  • On Windows 7, eye strain is gone! And test the Ditherig.exe (wrong solution)

Glad to see you found a solution! On current Macbook Pro with AMD graphics temporal dithering/FRC is less apparent than my old ASUS monitor that had what appeared to be built in dithering/FRC "snow" according to manual.

About ACPI tables I had an idea on how I could use it for other laptops to override PWM frequency by direct communication to GPU registers (which store data) even on AMD/NVidia cards.

    JTL Your Macbook is great.
    I will try my best to make dithering disappear through ACPI. I don't know whether it will work, but I still want to work with Mac OS X, because on Windows keyboard and touchpad are not working correctly, that's annoying.

    And good luck to you too.

    Something's wrong with the picture links. When I try to open them, I get a "not found" error.
    However, I believe you took screenshots. On my iPad I see no difference between the (small) forum pictures. If you want to share what your display shows, you'd have to make real photos with a camera, not screenshots.

    I'm curious if you still have no eyestrain when you turn on Aero. That is the GPU-accelerated mode. At the moment you use Windows Classic mode.

      KM You're right, but my iPhone4s might capture bad image detail. But I will try in the next time, thanks 😛
      Imgur.com where I upload pictures is over capacity right now. I think it will be ok then after several hours.

      And I can't tell the difference between Aero mode and Classic mode, I think the colors are the same. The reason I like Classic mode is it's simple without many effects and animations, so I can switch windows quickly.

      I've used Mac OS X for a long time over 1 year, now I realize that Windows' color is pure, white is milky-white and green is green, they're not high-contrast like in Mac OS X, I can see red skin on people's face, but in Mac OS X, it's a little gray-like, just on the same Macbook. So is this OS related? I don't know. I'm still searching for information.

      What operating system do you use?

      Yes, I think Mac OS has a different "Gamma Point" (not sure how it's called).
      I used almost all current desktop OS except for Mac OS, to test them for eye strain issues. I noticed that with my ATI/AMD cards Windows Vista and 7 didn't have that especially strong eye strain when on Classic Mode. But any 3D-accelerated environment (even accelerated web browsers) reproducibly hurt within just a few seconds. That was why I asked for Aero, to get an idea if Intel Iris Pro has the same issues.

      I forgot to mention, I do not have any eye strain problems in Windows, too. I am currently using Windows 10 + NVIDIA. There is no classic mode anymore (only GPU-accelerated output), but with NVIDIA for me it makes no difference.

      so vinkenvvt you don't have any eyestrain out of the box with windows?

      I got the eyestrain also with intel iris pro and windows 7/8. But on an Acer notebook as I mentionend in my Intil Iris Pro thread.

      I have tried to use the ditherig application some time ago but the exe would not run. I think it's because I didn't follow the instructions in InPOut32.exe and treat it like installing a driver.

      I will try it on my laptop which was is Broadwell generation Intel graphics (HD 5500) on Windows 10. The author has not tested it on 5th gen Intel graphics or Windows 10 so I will report if I see any difference.

      vinkenvvt Maybe it's different because that variable name comes from the nVIdia disabling of dithering? And your on a Intel card, etc.

      I think this discussion that I posted might mislead people from the true reason of eye strain of computer Graphics.
