The Nintendo Switch became the best-selling console because you can take it anywhere. But here's the frustration: playing on that small built-in screen, especially when two people are huddled around it, can strain your eyes and diminish the experience. Portable monitors solve this problem by giving you a bigger display that weighs barely more than a notebook: The Forhelp 15.6-inch portable monitor is now on sale for $59, down from its typical price of $79, during Prime Big Deal Day.
Unlike typical display technologies like LCDs and OLEDs, E Ink doesn't emit any light or shine it into your eyes, mimicking the effect of reading on paper.
