Dasung monitor: http://www.dasungtech.com
It is a good e-ink monitor. It can connect with my laptop through HDMI. It doesn't have any built-in lights like Kindle Paperwhite or Kindle Oasis. That's a problem which can be solved by using a lamp to beam the light onto the screen. With the right angle, it gives me the same feeling as when I use Kindle. The font size is also a problem. The default font size of my Debian + Awesome WM is too small on a Dasung monitor. I have to manually increase the font size of several programs when I use it, but it's okay. The other sad thing is that the refresh rate is still slow, so you have to be patient. There is no problem with text-based programs, which is what I use most. There is also an issue about the ghosting. I can bear with it. I use the Dasung monitor as my primary monitor for a year or so already. It's perfect for my eyes. I wish the new model of Dasung will be better.
Pro tips
With e-ink monitor which doesn't have color yet, you should set all your programs to have the white background color and black foreground color as much as you can. For websites, e.g., pantip.com, which use a dark background, you can change their styles using Stylish, a Firefox add-on, as you can see from an example here: https://github.com/pchaitat/stylish-pantip-dasung-paperlike-pro
