver and OS.

      Of course when I booted the PC, windows noticed that the MB and CPU are different so some driver updated it (like PCI).

      With the old PC I started having problems with 1909 and 2004, then 21H1 was fine.

      I honestly thought I could be safe by keeping the same GPU, monitor and software but apparently something is not working as it should.

      With the microscope and 240FPS recording I see no difference in pixels between the two PCs.

        Yes, different processor, motherboard, RAM (DDR5), PSU and case.

        1. 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....

        2. 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..

        3. 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 🙂

            Lauda89 windows told me that something related to the pci interface was updated and a restart was needed. So something happen..

            I would retry the cloning and use it offline and use an update blocker

              If it doesnt work, try Win 11 without activating it. Perhaps it is some driver problem.

              Lauda89 I know it's a old post but I have the same thing with it being a brain thing. What Windows version is good for you now ?

                  jordan I reinstalled 1809 and subsequently updated to 21H1.
                  But I no longer have that PC.. with my new PC (13700K + 4070)i have migrane with every version of windows, i think the problem is related to the MB BIOS. I have to use the PC with eyepatch.

                      Lauda89 oh interesting. It does seem Mb bios plays a role here. Going to try a few different motherboards myself.

                        jordan Right now, a lenovo legion 15 ICH laptop. CPU : i5 8300hq. iGPU : intel uhd 630. dGPU : nvidia gtx 1050.

                          On My Zephyrus G15 I can't find any os safe for eyes.
                          What's for you the best between:
                          21H2 LTSC
                          20H2
                          2004 ?

                          Thx a lot
