Onyx Boox Launches $1,900 Boox Mira Pro Color E Ink Monitor
Onyx International has announced its new Boox Mira Pro color E Ink monitor, a 25.3-inch display that brings the company’s tablet-grade electrophoretic panels to desktop users. Priced at $1,900, the Mira Pro extends Onyx’s decade-long expertise in Android-powered e-readers into the workstation space, promising paper-like comfort, weeks-long standby life, and up to 4,096 colors on screen.

Design and Connectivity
The Mira Pro’s chassis is machined from anodized aluminum, measuring just 11 mm thick at its slimmest point. Its zero-glare, micro-etched front surface minimizes reflections under ambient office lighting, while the rear panel echoes the clean lines of Apple’s Studio Display. Connectivity includes two HDMI ports, a USB-C port with 65 W pass-through charging, and a DisplayPort input, making it easy to hot-swap between laptops and desktops.
Power Consumption and Efficiency Analysis
Color E Ink excels in static applications, drawing under 2 W when displaying a full-screen PDF or word-processing document—an order of magnitude lower than IPS or OLED panels. Dynamic refresh up to 15 Hz consumes around 4 W, still below comparable low-power LCDs. However, the bistable nature of electrophoretic media introduces ghosting artifacts: moving graphics leave faint trails unless a full-screen content refresh is triggered, which can take 300–400 ms per cycle.
Use Cases and Workflow Integration
Writers, note-takers, and researchers will appreciate the Mira Pro for extended reading and markup sessions. Its high pixel density renders crisp text in IDEs or desktop publishing tools, and its broad color gamut (up to 50% of sRGB) suffices for simple diagrams and charts. Onyx plans firmware updates to add on-screen annotation via third-party USB-C stylus input, enabling direct markup of PDFs without a PC intermediary.
Comparison with Alternative Technologies
Dasung’s comparable 25.3″ 33 Hz color E Ink monitor retails near $2,000 but uses the older Kaleido 2 panel, limiting color depth and contrast. Amazon’s Kindle ColorSoft and reMarkable Paper Pro tablets demonstrate the inherent trade-offs in color E Ink: muted tones and low motion clarity. By contrast, TFT/IPS displays offer full-speed refresh at the cost of blue-light emission and higher power draw. Sharp’s mono-chromatic Memory LCDs can achieve 60 Hz updates but lack any color support.
Market Outlook and Future Developments
At SID Display Week 2025, E Ink Corp. previewed Kaleido 4, promising 8,192-color panels with 30 Hz refresh, hinting at next-generation monitors later this year. Industry analysts like Ross Young forecast a gradual uptick in E Ink desktop displays, especially for sectors requiring eye-friendly interfaces—legal, education, and programming. Onyx itself has teased a 32″ color E Ink prototype at Computex, positioning the Mira Pro as the vanguard of a new low-power, high-comfort display category.
