If this monitor really uses the Kaleido 3 display as speculated in the article, the color would be very mute and it would only be suitable for reading Manga or magazines.<p>From what I can tell, the Kaleido display uses a filter on top of a black/white display to show different colors. That's why they can do 300ppi on black/white content, but only 150ppi on color content.<p>The Kindle Colorsoft uses the Kaleido screen, and it's the worst rated Kindle product on Amazon for a reason.<p>For high PPI color e-ink display, the only option today is the Gallery (<a href="https://www.eink.com/brand/detail/Gallery" rel="nofollow">https://www.eink.com/brand/detail/Gallery</a>), and the only product that I know of is the reMarkable Paper Pro (reMarkable call it Canvas color play) which costs ~$600.
