To do this, right-click somewhere on the desktop and it's the first option in the context menu. It is a good laptop, I really like it. Although I'm leaning towards the former rather than the latter. Both have resulted in eye strain issues whereas with my 5 year old cheaper monitor I have had no issues. 5- do you have any resources for this (is it really temporal dithering? (Or is this a question that depends on which vendors display panel gets put in the laptop? Does it use Intel Graphics, or NVidia or AMD video? If I use a true 8bit display would that mitigate any dithering? Would using an 8 or 10 bit monitor make any difference? One person said they had an MRI done on their eyes. but my current laptop is perfect and I can use it for many hours per day with no eye strain or migraines. A search for "dithering" on Android source code shows several results. I'd guess that amplitudes are lower as well. From reading online the culprit seems to be temporal dithering. If there's one thing I've learned on this forum is that our problem is largely unknown. It's possible this "eye strain" is something no one has been able to identity. Grumble grumble. I will frequently update this thread with resources and interesting finds. 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. I got terrible eye strain and headaches from using the computer for a few hours. It's a trade-off between a little distortion and much smoother looking pictures. u/dogelition_man I have tried the novideo_srgb and a few other apps like it. In UE5 nanite objects just turn grey when I apply this shader and regular objects create intense noise as seen in the attached gif. ryans No. Unfortunately that particular unit gave me eye strain and I had to send it back. , 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?). By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. From what users have mentioned, PC versions/builds running a comperable graphics card can have temporal dithering disabled but on mac OS it cannot be. Apple support advised me to leave feedback. I discovered that I could suddenly work whole day on my computer without significant eye strain. One of the suspect of the cause of the eye strain is dithering / temporal dithering. No, there is an actual deep underlying technical malfeasance that most people don't understand, and the problem is for people with sensitive eyes, another thing most people won't understand. chromatic pattern inuences the temporal sensitivity . If unlucky then need to repeat step 2. http://androidxref.com/8.0.0_r4/search?q=dithering&defs=&refs=&path=&hist=&project=art&project=bionic&project=bootable&project=build&project=cts&project=dalvik&project=developers&project=development&project=device&project=docs&project=external&project=frameworks&project=hardware&project=kernel&project=libcore&project=libnativehelper&project=packages&project=pdk&project=platform_testing&project=prebuilts&project=sdk&project=system&project=test&project=toolchain&project=tools. Adjusting the brightness doesn't help. Inflammation of your eyes; Eye inflammation may cause blurry vision and migraine. I'm just concerned that getting a newer monitor won't help, as I am seeing other people with this issue say so. JTL 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(?). Algorithms 3.1. I also don't understand how a refresh rate of 60 Hz would lead to just 30 Hz polarity inversion (shouldn't it be 60 Hz, too?). The problem is that only a minority of the population seems to be severely affected. Apple would probably consider dithering as an Accessibility issue, but I don't know about Google. When . If those GPUs actually have undefeatable dithering built into their output, that would be a terrible design flaw. ), https://ledstrain.org/d/1048-new-graphics-card-rtx-3090-gives-eyestrain/2, https://ledstrain.org/d/1524-eye-strain-with-new-gpu. Also, please share with us: 1- your experience and symptoms. More than a million books are available now via BitTorrent. http://www.eevblog.com/forum/testgear/beginner-needs-to-record-dignals-from-a-display-backlit/?all, https://lists.freedesktop.org/archives/intel-gfx/2011-October/012464.html, https://lists.freedesktop.org/archives/dri-devel/2017-September/153449.html. There is definitely something going on. IIRC for such displays color depth checks are done to see if temporal dithering is needed to create the illusion of 8-bit colors. The eyeballs feel like they are burning or like someone is stinging them with needles, especially when I close my eyelids and the pain does not go away many hours after I quit using the device. Of course, on top of that, the monitor could then be doing its own dithering. TEMPORAL DITHERING Dithering is a technique to compensate for missing color values to increase the perceived amount of color and shading. From a reliability and performance perspective I wouldn't want to but this is too much, for a daily computer for creative work. :(. 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. 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. To start the conversation again, simply ask a new question. So is this one of the reasons there's some thinking around here that refresh rates above 144Hz could ease strain for basic computing, not just gamers? Can't even find any place saying what it's bit depth is. I'd be interested in hearing what others think, and most importantly if anyone has caputred the snow artifact on camera, or whatnot, Just saw this on the FreeBSD forums (seems the technical people there are misguided about the problem), https://forums.freebsd.org/threads/eye-strain-from-certain-video-modes-drivers.53468/, Hi, a simple explanation about what dither is: bjango.com/articles/1pxisnotenough/, http://nouveau.freedesktop.org/wiki/Dithering/. It's like all the muscles in my faces and back have gotten frozen from pain, and it's been almost a week since I pulled the card out. There are some of us that are worried we won't be able to work in a few years because of this. - It seems the folks at Dell have figured out how to disable dithering. 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). 1-800-MY-APPLE, or. 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. Here is the above mentioned email to the amd-gfx list. Either way, you should be able to turn it off completely in novideo_srgb. Research shows that a slight rose tint reduces eye strain greatly. https://lists.freedesktop.org/archives/dri-devel/2017-September/153449.html (search "dithering"). It seems there are a growing number of people affected by this. intensities that are integrated over time by a sensor (eye or camera) to produce the desired brightness value. if it's a 8 + 2 bit FRC monitor, make sure to run it at 8 bit and not 10 bit). 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. If this trend is continuing the way it has, pretty soon we are out of options when it comes to purchasing a new device which does not get us eyestrain. My struggle with this new screen was to the extent that after using the computer for ~4 hours , it felt like I could see but my mind could no longer properly process what I was seeing! 1.Disable dithering -> shut down -> turn on PC -> enable dithering = 100% success. This seems to be the case with Apple's M-series computers because if earlier there was an option to switch from "Billions of colors" to "Millions of colors" by using Stepane Madrau's SwitchResX then now it just shows "Billions of colors" as the only option: . Here is the culprit as far as I've gotten with little information and no solution: Based on the symptoms and collective user feedback it seems like the issue comes from temporal dithering. More Injection therapy with a long lasting local anesthetic and a steroid, sarapin, or prolotherapy. Press J to jump to the feed. u/BloodyHell619 have you found a solution to this problem? I have a Late 2019 MBP 16" and I am experiencing very similar symptoms and issues. in South Korea gives some weight to the notion that curving a screen can be beneficial in reducing visual fatigue and eye strain. Biofeedback if clenching related. This gave me an idea to try to run a virtual machine on my computer: I have a Mac but I think it should work the same with a PC laptop with VirtualBox or Fusion or whatever else. A method and system for temporal dithering of pixels in a display 14. Try hard-refreshing this page to fix the error. Indeed when I use an external monitor with my MBP 16" it has the same stressful result on my eyes. For more information about this format, please see the Archive Torrents collection. Dispersed dot ordered dither l c The term ordered dither refers to . AFAIK, with full range RGB output, the "default" dither setting should be off, and with limited range it'll apply dither.

(dithering) I was going to look into it. I am 31, never had glasses, consider myself to have great vision and after a few minutes or prolonged use on the MBP 16" my vision starts deteriorating in a very scary way. That version gave me really bad eye strain. Temporal dithering (FRC - Frame Rate Control) FRC (Frame Rate Control) or temporal dithering, . In response to Astrolabium. At least with the Intel Iris graphics. I have a feeling understanding all this is vital to understand possible eye strain effects of temporal dithering. For example AUO 18 bit TFT Panels have an unpleasant "flashing" effect due to a poor dithering algorithm. vinkenvvt That source is quite old (~2004). After implementing the hardware circuits for a multidisplay system on a FPGA device, we find that our spatiotemporal dithering method is .
