I have two displays. The horizontal one lets me read two pages at once. The vertical one lets me focus on the one page. The brand names are Dell, Lenovo. Philips has a two in one display. One of them is E-Ink. If I were shopping I'd look for something like that in E-Ink color. https://www.yankodesign.com/2022/10/24/philips-2-in-1-monitor-adds-an-adjustable-e-ink-display-for-your-reading-comfort/ The Philips 24B1D5600 has a 23.3-inch 2560×1440 LCD monitor that you can use for regular stuff, and attached to its right side is a 13.3-inch E INK Carta HD display. One last thing, monitor screens have buried in their control panel a setting for the display "profile" which you can set to "paper" and there is a tech jargon keyword for automatically dimming the display when much of it is white background color.
