reaganry So tells us after a while how does it feel, if it really is eye strain free.

    So to make this work, do I only need to edit the registry file? or do I need to install the software mentioned?

      Seagull I think the software mentioned was used to generate the correct registry values to interact with the Nvidia driver.

      From what I can see just import the "ditherState - Disabled" line to your registry and it should work.

      Please can anyone testing this update this thread with results - very interested to know how it works out.

        In theory this ought to work unless dithering is enabled in hardware. We still don't know what is going on with VBIOS dithering/flicker.

        Aside from trying to monitor symptoms, is there any way to verify or validate that the changes took effect?

          MagnuM That's what I'm working on.

          Watch this space.

            Sometime next week I will try enabling dithering on my gtx 660 and see if I can make it uncomfortable. Its a strange first step, but I figure making a good card bad is easier as I can be certain a change has occurred if it starts causing me problems.

              Seagull I agree and also if anybody has a strain-free setup, upgrade to the latest OS and latest drivers - if there is more discomfort, even minimal - then yet again it's looking like this is a software issue.

                MagnuM I can see the lack of shimmering & feel the difference (immediate return of symptoms when i switch back to temporal d), but i dont get the expected color banding here[ http://i.playground.ru/i/26/98/02/00/blog/content/uhd4ha4c.jpg - should look like this https://i.imgur.com/o1zpgHn.jpg ], which i think means my BenqEW24 is now doing the dithering.

                    Did this actually fix any problems you had using that card for you? That is did your set up go from strain to no strain?

                      reaganry Sounds promising. What version of Windows are you running and are you on the latest Nvidia Driver?

                      Also would be interested to know if you get strain during BIOS-Startup or just in Windows?

                          diop win10 pro (1809) nvidia 750ti 417.35
                          strain=>nostrain and back again if i turn td back on.

                              reaganry And in the BIOS or while looking at standard VGA stuff (like booting from a Windows setup disk)?

                                  reaganry Are you using this machine for long periods? Hopefully it's not placebo or anything like that.

                                  I've got a GT710 in a W10 machine - I'll try the fix when I can to see if there's any difference even with a bad card - unfortunately to apply the fix will take at least 5-10 minutes and a few reboots (in which time my eyes get fried) so will have to give it time to thoroughly test out.

                                    I'm using the same driver (417.35) on a fresh W10 install to test.

                                    I initially had trouble importing the registry but just had to allow admin access to the key.

                                    First impressions; There may be a difference, but is more of a 50% improvement than 100%.

                                    I haven't used W10 for months but compared to my good W7 machine the colours are awful in W10 - over-saturated and the whites look harsh and blue-tinted compared to the 'creamy' W7 colour temperature.

                                    KM actually i think the bios does feel better too.. even though this fix shouldnt actually affect it ?

                                        reaganry If it changes the card hardware settings (doubtful but it's not IMPOSSIBLE) it could.

                                          Does the change have to be applied after each reboot?

                                            Anyone with a bad GTX 9xx/10xx and (not) Windows 10 try this and comment?
