After working with a dual-screen portable monitor for a month, I’m a believer
Having two displays in a single device is a growing trend that appeals to people with limited desk space or who need extra pixels to work with when on the go. But often, dual-screen devices, like laptops, are loaded with trade-offs that detract from the convenience two screens should provide.
I've tried using dual-screen laptops as my primary display/computing device before. But if I were to buy a dual-screen gadget today, it would be a dual-screen portable monitor. After spending the last month using a dual-screen portable monitor as my main work display, I believe that laptops should leave the dual-display thing to portable monitors. At least for now.

The monitor I tested is from JSAUX, a Shenzhen-headquartered company that has been around for eight years and has made a name for itself selling Steam Deck accessories.
