New color e-paper monitors – 13.3-inch DASUNG Paperlike 13K and 23.5-inch BOOX Mira Pro Color

DASUNG Paperlike 13K ports epaper color monitor

Back in 2023, DASUNG launched its first color E-Ink monitor, quickly followed by BIGME B251 computer and standalone E-Ink monitor. Both were based on the same 23.5-inch E-ink Kaleido 3 color display with 3200×1800 resolution, and were rather pricey at $1,529 (Indiegogo price) and $1,299 (Kickstarter price), respectively. Let’s revisit color e-paper monitors in 2025 with two new models that were just announced: the DASUNG Paperlike 13K 13.3-inch e-ink color monitor and BOOX Mira Pro (Color version) with the same 23.5-inch E-Ink Kaleido as competing monitors launched in 2023. Those monitors are particularly well-suited for people spending long hours in front of the screen, and don’t need to watch video and play games due to the lower refresh and ghosting effect. It’s supposed to be friendlier to eyes, and there’s no blue light.
