An e-ink monitor can be a superb second screen for text and a frustrating main display for almost everything else. The technology is reflective, calm in bright ambient light, and efficient when an image barely changes. It is also slower, duller, and far more expensive than a good LCD.
My buying advice is simple: start with a 13.3-inch Dasung if you want to test the idea. Move to a 25.3-inch BOOX, Dasung, or Bigme only if text-heavy work already justifies a four-figure display. Do not buy one because a manufacturer promises medical relief. This is consumer-tech analysis, not medical advice, and these products do not diagnose or treat eye conditions.
Prices below were fetched on July 24, 2026. They are US-dollar store or list prices before shipping, tax, import fees, and currency conversion. I have not used these monitors, so every speed, colour, and comfort claim is attributed rather than dressed up as hands-on experience.

Those speed numbers are not directly comparable to an LCD refresh rate. E Ink has slow pixel transitions and uses refresh processing to trade ghosting against motion. A higher claimed frame rate can make a cursor move more smoothly while text smears or old content remains faintly visible. Treat every headline number as a mode, not a promise of LCD-like motion.
Current prices and the size premium
Dasung’s official store listed the 13.3-inch monochrome Paperlike 13K from US$679 and the colour model at US$749. Its 25.3-inch colour Paperlike started at US$1,698. The monochrome 25.3-inch model showed sold out, so I have not treated it as a current recommendation.
Bigme’s store listed the B251 Pro at US$1,349, reduced from US$1,599 at the time of this check. The BOOX Mira Pro Color product page remained live at a US$1,899.99 list price reported at launch. Those are large gaps for panels with the same 25.3-inch diagonal and 3200 x 1800 resolution.
The lower price makes Bigme the obvious 25-inch value candidate on paper. It does not make it the safest purchase. Return policy, panel defects, firmware support, shipping, and warranty logistics matter more at this price than a small difference in ports. Read the store terms for your country before importing.
Dasung: the practical 13.3-inch choices
The Dasung Paperlike 13K monochrome model is the most sensible entry point. Its 3200 x 2400 resolution works out to 300 PPI, which is much sharper than the 145 PPI large panels. Dasung claims up to 37 Hz. The format is small for a primary desktop monitor, but it is large enough for a document, terminal, reference window, or distraction-free writing pane.
Choose the US$679 monochrome version when text is the job. It avoids Kaleido’s lower effective colour resolution and darker-looking background. Choose the US$749 colour version only if syntax highlighting, charts, status colours, or annotation cues materially improve the work. The extra US$70 is modest beside the full purchase, but washed-out colour is still washed-out colour.
The 25.3-inch Paperlike Color Revolutionary gives you the large canvas at a US$1,698 starting price. Dasung lists a Kaleido 3 panel, 3200 x 1800 resolution, and a claimed 33 Hz refresh mode. The larger 145 PPI image will not look as crisp as the 13K at close distance. Use the viewing-distance calculator before assuming a physically larger screen belongs closer to your face.
BOOX Mira Pro Color: polished but expensive
The BOOX Mira Pro Color is the easiest premium model to understand. It has a 25.3-inch Kaleido 3 panel, 3200 x 1800 resolution, 4096 colours, 16 gray levels, dual-tone front lighting, dual speakers, and a stand that tilts, pivots, and offers 50 mm of height adjustment. Ports include HDMI, Mini HDMI, USB-C, DisplayPort, and DC power, plus a 75 x 75 mm VESA mount.
BOOX is unusually candid about the central compromise: its official page says faster refresh produces more ghosting. Four preset modes let you lean toward speed or text clarity. That flexibility is useful, but it means there is no single best setting. Scrolling, typing, reading, and video ask the panel to make different compromises.
At US$1,899.99, this is the expensive option. It costs US$550.99 more than the Bigme sale price and US$1,150.99 more than Dasung’s portable colour model. The stand, mature controls, five ports, and BOOX software may justify part of that premium. They do not turn 4096 muted colours into a colour-critical editing display.
Bigme B251 Pro: the value bet with an unverified claim
The Bigme B251 Pro is the most interesting large e-ink monitor tonight because its US$1,349 store price undercuts BOOX and Dasung. It has a 25.3-inch colour panel, 3200 x 1800 resolution, 145 PPI, 4096 colours, 16 gray levels, adjustable warm and cool front lighting, HDMI, DisplayPort, wireless mirroring, a remote, and portrait support.
The headline is “up to 60 FPS.” Bigme states it, but I could not find independent measurements confirming 60 distinct clean frames per second with latency, ghosting, and image quality documented. Tom’s Hardware also labels the figure as a claim and notes that slow pixel response, latency, ghosting, and motion quality remain concerns.
There is another catch: Bigme’s listed USB-C port is for system upgrades only. It is not the one-cable laptop dock people expect from a modern office monitor. Video comes through HDMI or DisplayPort. That is not fatal, but it belongs in the buying decision.
The queued Bigme B251 Pro launch analysis will examine the new model separately once independent testing appears. Until then, buy it for price and features, not for an unverified frame-rate record.
What E Ink still does badly
Video, gaming, animation, dragging windows, and rapid scrolling are still bad fits. Fast modes improve motion by accepting ghosting or reduced detail. A manual or automatic full refresh clears the residue, often with a visible flash. If that behaviour will irritate you more than LCD light does, an e-ink monitor is an expensive way to discover it.
Colour E Ink is also not normal monitor colour. The large models advertise 4096 colours, while conventional displays reproduce millions. Saturation is muted, gradients can band, and Kaleido’s colour layer lowers effective colour detail. Use it for colour labels and basic charts, not photography, video grading, design approval, or any task where a subtle colour difference carries money.
Front lights need honest framing. E Ink can reflect ambient light, which is its defining strength, but these large colour panels often look dark without added illumination. Their adjustable front light shines across the surface rather than through it from behind. Some buyers prefer that. It is still emitted light, and no product configuration guarantees comfort for a particular person.
Finally, software matters. E Ink rendering benefits from per-application modes, contrast controls, refresh shortcuts, and operating-system tuning. A high-resolution Mac interface with translucent effects and animation is harder to render cleanly than plain black text on white. Budget setup time as well as money.
Who Should Skip This
Skip every model here if you need one display for meetings, video, gaming, colour work, and fast general computing. A good 27-inch 4K IPS monitor costs much less and handles those jobs with fewer compromises. The site’s gaming versus office monitor guide explains why refresh behaviour and connectivity matter more than a health label.
Skip the 25-inch models if you have not used E Ink as a computer display. A US$679 13.3-inch model is still expensive, but it limits the cost of learning whether ghosting and slow motion are acceptable. Buying the biggest panel first is not a commitment strategy. It is a four-figure gamble.
Skip the category if the purchase is meant to replace an eye exam or address unexplained symptoms. The research does not support treating an e-ink monitor as a medical device. The blue-light glasses evidence is a useful reminder that a plausible screen story and a proven outcome are different things.
Frequently asked questions
Can an e-ink monitor replace a normal monitor?
For text-heavy writing, coding, documents, and reference work, possibly. For video, games, animation, rich colour, and quick window movement, no. Many buyers will be happier using E Ink as a second display.
Is colour E Ink as sharp as monochrome E Ink?
Not for colour content. Kaleido overlays a colour filter, so black-and-white resolution and colour resolution differ. The 13.3-inch Dasung 13K has a sharper 300 PPI monochrome image than the 145 PPI large panels.
Does a 60 FPS claim mean an E Ink monitor behaves like LCD?
No. Frame output is only one part of motion. Pixel response, latency, ghosting, cleanup refreshes, and image detail determine what the result looks like. Bigme’s 60 FPS figure needs independent verification.
Do E Ink monitors have blue light?
The reflective panel does not require an LCD-style backlight, but models with a front light still emit light and may offer cool and warm settings. Ambient room light also contains blue wavelengths. The practical distinction is how the display creates a visible image, not a promise of zero blue light.
The Short Version
Buy the US$679 Dasung Paperlike 13K B&W if you want the lowest-risk e-ink monitor experiment. Buy the colour 13K at US$749 if colour cues matter. Among the large models, Bigme’s US$1,349 B251 Pro is the price leader but its 60 FPS claim is unverified; Dasung starts at US$1,698; BOOX is the polished US$1,899.99 choice. All remain specialist text displays with ghosting, motion, colour, and setup compromises.
