But that isn't stopping device manufacturers from exploring the technology, and today, Onyx International has announced that it has a $1,900 color E Ink monitor that you can connect to your PC or Mac. The Boox Mira Pro is a 25.3-inch monitor with a 3200×1800 resolution and a 16:9 aspect ratio, and it builds on the company's previous black-and-white Mira Pro monitors. The Verge reports that the screen uses E Ink Kaleido 3 technology, which can display up to 4,096 colors. Both image quality and refresh rate will vary based on which of the monitor's four presets you use (the site isn't specific about the exact refresh rate, but does note that "E Ink monitors' refresh speed is not as high as conventional monitors', and increased speed will result in more ghosting.") The monitor's ports include one full-size HDMI port, a mini HDMI port, a USB-C port, and a DisplayPort. Its default stand is more than a little reminiscent of Apple's Studio Display, but it also supports VESA mounting. Onyx International's lineup of Boox devices usually focuses on Android-powered E Ink tablets, which the company has been building for over a decade. These are notable mostly because they combine the benefits of E Ink—text that's easy on the eyes and long battery life—and access to multiple bookstores and other content sources via Google Play, rather than tying you to one manufacturer's ecosystem as Amazon's Kindles or other dedicated e-readers do. E Ink monitors aren't totally novel concepts, but aside from Onyx's black-and-white Mira Pro, it's not a crowded field. A company called Dasung offers a 25.3-inch 33 Hz color E-Ink screen for around $2,000, and a company called Acogedor makes a couple of smaller black-and-white models; there are also general-purpose E Ink displays made for connecting to a Raspberry Pi. But Onyx Boox is probably the most recognizable name in the game, and the Mira Pro is a much more attractive design than the Dasung version. For US buyers, note that the fine print on Onyx Boox's website says that "some countries may levy tariffs on the imported goods. For the amount of tariffs, please consult the local customs department." These monitors are shipping exclusively from the company's Hong Kong warehouse at the moment, and the Trump administration is currently hitting Hong Kong with the same tariffs as mainland China, and it doesn't seem like Onyx Boox is including them in the listed price of the device. Monitors may be included under broad exemptions that cover a lot of smartphones and PC hardware, but the situation is fluid and changes frequently.
