I got the smaller Dasung about half a year ago, I posted a comment about it here: https://news.ycombinator.com/item?id=29429093

Let me know if you have any specific questions.

Thanks!

* Do you use it as your main daily monitor?

* I find screen time quite addictive (which is one reason why I am on HN so much). Do you notice any difference from this perspective when using an eink screen?

* Has the screen quality degraded over time?

* How big a difference has it made to your life?

Let's see:

* I use it daily, but really only for my shell, including vim for coding/writing configs. Depends on the day, sometimes I spent more time in the shell than in the browser, sometimes it's mostly browser (and thus plain old screen, not E-Ink).

* I think that's hard to say since my main screen is so much larger. I did notice a difference in the evening between a tablet with Youtube vs a Kindle with a newspaper or a book. Although I do remember one or two evenings where I turned off the main screen and only used the E-Ink screen - I think there it helps with going to sleep later due to less blue light.

* I haven't noticed any degradation so far.

* I like it. I've barely had problems with eye strain anymore and eye strain was the main motivation for getting it. It's also just a bit larger than my laptop, so it's great when I travel somewhere where I'll use my laptop a lot since I'll get a second screen on the go/for the hotel room/etc.

I can't speak to e-ink but regarding screen time addiction, I used Gray-Switch (https://play.google.com/store/apps/details?id=com.vegardit.g...) to turn my phone display black and white, and immediately my phone use decreased by 66%.

I do this too on my iPhone - like all the really good iPhone settings, it’s an accessibility option, under Display -> Color Filters. You can also set up the “accessibility shortcut” so triple-clicking the side button enables or disables it.

It really reduces the intensity of the phone - you never realize just how garish the color choices are for almost every app out there until you see it in B&W.

This is a genius idea, I'm trying it out now. Had an iPhone for years and never had a clue about this feature. Thank you.

Thanks for sharing this.

This is now built in to newer versions of Android (I think 11+, and AppleOS may also have it).

where would the settings for that be? accessibility?

On my phone it's Settings => Display => LiveDisplay => Reading mode ("Grayscale mode for long-term reading"). I can also add a reading mode toggle button to the quick settings in the notification bar.

The search box in Settings will probably find it if you search for gray or reading.

This is on LineageOS 18 (Android 11), though I recall it being mentioned in some Google events/announcements so I'm 99% sure it's a core Android feature and not something specific to LOS.

thanks
