Good screen! Touch functionality only works if the charger is plugged in my case, I have a Oneplus 7. It comes with many cables and a powerful charger.
The specifications page list the monitor as 16:9, 1920x1080 while it's really 3:2, 1920x1280. The description page is correct. The monitor is really very thin, USB-C connection (and PD passtrough) are really good. Note to potential Samsung DeX buyers - to get DeX, you need to have a power source connected, otherwise the phone/tablet can only do miror mode. Output is always 1920x1080, so the image is streched a bit.
