Review on NIUTO Portable Touchscreen Extender Computer Compatible 14", 60Hz, 便携, 140-4K, HDMI, IPS, 4K, HD by Jonathan Lawson

This is a pretty good monitor, bright and with good color reproduction. But I've been led to believe two things that are actually wrong. First of all, unlike the photos, you CANNOT use Samsung DeX without a power adapter. You cannot connect this monitor to your phone without the power cord connected, it just flickers and turns on and off. Second, the second USB-C port on the monitor does NOT pass a data signal, so you can't use USB-C OTG from your phone to connect another USB device. In fact, as far as I can tell, using this monitor with a USB-C hub is absolutely impossible. At least the monitor charges the phone, but if you were planning on using a USB keyboard and mouse (like me) you're probably out of luck. It probably cost them 5 cents to add a USB-A port and make it infinitely more useful, but they didn't.
