After a year of back/forth trying to find out why I am getting dizzy when using my computer (beyond a nasty B12 deficiency that has made it harder for my brain to interpret signals like dithered colors)…. I was able to reduce the strain in a few clicks by ensuring my Nvidia card sets the colors vs. Windows. This instantly removed some of the “weird” colors (like black was actually a brighter gray than black).

Here is the guide I used, I hope it helps someone else: https://www.ihse.com/wp-content/uploads/files/whitepapers/ihse-tech-brief-disabling-temporal-dithering.pdf

    Can you quantify the difference this made? E.g. strain to no strain at all? Headache within 5 minutes to headache after 45 minutes, etc.

        I'm not sure I understand what setting you changed.

        Did you go into the nvidia drivers: change resolution and flag "user nvidia color settings?

          Lauda89 Yes. Per the guide, I used the Nvidia Control Panel to see the colors. This made black look like black versus a faded/dithered gray/black, as an example. The link I posted is what I followed.

            Thanks for the tip.

            Dizzy beyond a nasty B12 deficiency that has made it harder for my brain to interpret signals like dithered colors

            Was the deficiency assessed via a test (blood?) or is it a speculation?

                This supports my own research done with capture cards, some colour settings on NVidia cards do not dither. In the few cards I tested, there was generally one colour setting which did not dither, and the rest did. Unfortunately, this setting was different for each card I tested. What I believe is occurring, is that there is a native colour setting for each card, and dithering is used to translate the output to others.

                  AGI extensive bloodwork over years and genetic testing to determine what is blocking methylation/impairing supporting processes.

                  • AGI likes this.

                    Seagull that sounds about right. Thank you for your research.

                      @Dizzy Are you using HDMI or DisplayPort? Perhaps the thing that changes was the Color Range from Full to Limited.

                      was it confirmed that dithering is off when setting settings like PDF document shows? There are no specific driver versions mentioned and I know that is very important as older version GPU with old driver versions do not dither. So the question is it possible the document is very much fake.
