E-ink monitors have quietly turned into a real category. The BOOX Mira 25.3 and the Dasung Paperlike 253U are on desks people actually work at, not just in demo videos, and the software you run on them decides whether the experience feels calm or maddening. We spent a week working full days off two e-ink monitors and tested the seven desktop apps that make the setup worth the price tag.
What to look for in an e-ink monitor app
The apps that matter fall into two buckets: control and content.
- Control apps tune the monitor itself, refresh modes, contrast curves, ghosting removal, dark mode inversion.
- Content apps play to e-ink’s strengths, static text, minimal animation, low bandwidth, and let you avoid the interfaces that trigger constant partial refresh.
- Font hinting matters. Some apps antialias in ways e-ink hates.
- OS integration. On macOS especially, apps that respect system dark mode auto-switch cleanly to inverted mode when you go into dark.

1. BOOX Assistant — Best control app for BOOX monitors
BOOX Assistant is Onyx’s own utility for the Mira and Mira Pro. It handles the two things that make or break the setup: refresh mode switching (Normal, Speed, A2, X mode) and inversion for dark UIs. Without it you’re stuck in whatever mode the monitor’s front panel is on.
Recent versions added per-application profiles so a browser stays in A2 mode while your PDF reader stays in Normal.
Where it falls short: the interface is minimal to a fault. Some settings only expose themselves after digging into an advanced tab.
Download: BOOX Assistant
Bottom line: required software if you own a BOOX monitor. Not optional.
2. Dasung Control Panel — Best for Paperlike owners
Dasung Control Panel does the same job for Paperlike monitors. Refresh mode, contrast, backlight (on models that have one), and the FAST/A2 toggles all live here.
Dasung has been quieter on software updates than BOOX has, but the app is stable and the basics are covered.
Download: Dasung
Bottom line: the second half of your Paperlike setup. Grab it the day the monitor arrives.
3. Calibre — Best e-book library manager
Calibre is the de facto standard for managing an e-book library. It converts between formats (EPUB, MOBI, PDF, AZW), edits metadata, syncs to almost every reader, and includes a built-in viewer that works well on e-ink.
For an e-ink monitor workflow, its viewer is what matters. It’s calm, it doesn’t animate, and it respects font hinting settings you configure once.
Where it falls short: the main library UI is dense. New users bounce off it.
Download: Calibre
Bottom line: the library engine behind most serious e-reader setups.
4. SumatraPDF — Best minimal PDF reader
SumatraPDF is the anti-Adobe. It opens PDFs (and EPUB, MOBI, CBZ, DjVu, XPS) fast, does nothing you didn’t ask for, and looks good on e-ink because it doesn’t try to look good on anything else.
Keyboard-first navigation means fewer accidental scroll events, which means fewer full refreshes.
Download: SumatraPDF
Bottom line: open a PDF and forget the app exists. That’s the goal.
5. KOReader — Best long-form reading experience
KOReader started on Kobo and Kindle jailbreaks and grew a desktop build along the way. It’s the reader most e-ink monitor owners eventually settle on for long-form reading because it exposes every setting you care about: line spacing, margins, font weight boosting, hyphenation, and page-turn animation (off).
Where it falls short: the desktop UI shows its Linux-first roots and takes time to learn.
Download: KOReader
Bottom line: power-user reader for people who tune settings until reading feels right.
6. Adobe Digital Editions — Best for library e-books
Adobe Digital Editions is unavoidable if you borrow ADE-DRM’d books from a public library through OverDrive or Libby’s desktop path. It’s ugly, it’s slow, and it’s the only path to open those specific files.
Use it as a middleman: check the book out, download it, then read it in Calibre’s viewer (with a plugin) or a KOReader-compatible format.
Download: Adobe Digital Editions
Bottom line: install it once for library files. Ignore it the rest of the time.
7. Kindle for PC — Best for Amazon-purchased ebooks
Kindle for PC is Amazon’s official desktop reader. It handles your purchased library, syncs your position across devices, and works fine on e-ink monitors as long as you turn off animated page turns.
Where it falls short: it’s locked to Amazon’s ecosystem and to Amazon’s typography choices. Font hinting can’t be overridden.
Download: Kindle for PC
Bottom line: required if your books are on Amazon; skip if they aren’t.
How to pick
- You just bought a BOOX Mira. BOOX Assistant, Calibre, SumatraPDF. Done.
- You just bought a Dasung Paperlike. Dasung Control Panel, Calibre, SumatraPDF.
- You read long-form and tune everything. KOReader.
- You buy ebooks from Amazon. Kindle for PC. Nothing replaces it for that library.
- You borrow from the library. Adobe Digital Editions as the ingest step, then read in Calibre or KOReader.
FAQ
Which desktop OS handles e-ink monitors best?
Windows has the best control-app coverage from both BOOX and Dasung. macOS support has improved and now covers most core features; Linux support depends on the specific monitor and is mostly community-maintained.
Can I use an e-ink monitor as my primary display?
For text-heavy work (writing, coding, reading), yes. For anything with continuous motion (video calls, gaming, video), no. Most owners run e-ink as a secondary display and switch focus to it.
Do these apps work with reMarkable?
reMarkable ships its own desktop app for its tablet workflow. The apps above are for e-ink monitors that connect over HDMI or USB-C to your desktop, which is a different category.
