A:AnswerYes, but if you have two monitors you will need a display port which you will have to plug into your graphics card in the back of the PC. No where else otherwise only one monitor will work.
A:AnswerThe bars around the edges are very thin, but the bottom bar is pretty thick, but I’m pretty sure most monitors are like that because I compared it to my LG one and it’s almost identical. In my opinion 24 inch monitor is too small for me but that might be because I’ve only used 27 inch monitors before getting this one.
A:AnswerYou need a display port to display port or an hdmi 1.4 or higher to hdmi 1.4 or higher, an adapter would need to be an active adapter which are well over 30-40$ if you were to purchase on of them.
A:AnswerYes it works for Xbox but you will only get 60Hz because consoles are capped at 60hz/60fps
No you don't need a PC to power it on just plug it into a wall outlet and connect the HDMI cables into the Monitor and the Console
