# Using Dasung Paperlike HD-F and HD-FT with Raspberry Pi 4 | ||
|
||
_Note: I only have access to the Paperlike HD-FT, but if someone gets | ||
it working with the Paperlike Pro, I'll be happy to update my | ||
instructions._ | ||
|
||
The [Dasung Paperlike Pro / Paperlike | ||
HD](https://www.indiegogo.com/projects/first-e-ink-monitor-with-front-light-touch) | ||
are E-ink monitors that have many nice properties (and work well | ||
outdoors). | ||
|
||
They generally work with most HDMI outputs, but I had problems with | ||
the Raspberry Pi 4. The point of this repo is to document what I had | ||
to do to get it working (I can't fully tell which device is at fault | ||
here, but I suspect both the Pi 4 and the Paperlike have issues). | ||
|
||
What I did to make it work: | ||
|
||
1. extracted the | ||
[EDID](https://en.wikipedia.org/wiki/Extended_Display_Identification_Data) | ||
from the Paperlike on a iMac and included it as edid.dat, including it | ||
in the same directory as the `config.txt` (which is typically `/boot` | ||
but `/boot/firmware` on Ubuntu) | ||
|
||
2. forced the use of this using | ||
|
||
``` | ||
hdmi_edid_file=1 | ||
hdmi_cvt=2200 1650 40 1 0 0 1 | ||
hdmi_group=2 | ||
hdmi_mode=87 | ||
``` | ||
|
||
in `config.txt`. *Note:* it is now _incompatible_ with anything but the Paperlike HD. | ||
|
||
For convenience, I have included my `config.txt` and `edid.txt` this repo. |
