Spending hours in front of a glowing screen is unavoidable for most people, and the toll it takes on the eyes is a problem the monitor industry hasn’t truly solved. E Ink displays offer a gentler, paper-like alternative that’s far easier to stare at for long stretches, but most of them are painfully slow, limited in resolution, and not really up to the demands of daily computing.
The Modos Flow is Modos Tech’s answer to that problem. Built by a Boston-based hardware startup, it’s a 13.3-inch E Ink portable monitor designed not just for casual reading but for all-day, focused work. It targets the kind of person who needs a real secondary screen but wants to spend less time squinting and more time actually getting things done.

Most E Ink monitors struggle as daily drivers because of their refresh rate. Traditional panels tend to crawl, making anything beyond static document reading a frustrating experience. The Modos Flow uses a custom board with open-source firmware to push its display to 60 Hz, enough to scroll through pages, type without noticeable lag, and use the screen as a functional everyday monitor rather than a glorified e-reader.
Resolution is also where the Modos Flow separates itself. In black-and-white mode, it renders at 3,200 x 2,400 pixels with a pixel density of 300 PPI, making text crisp enough to satisfy anyone used to retina-grade displays. Color mode brings the resolution down to 1,600 x 1,200 pixels at 150 PPI, which is a fair trade given how rarely E Ink panels offer color at all.
Touch and stylus support round out what’s becoming a surprisingly versatile display. Modos brought the latency down to under 100ms, so annotating a document, sketching ideas, or jotting notes with a stylus actually responds the way you’d want it to. It won’t replace a dedicated drawing tablet, but for someone who routinely works between a laptop and a secondary screen, having that input option without swapping devices is genuinely useful.
Its physical design is straightforward and practical. A built-in cover doubles as a stand and folds flat for travel, while VESA mounting holes on the back make it easy to attach to a monitor arm or desk mount. Three side buttons let you adjust brightness, contrast, and display mode without touching your computer. Connectivity runs through USB-C with DisplayPort Alt-Mode support, which keeps the setup clean with a single cable.
One of the quieter advantages of E Ink over LCD or OLED is power consumption, and that matters here. When connected to a laptop via USB-C, the Modos Flow draws significantly less power than a conventional secondary monitor, meaning your battery isn’t taking nearly the hit it normally would. It works with Windows, macOS, and Linux out of the box, so there’s no particular setup hurdle to clear. Pricing hasn’t been confirmed yet, but Modos has indicated it should be comparable to other portable monitors.
