I signed the change.org petition and will be posting it to other forums. u/BloodyHell619 have you found a solution to this problem? . They checked how it's done and said Nouveau's temporal dithering option is always disabled, except for laptop type displays. It seems that NVIDIA has implemented some sort of temporal Dithering in all its RTX cards, and it's causing me severe eye strain and pain. Temporal Dithering eyestrain / fatigue Hi all, The purpose of this post is to raise awareness, help each other, and unify our voice regarding the (alleged) adverse health effects of temporal dithering. To take advantage of temporal dithering: Code your animations as if they were going to run at normal full brightness; use the full range of 0255 for RGB and HSV values as much as you wish. It could be that in the old days the drivers did the dithering and it could be disabled and enabled from the software but now drivers just send the image to the hardware and the hardware does the dithering which means it can't be turned off because it's "baked into hardware". It also does nothing in reducing the pain. Maybe for some of you this is more clear when you read it than it is to me? Font anti-aliasing is a major issue for eye comfort, but there are other major and possibly minor issues. Home of the computer component that you see most, your Monitor. I appear not to notice anything on my Macbook Pro display, although that could be caused by, a) Me not knowing what to look for If there's one thing I've learned on this forum is that our problem is largely unknown. . I did my research and a few people blamed temporal dithering of being the culprit. I mean the kinds used at concerts. Here is the above mentioned email to the amd-gfx list. Basically all my monitors dither. From what I understand Temporal Dithering seems to be the issue. It could also be that only FRC (display hardware's own, internal dithering) appears as 15 Hz flicker while external temporal dithering (graphics hardware, graphics driver) would be sent inside the normal 60 Hz video signal, thus . Hey folks,I have an XPS 13. Some time ago I talked to the devs in Nouveau's IRC channel. I encourage people to dismiss anyone who provides any non-constructive feedback like go see a doctor, or adjust the resolution or brightness. Eye strain is caused by temporal dithering (GPU issue) or PWM (monitor issue) or something else. It would explain why I was able to use OLED Android phones for years. I upgraded the hard drive and had to install Windows 10. Temporal dithering is a technique used in displays to emulate more colors than the display can actually show. a 10 bit graphics card with an 8 bit display panel). Will a true 24bits display outperform a 18bits one in (2D) picture quality or is this difference neglectable? It could also be that only FRC (display hardware's own, internal dithering) appears as 15 Hz flicker while external temporal dithering (graphics hardware, graphics driver) would be sent inside the normal 60 Hz video signal, thus becoming 30 Hz flicker(?). I am afraid that depends on the dithering algorithm used by the manufacturer. Laptop: Dell XPS 9560, with 1080p FHD matte screen Physical therapy. It's main benefit is in regard to angles and lack of IPS glow, due to the A-TW polarizer (in 1st gen models). Disabling dithering enabled by default can be done to get the best quality for 8 bits or higher displays or to mitigate eye strain. Of course, on top of that, the monitor could then be doing its own dithering. The NEC 2490 is okay as far as eye strain goes, at least to me. NVIDIA GPUs automatically does that (GPU level temporal dithering) when the DVI or DisplayPort cable is put into 6bit mode, especially during the 220Hz overclocking of a BenQ XL2720Z. Hey folks,Hoping the Dell team might be able to answer this. (Or is this a question that depends on which vendors display panel gets put in the laptop? I hear temporal dithering or the flashing of 2 colors can create a flicker that is bad for health. Google. I came across this thread on the subject: It seems that dithering is enabled by default in Intel graphics drivers, and that there is no way for a user to disable / toggle it. I think temporal dithering is actually a bigger problem for my brain than pwm. Dispersed dot ordered dither l c The term ordered dither refers to . He says it appears as a spike at 15 Hz. TEMPORAL DITHERING Dithering is a technique to compensate for missing color values to increase the perceived amount of color and shading. IIRC for such displays color depth checks are done to see if temporal dithering is needed to create the illusion of 8-bit colors. Inflammation of your eyes; Eye inflammation may cause blurry vision and migraine. You'll most commonly find temporal dithering in hardware, specifically to improve the appearance of an image on a sub-par television or monitor display. I discovered that the video card the hypervisor is showing to the guest virtual machine is usually pretty basic with 8-bit color depth. Press question mark to learn the rest of the keyboard shortcuts. Samsung, LG, AUO, ). What happens is exactly what @Eigenvektor described, if your monitor has an 8bpc panel and supports 10bpc by FRC, then you can chose in your display settings, if you want to use 8bpc or 10bpc output. I have a feeling understanding all this is vital to understand possible eye strain effects of temporal dithering. I have an XPS 13 that had temporal dithering disabled from the factory. They all show a basic video card to the guest OS. In linux kernel gpu source code: Line 188. Try hard-refreshing this page to fix the error. I didn't stretch out the 240fps video to 60fps before upload so youtube cut down the frames but playing back the video at .25 speed shows the dithering. That version gave me really bad eye strain. It is very scary. Apr 2, 2004 119 11. Or even better:- Does anyone in Dell support know how to disable Temporal Dithering with an Nvidia GPU? I've made an example of dithering using frame rate control but I preface it with the warning that it may be unsafe for those with epilepsy. Turns out all Macs from 2016 onwards are giving me eyestrain. 10 minutes and my eyes hurt and I need to stop. Ask Apple to offer an accessibility option to disable temporal dithering. If those GPUs actually have undefeatable dithering built into their output, that would be a terrible design flaw. Treatment of temporal tendonitis can involve multiple processes such as: Anti-inflammatories like ibuprofen. Ask Apple to offer an accessibility option to disable temporal dithering. When I was talking to the head of displays for Apple, he mentioned the fact that laptop displays have more pins compared to let's say HDMI or VGA because they are just "dumb" panels that can't do much on their own, relies on external driver/controller board to handle brightness/PWM/connect to GPU, etc. I pinpointed my issue with my MBP 16" 2019 with Intel CPU to the temporal dithering by working with a virtual machine. Other symptoms of eye inflammation may include as follows: . It does seem logical because it's changing many pixels in many different ways and so if your eyes can pick it up then it should definitely be painful. Instead in the place of pixels there are these mini nodes that flicker back and forth rapidly (dither), presumably filling the space with an even richer viewing experience. but when I record the screen with a screen recorder on my pc like OBS no change is happening in the recorded video. Too bright of a display and/or a flickering display can fatigue the eyes really fast. It is a good laptop, I really like it. Thanks, and please share any experiences, solutions, or leads. At least with the Intel Iris graphics. I already have a 2015 MBP of my own, you just need one physical OS X machine that has the GPU for development, the other machine for debugging can be a VM. So temporal dithering or Frame Rate Control(FRC) is a technique where pixels are flashed between 2 different colors to simulate a 3rd color correct? This spatiotemporal dithering method takes advantage of both spatial and temporal dithering, bringing in an extension on the color depth and an improvement on the display quality without flicker problems. Apple support advised me to leave feedback. If I use a true 8bit display would that mitigate any dithering? In posts #22 and #25 he talks about dithering and says that by analyzing the frequency spectrum one could see if (monitor panel's) temporal dithering is active. Samsungs 172x is an 18 bit panel yet uses an excellent dithering algorithm making it better then some full 24 bit panels. Again, I am someone who sits in front of screens endlessly. Temporal arteritis causes the arteries, particularly those at the temples to become swollen and inflamed. Can someone confirm if xbox one and ps4 do in fact have temporal dithering enabled and if so is there a way to turn it off. You can use novideo_srgb to control the dithering. I hear temporal dithering can cause eyestrain and headaches. Also, please share with us: 1- your experience and symptoms. Of course it's more a workaround than a solid solution to our problem but I thought I'd let you know, in case it benefits you. omissions and conduct of any third parties in connection with or related to your use of the site. This site is best viewed in a modern browser with JavaScript enabled. Yes, they did this when display is 6 bit (or 18 bit), that causes eyestrain. If it is left untreated, it can cause . But with MBA 2022 it does not seem to work but instead full brightness lowers the eyestrain on this model for me, whereas with MBP 2019 the brightness did not affect but lowering the color depth with SwitchResX did. Another thing which changes with refresh rate is rate of temporal dithering (either done by panel/monitor or GPU) but this should not cause eye-strain. Question for the Dell Support folks: It seems the folks at Dell have figured out a way to disable temporal dithering. Many of the source authors are Google employees. . Here are a few of the posts about people complaining about the same issue even up to the 3090 and down to the 2000 line up. I have been reading on other forums. This disabled temporal dithering for Intel graphics cards. What might have caused this ? Temporal Dithering is when a graphics card has more colors than a display panel can support (eg. , For example I believe many desktop TN panels implement dithering in hardware, such as my old ASUS monitor that I ran at high brightness to mitigate PWM, it gave me no other problems in the two years of using it before it's failure, although I sometimes could see a slight snow effect on certain backgrounds which doesn't seem to manifest on my Macbook (maybe because have higher resolution/better implementation on Samsung panel/different GPU setup?). Would using an 8 or 10 bit monitor make any difference? Muscle relaxants. (dithering) I was going to look into it. Make sure that you're not using FRC on your monitor (e.g. FRC # One of the major causes of eyestrain. These suggestions did not solve the problem, although changing the scaling made me a bit more comfortable to use the screen - but still it is not optimal and the strain/fatigue effects are still there. We can confirm on LinkedIn if the employee is still at Google (or just email anyway and hope they are). I have a Late 2019 MBP 16" and I am experiencing very similar symptoms and issues. I have read mention of modifying the settings in OpenGL which I do not know how to do or initiate. I got terrible eye strain and headaches from using the computer for a few hours. 5- do you have any resources for this (is it really temporal dithering? Today we have a look at some different techniques to add depth to our materials - WPO, Displacement and POM. https://gist.github.com/jtl999/9e30067b1fd3e5bf37366e55a5248803. Although, all the people with this issue seem to have had an untrue 8bit monitor (6bit+FRC). From reading online the culprit seems to be temporal dithering. u/dogelition_man I have tried the novideo_srgb and a few other apps like it. It seems this dithering thing has started to get implemented since the start of the RTX lineup. This works to frame the page in the Window. Display color temperature is another major issue. I don't know for sure but it seems to me that modern video cards don't seem to care how many colors the panel supports. 2- your computer model. I have another question for the Dell folks. This is referred to as temporal dithering. You'd need to use a capture card/digital video analyzer to really know what the GPU is sending to the monitor. No other device has ever caused me .

When . With the new screens that promise 'billions of colors' they don't actually offer a complete screen full of rich static pixels. In the beginning this was really bad for me. Is it possible that the FRC/temporal dithering used on 6 bit monitors to achieve an 8 bit color representation is the issue? intensities that are integrated over time by a sensor (eye or camera) to produce the desired brightness value. For example AUO 18 bit TFT Panels have an unpleasant "flashing" effect due to a poor dithering algorithm. After all some 24 bit panels reproduce color so poorly that an 18 bit panel with good dithering will produce far better color. https://community.intel.com/t5/Graphics/eye-strain/m-p/535914. Less, User profile for user: Does it use Intel Graphics, or NVidia or AMD video? Is anyone else suffering from the same experience and knows of a way to fully prevent this dithering? Apple support advised me to leave feedback. I probably would part ways with Apple going forward for this. Panels that are 6bit+frc or 8bit+frc utilize this technique correct? Something went wrong while trying to load the full version of this site. I only started having problems when I recently got the new 13" 2020 MacBook Pro (Intel Iris Plus Graphics). By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. I am a longtime user of screens, primarily Apple products. The other reason could be that the more bits for color are transferred the more bandwith it requires but bandwidth has an upper limit and since the brain mixes colors together anyway if you flip them to the eye fast enough, it's more efficient to alternate between two colors than to send the additional bits. Moreover, the dithering of the pixels may be selected to follow a specific pattern to minimize display artifacts, which might otherwise result from interference generated by pixel inversion techniques performed during the pixel dithering. Astrolabium, User profile for user: Once I reinstalled the stock MS Windows 10 and the dithering was enabled in Windows 10 by default. And the eye strain / pain issue went away. I'd guess that amplitudes are lower as well. No promises . Unfortunately that particular unit gave me eye strain and I had to send it back. And it's contrast levels are so-so. Holy Cow those videos are enlightening to me. b) My vision being too poor to notice I did get eye strain from my S7 and S7 Edge but not neurological problems. 2.Disable dithering -> restart -> enable dithering = 100% success for the following cases. Previously in a material I would use Pixel Depth Offset and Dither Temporal AA to blend objects as seen here. chromatic pattern inuences the temporal sensitivity . Before the GPU sends data to the monitor, it can do stuff like dithering, but that's not something that you can capture in software. Site is running on IP address 172.64.80.1, host name 172.64.80.1 ( United States) ping response time 3ms Excellent ping.Current Global rank is 5,421,398, site estimated value 396$ Though he did not use the term dither, the concept of dithering to reduce quantization patterns was first applied by Lawrence G. Roberts in his 1961 MIT master's thesis and 1962 article. The nice thing is the it shows the email address of the person that committed the code (if you click on History, it's probably possible to access `git blame' somehow). It's a trade-off between a little distortion and much smoother looking pictures. I didn't just know it yet. Been trying to setup an OS X virtual machine on my desktop so I can speed up development of my GPU driver fix for Macboks (so I don't have to borrow my mother's MBP). 6Bit+Frc ) and much smoother looking pictures promise 'billions of colors ' they n't!
