I tested better.

With Lenovo Thinkpad EDGE 15" and "VGA Intel Corporation Core Processor Integrated Graphics Controller (rev 02)" under Linux Mint, I confirm that I have the same problems reported from jaschenka. But it is an old notebook (an i3 CPU) and I'm operating near the limits of the HDMI controller.

With the desktop computer, a GeForce 9800GT, under Windows, it works correctly. So sorry for the previous FUD :-/

As already reported, the eink screen is (by construction) not very bright, but with a desk lamp at 45 degree respect the screen, it is perfectly readable also indoor.

I compared a PDF document in A2 mode using the native PDF reader under Android, and under Windows, using the HDMI connection. The Android version is only minimally better on some minor details like tables, and few capital letters. So the A2 mode is working in the same way under Android and HDMI connection.

Sadly the A2 mode introduces visible artifacts also in text of medium size, and it is a big compromise respect the wonderful EDP mode. Up to date the HDMI monitor application supports only the A2 mode. Summing up: I fell in love with the EPD mode, and barely satisfied by the A2 mode.

All applications with black-and-white/monochrome themes are extremely readable, and I'm happy with them. If there are very few gray levels it is acceptable. If the theme has too much colors, is IMHO not useable. In any case the text must be perfectly black, and the background white, otherwise there are too many artifacts.

For writing documents I think it is perfect. In case of IDE and coding some fine-tuning must be done on themes and so on. For example I tried IntelliJ IDEA with default theme, but it is not readable. I will report better in future... maybe reducing resolution, changing theme, etc...

The mouse is not very usable, but if you for writing or coding, you can use mainly the keyboard, so it is not a problem.

I had to play better with the resolution of the monitor, and I will report later. It seems that lower resolutions have better lags, and do not degrade the displayed details, because with higher resolution one has to increase any way the size of the fonts. So it seems that in lower resolutions is the internal HDMI driver performing scaling (taking advantage of the full resolution of the monitor), and the usability is better. But I had to experiment better.

Sincerely I bought the Boox mainly as external monitor, and I have doubts that the Dasung monitor works better in this usage scenario. But I never tried one, and the video on youtube can be misleading.
