Review on ✨ VisionOwl Y1 15.6" Portable Monitor - FreeSync Frameless Protector, 1920X1080P, 60Hz, Flicker-Free, Anti-Glare Coating, Blue Light Filter, HDMI by John Walsh

It worked fine for a couple of weeks when connected via USB-C. Then one day the screen just went black. After some fiddling, I find that it turns itself off when my computers are asleep. The solution is to turn it off every night or unplug it from my laptop as soon as it shuts down. For the price it's a decent second monitor and I can travel with it which is very handy.
