Review on JOHNWILL Portable Monitor Raspberry Computer 14", 3840X2160, Built In Speakers, 14-4K by Chad Martin

A 4K monitor in the daily PC test is quite cheap. A few features need improvement but at this price point it's fine for me. USB power can only work with HDMI or DSP ports, you need to connect two cables, which is not suitable for travel, the monitor can only work fully when you use the AC adapter, it can't work USB power with USB-C at the same time -Displayports use time. Also, the TypeC USB connector causes unknown device problems with a modern laptop. The side control button for the menu is really hard to use, you have to keep turning around to make sure you're pressing the right button.
