E Ink displays have earned a devoted following among people who spend long hours reading or writing. The technology produces virtually no flicker, doesn’t use the same harsh backlight as a typical LCD or OLED, and is considerably easier on the eyes over extended sessions. The catch has always been speed; these screens refresh slowly, making them suitable for e-readers but impractical for real-time interaction.
Color E Ink made things more complicated. Adding a color layer came at the cost of even slower refresh rates, keeping these monitors firmly in the reading-only category for most users. Bigme’s B251 Pro takes direct aim at that limitation, pushing a 25.3-inch color E Ink screen to reach up to 60 frames per second, a meaningful first for this panel type.

The screen uses Kaleido 3 technology at a 3200×1800 resolution, and at 145 DPI, it’s modest by LCD standards but respectable for E Ink, where the color filter layer tends to soften detail. The panel supports 4,096 colors and 16 levels of grayscale, while an adjustable front light with warm and cool modes lets you set the tone for your workspace.
What 60 frames per second changes practically is the range of tasks the monitor can handle without resistance. Scrolling through a long document doesn’t leave a trail of ghost images. A video clip doesn’t dissolve into motion blur on every cut. It’s not yet the fluidity of an LCD, but it’s the first time a color E Ink monitor has felt fast enough for an ordinary workday.
The B251 Pro accepts input through HDMI and DisplayPort. The USB-C port is reserved for firmware updates only, not video signal, which is worth knowing before assuming you can use it with a laptop’s Thunderbolt port. A wireless mirroring option covers that gap for cable-free setups, and the monitor ships with a remote control for switching display modes from your desk.
Spend enough hours at a standard monitor and eye strain becomes a familiar background discomfort: dull headaches, dry eyes, and that particular kind of fatigue that sets in before the day is even over. The B251 Pro is built for people in that position, specifically those whose work keeps them at a screen for most of the day and who’ve started looking for a less punishing alternative.
Bigme lists the B251 Pro at $1,599, currently reduced to $1,279 at launch. That’s a significant sum for a monitor that tops out at 4,096 colors and 145 DPI, and it won’t appeal to anyone who needs accurate color for professional photo or video work. For people who simply need a large, easy-to-live-with display and have started counting the hours their eyes spend under artificial light, the math looks different.
The B251 Pro doesn’t ask you to trade speed for eye comfort, and that compromise has defined this category since its beginning. Writers, coders, and anyone whose work is mostly text and reference material will find the 60FPS upgrade more compelling than any spec sheet can convey. The original B251 already built a devoted following at lower speeds; this version gives that crowd considerably less to apologize for.
