A:AnswerThis is not a TV and does not have a tuner or streaming apps. It is simply a computer monitor. It requires a desktop or laptop with USB type A for picture and power to work.
A:AnswerNot sure if it will work with a smartphone or not. It is powered via usb that also runs the video from your pc via that same usb cable. It does not need a separate power cable. Mine did come with a sleeve to carry the monitor and cable. It has a flip out stand in the back of it which is also where the usb port is. It does not have speakers.
A:AnswerYes, this will work with a Surface Pro. I use this all the time for work with my Surface Pro. Just remember that it's not a touchscreen like your SP so you'll have to do your work from the tablet still.
