Yes it does. You first connect to the internet (hard wire or wireless) then register the TV with Amazon and you get access to your Prime account.
#2 How do you set the tv up to use as your computer monitor
I forgot if the tv comes with a free HDMI cable. If it doesn't just purchase one and plug it in the TV HDMI port and plug the other end into your computers HDMI port as well... It will work as a computer monitor which is what I use this TV for. It works like a charm. Just make sure that the TV is set to the computer mode.
