I’ve been experimenting with a dichotomy of second screens for quite a long time at this rate. I’ve used a second phone-as-monitor, a laptop on the desk next to me, and, naturally, a “typical” secondary vertical monitor, which is the only one that’s truly stuck. However, one that did stick was the XIAO 7.5-inch ePaper Panel over the couple of months, driven by a tiny XIAO ESP32-C3 running ESPHome, and it quietly became the most useful “monitor” on my desk.
