A review from one year ago https://the-digital-reader.com/2016/05/16/second-gen-dasung-... the price tag seems to be $1300

For an older model, which didn't have HDMI. The linked blog actually discusses Dasung's third-generation product at https://the-digital-reader.com/2017/06/02/dasung-paperlike-p... and mentions that the previous gen's product price was $700 on Indiegogo, and says they don't know what this unit's price will be.

If you wish to use an e-ink screen to avoid eyes strain, I've recently learned that a video projector does have the avantages of a classic monitor (colors, good refresh rate) without having to watch directly at the source of light, thus avoiding eyes fatigue. I consider it to be a better tradeoff than working with an annoying delay as if you were using a 10 years old computer.

How does backlit of reflected make a difference? Light comes of the screen/projection and hits the eye. I don't see how the light would change with that bounce by projection.

Yup, and a projector can provide a huge surface to work with - problem is that they are limited in resolutions available, and 4k ones are extremely expensive.

I guess that depends on how strong your projector is, because the light bounces of the wall/screen back in to your eyes.

Here's their real website: http://www.dasung.com/english/ I cannot wait for the day when large e-ink displays are cheap, or as cheap as normal screens, and have faster refresh rates.

I just want an 8.5" x 11" version that is portable, runs Linux, and can open PDFs. For reading papers you wouldn't be able to beat it.

Sony makes one, https://www.sony.com/electronics/digital-paper-notepad for $700 but it's a product being sold to consumers, so tinkering with the underlying OS (reputed to be Linux, in the form of Android) isn't supported.

(There are a number of other 8.5"x11" eink PDF readers out there.)

Gosh. I would buy this in a second if the price was a bit less and I was sure the durability/lifespan was good. The reduced eye strain benefits. I really want this.

What's the mechanism of action behind the reduced eye strain, and why is e-ink needed to achieve it?

Lack of flicker? True of any non-PWMed monitor.

Reduced brightness or contrast? Conventional displays can be turned down to match e-ink.

Lack of subpixels? High DPI displays make subpixels invisible under normal circumstances.

Smoother spectrum white? I doubt this makes a difference, but it's not completely implausible, because the eye does have some chromatic aberration. But greyscale LCDs are available.

Lack of polarization? Polarization is visible (see https://en.wikipedia.org/wiki/Haidinger's_brush ), but it's a very minor effect. It seems unlikely that something so difficult to see could cause eye strain. OLED displays don't show this effect.

It's notre direct light - starring at the sun (extreme example) severly hurt your eyes while watching at shadows is not a problem.

I was an early backer of their last USB based monitor, it is truly useless - very poor refresh rate, highly overpriced, poorly written drivers, clunky construction and the list goes on and on.... it ended up as quite a large waste of money. However, I do hope that the new version will succeed, I love reading on eink screens and I truly wish I had a decent, high resolution / DPI, fast refreshing eink display that woul…

Hey a sibling backer!

I agree, it quickly became a gimmick, and such has been face down on a counter top since I got it.

It is slow, it seems to use more CPU, and the stand that came with it is a joke. At least they had VESA mounts on it, that kept me interested another week.

One problem is that it gets this greasy look after an hour or so and you have to manually interact with it to clear it up with the buttons.

It would be nice to use an existing display cable, HDMI, DP, whatever, and plug it in without a further thought. Let the GPU shuffle the bits around the wire.

For a non-PWMed high DPI monitor adjusted to match the e-ink's brightness and contrast, the only difference in the light hitting your eye is the spectrum and the polarization. It's not completely impossible for these to matter, because of interactions with optical imperfections of the eye, but I've never seen any evidence that it actually does matter.
