Allekss Not sure about that.

Modern graphics are 8-bit by default, and the idea is actually getting a 10-bit signal to a monitor is Work, so by virtue of not doing anything you're usually in the clear 😃

    Allekss i have the 6 bit option on my 580, but it doesnt seem to help much

      ditherig author does not answer to emails, the program clearly does not work in my computer. I shows temporal flicker videos about it. I wrote ditherig author 2 times and no reply. I thought he will fix his software.

      Has anyone got a reply from him? His email is s_kawamoto2307 at yahoo.co.jp

        The only solution for any dithering problems is get CRT screen that can't dither no matter what the software or video card does.

          smilem GPU dithering is possible on every monitor including 10bit monitors?!

            smilem Makes no difference if the signal is converted from digital->analog with dithering intact.

              "Makes no difference if the signal is converted from digital->analog with dithering intact."

              You can't cheat laws of physics, phosphor on CRT disables all kinds of dithering the software or GPU hardware related. It's like water can't burn. So same here CRT can't dither.

              @si_edgey I have an interesting observation. When i look to your background picture with windows photo viewer its ok - i see horizontal bandings - dithering is turned off. But when I look at it through google chrome - I do not see any bandings. I do not know what is it and how we can explain it

              JTL Moire patterns, from wiki : "Photographs of a TV screen taken with a digital camera often exhibit moiré patterns.

              To avoid the effect, the digital camera can be aimed at an angle of 30 degrees to the TV screen."

              Maybe this should be a part of our testing method ?

                  I think using standard framerate cameras is "barking up the wrong tree" for testing for temporal dithering or other onscreen artifacts (i.e not backlight PWM).

                  Don't have the link handy but I believe the Blur busters person (from another forum) says in order to catch "everything" you need a camera with a framerate of at least ~5000fps. Not cheap.

                  You might be thinking "Well, why do I need that for capturing from a 60Hz display?". I assume when you get into issues such as LCD inversion, FRC (monitor sided dithering) and such that aren't necessarily tied with the monitor "refresh" frequency, that's when you need to bring out the fancy stuff.

                      MPaz This is true, through HDMI, the eyes hurt more. Especially painful (for the eyes) at a frequency of 120/165/240Hz. Through DisplayPort, the problem goes away. The "pseudo" 10bit (8bit + FRC) panel means that no FRC (pixel flicker) image is used to output 8bit. If, of course, you do not have 10bit mode selected? To disable Temporal dithering on Nvidia graphics cards

                      To reduce the "response time," a black frame insert (backlight blinking). ULMB, ELMB, VRB, etc. (turn off).

                          JTL The flicker (backlight) of the monitor can be seen even through the "pencil test."

                          This is especially noticeable on phones with OLED/Amoled screens. If the backlight flickers, it can be seen as "stripes" on the screen, on the phone's camera.

                          There is also pain in the eyes from the pulsation of the LED lamp (above your head). The "pencil test" works here, too. A more visual way, through the camera phone. I set 720p/240fps and change the shutter speed.

                          Answering questions, - Does my monitor have flickering? You need to go to the displayspecifications site and enter the model of your monitor. For example, Acer EK240YAbi (recently sold). We look at "Panel bit depth" = 8bit (6bit + FRC). Your eyes will hurt (due to FRC/pixel flickering). Although the backlight is (at the same time declared as) Flicker Free.

                          My eyes hurt from Intel iGPU too (even on the 8bit | Flicker Free monitor). I change the video card to Nvidia/AMD and the pain goes away. The same with HDMI cables (eyes hurt a lot). I change the cable to DisplayPort and the pains go away. On the monitor, Xiaomi X27G had to turn off "response time" (backlight blinking/black frame insert) from fast to normal.

                          The main thing is that you have a Flicker Free laptop screen. - Where to see? You need to go to the notebookcheck.com website and enter a laptop model. For example, the new MacBook Pro 14 2023 M3 Max (2023) has PWM = 15,000 (for $3200 it’s kind of cheap). When the same Apple-MacBook-Pro-13 (2020) has PWM = 113600 (7.5 times better). The higher the PWM, the less tired the eyes are.

                          Things are much worse with cheap laptops. Lenovo-IdeaPad-330-15ARR (2018) has PWM = 200 (200 in total, Karl!). Dell-Inspiron-15-3585 (2019) has PWM = 250. On older laptops (at <100% brightness), PWM was rarely >2000. Flicker Free laptops MSI Stealth 16 Studio (2023) or Lenovo Legion Pro 5 16 G8 (2023). The human eye does not see PWM above 25000. In any case, the decision "which laptop to buy?" depends on you.

                              jordan In your place, I would buy three (monitor $110 costs). (1) Enabled FreeSync Premium through the monitor menu. (2) Changed Response Time from Fast to Normal. (3) Twisted brightness, gamma, contrast. Tested on Intel HD 610

                                AlanSmith I'm curious where that displayspecifications site is getting their information from. They list my monitor (LG 24GQ50F) as true 8 bit, but I can see what appears to be dithering.

                                I don't think it's coming from the source device since I'm using a Intel iGPU, which don't dither, or so I've read on here.

                                    silentJET85 there is no Intel iGPU that does not dither, specially the newer ones.

                                    so many people have problems whit integrated graphics chips especially Intel. try a dedicated nvidia gpu whit your screen and set it up from Nvidia CP to run on Nvidia colors 8BIT FULL RGB and you should have real 0 dither then whit a true 8bit screen

                                      silentJET85 The LG 24GQ50F does not use PWM (Pulse Width Modulation) to regulate backlight brightness at any level. Instead, DC (Direct Current) is used to moderate brightness. The backlight is therefore considered ‘flicker-free’, which will come as welcome news to those sensitive to flickering or worried about side-effects from PWM usage. The exception to this is with ‘1ms Motion Blur Reduction’ active, a strobe backlight setting which causes the backlight to flicker in sync with the refresh rate of the display. Read the overview on the monitor. (1) You can disable "flickering". Select [Menu] → [Game Control] → [1ms Motion Blur Reduction] and press [OFF]. (2) Due to "Response time," the eyes can also get tired. Better to turn it off. (3) Then turn on Freesync Premium. What is strobe backlight? Read from here.
