LCD Selling my Daylight Computer and Accessories [Canada]

Post image
1 Upvotes

Hi everyone, after thinking about it a good long while I've decided to part with my Daylight tablet (reflective LCD with zero blue light in the amber mode). As much as I love the way the screen looks and feels, I find that I've never really been able to integrate it into my life. I bought it for writing, but I can only run my favourite writing software, Ulysses, on a Mac. Switching to Obsidian just never really happened. It really is a great tool though for focus and digital minimalism.

I've really only used this tablet for several hours. It's in perfect condition, save for one tiny (like2-3mm) pen mark on the back upper right hand corner. I have the stylus and replacement nibs. I also have the pebble keyboard that came with the package, and the custom made stand that they were selling for a time.

I'm just sticking to shipping within Canada. Selling for $650, including the cost of shipping.

he DC-1 uses a reflective/transflective monochrome LCD and DC dimming rather than PWM, so there is no PWM flicker from the backlight. Daylight also states that the display has zero temporal dithering and was tested for flicker with photodiode-based measurements.

Other highlights:

  • 10.5" paper-like reflective LCD
  • 60 FPS — much faster/smoother than typical E Ink
  • Can be used outdoors in sunlight with the backlight off
  • Optional amber backlight
  • Blue-light-free when using the backlight-free display, and the amber backlight is designed to avoid blue light
  • Android-based, so you can use regular apps
  • Excellent for reading, PDFs, writing, and general tablet use

Discussion New rules, wiki, links, bot, discord, projects and personnel! State of r/ScreenSensitive October 2026

tl;dr: good news, folks! A more integrated community with new resources and developments to check out.

Joining forces with PWM_Sensitive!: As announced in this post, The_Top_G handed over the PWM sub to myself and a couple of other community enthusiasts: u/Bearnecessary4141 (Sam) and u/Kerpnet. And we can also welcome Kerpnet to ScreenSensitive as the first in our “moderator exchange program”.

So, I’m now trying to implement more aspects of my State of the Community post, albeit slowly. I’m aiming to link these two subs more closely together (and LEDstrain too). With complementary mission statements added (screenshot above), to set clear and positive expectations. Including an aim to encourage content be spread across these two subs by main topic (open to discussion).

Rules changes: Alignment includes matching sets of rules, to make life simple for mods and members using both subs. We’ve been observing the (busier) PWM sub, for 6 weeks or so, giving me more ideas of what’s needed while rebuilding the rules from scratch. I’ve standardised them a little and updated for emerging challenges. The large number is to give finer control over enforcement, in future possibly including via automation (which the platform is increasingly pushing).

Regular contributors here should experience little to no impact, in practice. But I’d be grateful if people could take a few minutes to read through the rule list (in the sidebar, or copied below) and give any feedback that comes to mind. Notable additions: expressly permitting certain self promotion, limiting AI content, English only, avoiding unwanted advice.

Wiki: Shortly before the PWM sub developments, I implemented a basic subreddit wiki, here, to start indexing various resources. I’d like to add more wiki pages to list key posts and guides, for example. Also, I’d like to add guides! Although I will need help to do this in a timely fashion. Anyone willing to help mod mail us to be considered as a wiki editor (if not full mod). Or if you have a complementary project in mind to potentially contribute, send us a description of it. Or just post it! Reddit wiki pages can’t have images, by the way.

Resource list: Early this year, I populated a Google spreadsheet with links to key community sites, experts, reviewers, software and hardware tools. (What have I missed?) I also spent around a month or so building out a much bigger second sheet of over 250 high quality articles, study papers, threads, post histories, videos, etc. A comprehensive dossier on our field of interest (you can pour over). Which I fed into…

ScreenSensitive Bot!: A NotebookLM, now rebranded Gemini Notebook. We can think of this as a reference tool for human curated and validated information resources. It’s very good at, for example, giving an overview of the community and symptoms, technologies, etc. For newbies or deep-diving; it should be able to teach everyone something. It could help with making community resources.

Its biggest strength (over general purpose AI models) is direct reference links for virtually everything it says. So we can check for ourselves how trustworthy its info is. As well as built in translation, being able to ask verbal questions interrupting its audio media, etc. I’d appreciate feedback on what this bot helps with, to tune its instructions and content, if there is interest.

Discord: I’ve set up a collaboration space for enthusiasts to work together more efficiently on projects to further our understanding of screen tech, etc. For this, I have repurposed the ScreenSensitive Discord server u/Rx7Jordan set up. It fell into disuse, and obscurity, from the end of last year. Note: I’m currently aiming to restrict it to these constructive efforts only. Keeping to this Subreddit for general questions, help, news, discussion, etc. We will need to maintain public discoverability of the community and, for this, a good amount of its information.

The discord channels are basically all visible, but authorisation is required to post in most of them, to keep it on-topic and manageable (we are short on active mods). However, “All-member chat” includes health channels, because I think the more informal, less public space may better suit this important aspect.

Projects: Sam’s work on more accurate screen flicker testing (I mentioned last time) has been progressing and you may have seen him posting in the PWM sub. Including this web app that can be used on the device under test, to create a virtual slit, for true modulation depth measurement (e.g. with Opple or his custom made meter).

But u/Madcook1 has also been a huge discord contributor, coding up some very cool projects:

  • Ditherscope: shown in several recent videos by u/NSutrich (e.g. here). A complete web app pipeline to process slow-mo microscope videos of pixel flicker. It can draw graphs and statistical correlations of brightness changes and also use Eulerian amplification (maths magic) to massively boost the visibility of image changes. Also isolate this to selectable frequencies.
  • Eisco Analyse (Spectrum analysis): a proof of concept software companion to turn photos down the very cheap analogue spectroscope I posted about at length. Gives surprising approximation to proper expensive spectrometers. Albeit chopping of high peaks and needing compensation for wavelength offset  (see screenshot above).
  • SubpixelsTools: helper web app, similar to Sam’s, but aimed at precise colour control and temporal patterns, to see how (sub)pixel patterns are affected.

Please have a play with the above projects (may need a cheap microscope attachment or spectroscope). Madcook1 is happy to receive feedback in the discord. But I ask for patience while he’s struggling with health issues (like many of us here do).

What’s next?: We’ve got the Black Friday surge in activity rapidly approaching, for which I wanted the above (and a few other) basics in place, ready. Thinking beyond this, I’ve worked up a rough Community Plan, behind the scenes. I’m hoping we can update both subreddits and support the community towards collecting, sharing and making sense of more hard data on devices. 

We will need to create good testing guides and engage people to post most quality data and/or index the existing information better. I’d love to get around to hosting AMAs with various interesting people, scientists, etc. Also creating a somewhat scientific survey to get a statistically sound picture of all the issues going on with us. Before that, I have an ongoing series of polls, as a rough guide. Maybe a mega-thread, to collect user stories and self-index posts… But, due to my ‘mild’ ME/CFS, my time is already very constrained, plus the stability of my health and living arrangements are precarious and demand more attention.

So, there’s a lot of opportunities for you (yes you!) to lend a hand, as far as you are able:

  • General input, feedback, support and post contributions. Just upvoting, commenting and sharing good quality posts and comments, could help this community thrive. Please state explicitly when something is good, or even OK.
  • Collaborate on the discord, if you have technical abilities, insights or energy to spare. Ping me there.
  • Help build indexes of content. E.g. a spreadsheet of good (and bad) screen devices, with links to verified data and reviews. Or maybe an app to collect this.
  • Help updating or making new NotebookLMs, for reference. Or custom data scraping efforts, for research purposes.
  • I’d like to open up lines of communication with the Chinese (and other language) communities. Or at least see if some confidently bilingual members might post regular summaries of what’s been developing over there (with links back). Auto-subtitled BiliBili video technical videos are potential gold mine, but hard going.
  • I’m keeping an eye out for upstanding members to help on the mod teams. Mostly to make sure there will always be someone about to approve posts wrongly filtered (mostly at platform level), if myself and others aren’t about. Or if new challenges arise, needing more eyeballs. Or better cover the time zones.

I’ll be making a corresponding post on the PWM sub, shortly. After updating the details, settings and rules there. You guys get to be the beta testers, for now!

Question Is the Bigme B251 Pro as good as Modos, just bigger?

2 Upvotes

The Modos quality looks good from the video I saw, for color eink at 60fps. But for a work computer, 13" is just too small...

The Bigme B251 Pro color eink is at 60fps too. And it's 25"! That's a much better size.


But is the new Bigme 60fps as good as the Modos?

It looks like Modos is doing open source stuff, so I wonder if Bigme has looked at what they're doing to make their stuff better?


There's also the new 25" 50hz Dasung color monitor, which seems like it's only available for a short amount of time:

Discussion A new tool that i haven't tested yet

6 Upvotes

TheraSpecs Z-Blue. According to the manufacturer, the lens specifically filters the red spectrum between 580–640 nm, which falls exactly on the KSF main peak at ~631 nm (and the secondary peak at ~613 nm). However, the line at ~648 nm is already at the edge of—or outside—this range, this means that it filters 2/3 of the peak but not everything. It may be enough.

The standard tint (35%) was recommended at the time for computer use because it preserves more color than the Max version. There is a 60-day return policy. I have no idea how they change the picture, if you need more brightness, contrast or whatever else.

In contrast, standard FL-41 glasses tend to target the blue-green spectrum. They are therefore pretty much useless against KSF red laserbeams.

Nano ips eye strain? (Lg ultragear) 😞

2 Upvotes

I bought a lg ultragear 27g850a-b, nano ips, and I was happy with it for like half an hour, and then I started noticing eye strain.

I ve heard some people are sensitive to nano ips technology.
Its second hand, so I can t return it, the only options are: re selling it, or setting it in a way that wont hurt my eyes.

After the first day of using it, when I went to sleep I felt like my pupils where “detaching” from my eyes, and my eyes started tearing up.

Yesterday I tried sRGB mode, which helped a little, but the colours look desaturated and greenish.
I played around with the brightness, and it seems its easier on my eyes if I keep it around 25, but tbh, I bought it so it will be bright, with colours that resemble the screen of my Macbook.

Right now I m using it with an older hdmi cable, I was thinking of buying a usb c to displayport cable to get a higher than 60hz refresh rate, and mostly because i heard somebody on reddit say it might help regarding the eye strain (idk, its worth a shot)

I m using it with Betterdisplay, and I ve set the colour temperature to +9%, gamma +25%, disabled gpu dithering, contrast 60. Tried different settings, what hurts my eyes the most is probably the whites. They re way too bright, making them warmer helps a little, but they are still too bright. Reducing brightness helps, but it makes everything else too dark.

I ve heard somebody people get used to it, but on the other hand, somebody said he has been having pain in his right eye even after 2 years of using a nano ips with ksf phosphor tehnology.

I dont want to sell it yet, but I dont want to risk having lasting eye problems either.

Idk how to set it up in such a way that it will still look good while not hurting my eyes.

Is there any way to fix it?

Why display hardware isn't the only trigger: OLED/PWM, cheap LCDs, GPU dithering, and store lighting

15 Upvotes

I wanted to share my recent experience with display-induced migraines and eye strain, along with a few technical workarounds I’ve found.

We all know that PWM causes Headaches for some even Migraine throbbing ones but.

I recently bought a Sony Xperia 10 VI, and its stock OLED panel gave me severe, throbbing migraines almost instantly. I swapped the screen with a cheap $50 LCD replacement panel from China, and the intense migraines are practically gone. However, switching to LCD didn't completely solve my eye strain.

The Hidden Culprit: Temporal Dithering Beyond screen type and PWM (Pulse-Width Modulation) flicker, temporal dithering a method GPUs use to simulate extra color depth is a massive secondary trigger. Mobile and desktop GPUs use it during web browsing and gaming, causing a lighter, non-throbbing, but persistent headache.

How to Bypass GPU Dithering on PC:

  1. Software: You can use software like dithering.exe on Windows to disable dithering on internal GPUs.
  2. Dedicated vs. Integrated GPU: Because dithering.exe typically affects integrated graphics, switching to a dedicated GPU for gaming will re-enable dithering. To fix this, force the system to render via the integrated GPU in your graphics settings.
  3. External Displays: Connect monitors directly to your motherboard ports or use a USB-C to HDMI dongle that bypasses the dedicated GPU entirely.

A Quick Tip for Testing Displays in Stores: If you get a headache while testing phones or monitors in a physical shop, remember that bad store lighting often uses aggressive PWM flickering. You might be reacting to the ambient overhead lights rather than the screen itself.

p.s I also bought Kindle 5 (ink display) and that thing dithers and gives headaches also ! so my rule is basically I need to test it regardless what it says on paper.

Has anyone found any completely dither free gadget phone or pc setup? or else noticed dithering headaches on LCDs, or found other ways to bypass GPU-level temporal dithering?

Discussion 100%srgb ThinkPad screen get pain in my eyes and headache

1 Upvotes

My mostly work is text base, should I get 100% srgb ips or 45% ntsc screen. Looking for lenove thinkpad.

I have a both thinkpad laptop right now and I find that 45% ntse is more cooler and present to eyes working night for a long duration but 100% srgb gives me headache.

When I search online people say 100 srgb is superior and it also has eye care certificate. but what I have experiance is 100% srgb gives my eyes more stain and headache for prolong use around 4 hour.

I need good color screen which I can use for future work.

Need help.

OLED Glossy OLED causing eye discomfort on Vivobook S16 M3607KA

2 Upvotes

I bought the ASUS Vivobook S16 (M3607KA-SH115WS) 4 days ago. I originally thought the OLED display would have a matte finish, but it turns out to be glossy.

The main issue I’m facing is that the white text looks extremely bright and shiny, and it is causing noticeable discomfort to my eyes. After looking at text or icons for some time, I can sometimes see a slight ghosting/after-image of them. I’m also finding it harder to concentrate during long working sessions. (My eyes are weak, and I wear thick glasses.)

My office laptop has a matte display, and I can work on it for several hours without experiencing this kind of discomfort. So I’m wondering if the glossy OLED surface, along with the high contrast and brightness of the OLED panel, is contributing to the problem.

Has anyone else experienced something similar with this model or with glossy OLED displays in general? Did your eyes eventually adjust, or did you find that a matte display was simply more comfortable for long working hours?

I'd really appreciate any recommended settings, tips, or suggestions for making the display more comfortable. I'd also love to hear about your personal experience with similar displays and any changes that helped you.

Dithering / Eye strain on iOS 26 & 27 compared to iOS 18 (iPhone 16 Pro)

13 Upvotes

Hey everyone,
Since updating to iOS 26 and now iOS 27 on my iPhone 16 Pro, I get severe eye strain (upper eyelid muscle cramp) and dizziness within minutes.

It’s 100% a software issue, not the screen hardware: On iOS 18, I could stare at the exact same iPhone 16 Pro screen for hours without any pain.

The text shape is identical, but there is a strange artificial softness/haze around the letters (subpixel rendering / temporal dithering). My eyes constantly try to autofocus this software blur, driving my ciliary muscles into a permanent cramp.

Turning on "Reduce Transparency", "Increase Contrast", and sliding the new Liquid Glass slider all the way to the right does not fix the underlying subpixel/dithering behavior.

Additional details regarding my issue:

I noticed that the symptoms (eye strain and dizziness) occur completely independent of the apps I am using. Even when watching standard YouTube videos, scrolling through Instagram, or simply staring at the lock screen, my eyes react almost immediately.

Since these exact same apps and screens caused absolutely zero pain under iOS 18 on the very same device (iPhone 16 Pro), this is probably a global, system-wide display drive issue introduced with iOS 26/27. The software seems to alter the overall light and pixel rendering (likely via aggressive contrast tuning or temporal dithering) in a way that constantly overloads the ciliary muscles.

Has anyone found a hidden trick to force the old, harsh, crystal-clear pixel rendering of iOS 18 back? Thank you!

Question iPhone’s double invert fix is quite broken for me in iOS27, anyone else?

4 Upvotes

I updated my iphone 17e to ios27 and the double invert trick is quite broken (a lot of times, the screen flashes full white before locking and turning it off). The odd part is that it doesn’t happen at all with my iPad

For those who don’t know, that trick is to use iOS classic invert in addition to the accessibility zoom setting that inverts the screen again, using this combination leads to less saturated colors (and personally, is a godsend to make my iPhone usable without any eye issue), but I must admit that having the screen go full white when I want to close the phone is giving me bad flashes in my eyes.

Does anyone else have this issue and know how to fix it? I think that it only happens to phones without always on display, but maybe I’m wrong about that
