Onyx Boox launches $1,900 color E Ink monitor for PC and Mac, but color E Ink remains a compromise

Onyx International, best known for its Android-powered E Ink tablets, has announced the Boox Mira Pro, a $1,900 color E Ink monitor designed to connect to PCs and Macs. The 25.3-inch monitor features a 3200×1800 resolution and a 16:9 aspect ratio, utilizing E Ink Kaleido 3 technology capable of displaying up to 4,096 colors. While the device boasts a range of ports-including full-size HDMI, mini HDMI, USB-C, and DisplayPort-and a design reminiscent of Apple’s Studio Display, it also comes with several compromises typical of color E Ink. These include washed-out colors, low refresh rates, and a grainy appearance, issues that are less pronounced in traditional black-and-white E Ink displays. The monitor offers four presets to adjust image quality and refresh rate, though faster refresh rates increase ghosting. Onyx International’s Boox devices are notable for combining the eye-friendly aspects of E Ink with access to multiple content sources via Google Play, distinguishing them from single-ecosystem devices like Amazon’s Kindles. The color E Ink monitor market remains small, with only a few competitors such as Dasung and Acogedor offering similar products. Potential buyers in the US should also be aware of possible import tariffs, as these monitors are currently shipping from Hong Kong. Overall, the Boox Mira Pro represents an ambitious step forward for color E Ink, but the technology still faces significant technical limitations compared to conventional LCD or OLED monitors.
