13.3inch USB-C portable monitor FULL HD LED Display, With port (Dual Type-C, USB, HDMI, built in Speaker) for Smartphone Window 7 8 10 OS PS3 PS4 Laptop Computer copy extend screen

I primarily wanted this to use with a Samsung Galaxy phone in Dex mode. Dex is not supported directly, so you do need a USB-C 'hub' which triggers Dex, and then outputs to HDMI which this monitor can accept. The monitor may also accept USB-C video signals on its secondary port but I have not tried that yet. Other similar screens (from Asus and AOC) won't work because they only have USB-C input (for power and video), won't trigger Dex and don't have an HDMI input. This screen can also be used for other devices, e.g. games consoles. It comes with a good selection of cables for most applications. HDMI port is mini-HDMI (but it comes with a HDMI to mini cable).Two downsides: It is heavy - much heavier than an equivalent ipad/tablet even though there's no battery - I guess it's the steel case which seems unnecessary and the cover, thought functional doesn't provide very good propping up - it works on a flat surface but it's easy to knock (and then the screen slides flat) or on a bumpy train/plane it might fall over.This is a genuine review written by someone (me) who bought the product with my own money, without solicition, discount or bribe....unusual for Amazon, I know :-)
